Ok got a couple qustions.
I have a 305 tpi with 87,000 miles on it and i want it to run 13.5-13.9 no spray and 13.0 with a 100 shot. Its a auto.

a cam swap and headers W/full exhaust would be a good start. i would even consider a holly stealth ram intake. alittle pricey but you can still use it if you deside to go with a 350 later on.
another route would be tration aid's too. box the LCA's or get tubular ones. adjustible shocks will help out alot. and TIRES!!! i remember you posted something about getting Drag radials, did you deside which ones you wanted to go with yet? --

Ok here is what I got.
B/f drag radials
3.73 gears
1.6 rockers

I thought that would be a good start.
But im looking at a comp cams cam kit. One thats has got everything. Cam,springs,lifter,puchrods,retainers...
I dont know what else just shoot some info at me.
In seriously thinking about spraying a 50-100 shot i dunno . --

lower control arms... for the rear suspension... some people call them trailing arms too...
do not do anything on the 305 that will require a gasket change. dont start pulling your cam, then you'll have to pull the radiator, and it gets messy from there... if your going to change intake runners and plenum... go for it... headers are ok too... but dont pull your cam... dont change your timing chain... dont change heads... its more work than its really worth on your 305... i know you said you didnt want anyone to tell you to buy a 350, but your better off... all of the things i have seen you list that you say you have, will all transfer over to a 350 with ease.
build a 350. 10:1 compression, roller rockers, aluminum heads, sweet cam, fully balanced rotating assembly... mean while your running a 14.5 in your 305 with a faster motor in your garage... know what i mean?
someone has to agree with that... --

with the lower control arm's some people just take a flat peice of steel and weld them in to box them in and make them stronger. sortof a backyard thing.
what to LCA's cost in the aftermarket? like 150-200 bucks? yea..... im a cheapass.  --

"No one will give me some honest opinions."
"I always get jackass like you that have nothing to say but you still waste peoples time on the thread."
91gta, whatever your smoking, it must be good.
youve posted asking the same question at least 6 times in the past (and that doesnt include replys in other posts, or this one), and all you got were honest answers from people.
myself as well as other people did tell you what to do to make your 305 pull a 13 second run.
the best was when i asked you why your not swapping the ls1 drivetrain left wasted in your garage, and you said you didnt trust yourself. then i told you you didnt have any buisness behind the wheel of any car. and then you said you were a good driver. cut the shit pal.
just becasue you dont want to hear honest opinions from people who say that its cheaper and more effective to use a 350 sbc than it is to use a 305 sbc, doesnt make their point invalid or dishonest, in fact it makes them smarter for using their money more efficiently.]
why dont you look around and look at all the helpful stuff leadfoot has posted, and go back and look at all the helpful advice youve shared with us.
"Unless you have somthing that I want to here ....
Dont say anything."
the same could be said about you.

lol I mean i dont have a problem with him its just why waste your time typing it?
I dont know about the 11-12 sec car thing.
The fastest car i have every been in was a
2006 gto ls2 6-speed with a paxton supercharger in it. And that was when i was like omfg that is unreal.
But i do have a question.
The only nitrous kits i have seen for a tpi is the NOS brand and it is only for 100-150??
I really dont want to run a 100 shot right off the back. I would like to run like a 75 then a 100.
But i dont think i will use the 150 cause that i think is to much for a stock bottem end.
Any help is great.
( and dont say buy a 350) ...(lol)
Also i have a question for leadfoot racer. How much did the shop charge you to redo your block.
And what all did you have dont to it?? --

well i know you don't want to hear it but a new engine might be in order. you start messing with nitrous (which turns into an addiction) you'll end up doing some dammage to your bottom end over a short period of time. and at 87K you'll be lucky if those rings make it to 100k.
nitrous is like a drug, everyone ive ever known gets hooked and wants to go bigger and bigger. you start out at 75, then "eh well ill go to 100 to get alittle more power". then 125, then 150 then 200, then eventually BANG! you need a magent to pick up all your parts off the track.
i would think about peiceing together a 305 or 350 short block over the winter with forged internals. not a bad idea to have a backup. and sbc parts arn't to expensive. hence the reason everyone argues to go with the 350. but if your on the hose you'll get some good numbers with a stout 305. --

i'm currently building a 350 for my camaro and i'm into it for $850 so far, and thats:
headers
y pipe
rings
bearings
gasket set
head bolts
stainless engine bolt kit
pushrods
cam/lifters
timing chain cover
block/piston cleaning
noisey gear drive
i paid $200 for the guy to hone, ridge ream, install cam bearings and freeze plugs... he also cleaned and checked out my pistons for me too...
and for $300 he is going to deshroud and do bowl work to a set of 58cc chamber 305 heads i have.
honestly dude... nitrous will blow up yer little bottom end... i still dont have a good understanding why you havent just tossed in your Lx1 motor... that'd be the balls... i'd do that before anything --

well, then he should start at 150 and go from there. it would be fun to spray a motor to death knowing that you had a back up ready to rock.

i agree that a 350 will get you more bang for you buck ... put a 305 is like any other motor you if do the right mods you see power with out going broke.. heres a few things other than than motor work you can do such as tires.. gears and tighten you suspension such as subframe connectors a stiffer car will launch better.
as for the motor he is a link my friend used everythign but the heads in his 87 monte ss much heavier than a 3rd gen and he smokes 4.6 stangs... so if you get the right parts and get them running just right you hopes of a 13.5 is very possable.... let us know how thigns work out

I want to rebuild it and make it a stroker but I dont know what all is involved in all of that.
What crank?
What pistons?
What rods?

And I had my block redone. I see that this kit comes with a .30 over option? Should I just go ahead and have the block bored or would it even be worth it?

Also would do you think this kit would add if it was bored .30 over??

dude, you just dont get it. youre getting 14ci less with a more expensive stroker package than you will with a 350. for the price of the stroker package you can get an lt1 from a caprice.
not to mention that the base 383 kit they offer is $200 less than your [edit]334[/edit] kit. that $200 can get you a good 350 block. thats 49ci more than the 334ci for the same price.

i couldnt give two shits less if you waste your money getting comparable performance. i just want to make sure you know how stupid you look doing it.
your not looking if you cant find a 350 roller, theyre more common than you might think. i just found a couple on ebay.
ive also seen a couple 383s run those times without even trying.
and this is my info, dipshit. people have been trying to help you save money. i think you have a hard on over the 305. big deal, you have a stroked 305 that runs 13s. theres STOCK 350s that can do that, with less money involved.

dont motor swap... stick with the 305 but bolt up the new Stoker 335 Ci.. It costs only about $599 from enginekits.com This is known to add about 100 HP to the Stock application without any other mods, Except maybe Flow of Fuel. Of course this requires some basic engine knowledge and building the motor from the Bottom UP. But once your Car runs with its TPI intake you can adjust the FPR to compensate. Viola 1 Hp for every Cube.

The torque converter selection mostly depends on cam selection. For the cam you're looking at there, I'd say to get something with a 2500-2800 stall. And I'd recommend that you use a tranny cooler, but you might be able to get away w/o it. I'd at least put in a gauge to see the transmissions temp. especially if you don't put a cooler on it. Also be sure that the converter does have lock-up in it. Then for the cam, the one I'm guessing you're looking at has specs 290/307 adv. duration, 230/244 duration @.050" lift, .510/.540 lift, and 112 degrees lobe separation. The lift of any cam used on 1.6 rockers will be whatever lift they say divided by 1.5, then multiplied by 1.6. That would come out to .540 / 1.5 x 1.6 = .576" lift on the exhaust side of that cam. That is a decently high lift, but when using 1.6 rockers that's what will happen. The lift doesn't really determine if the cam is too large for a motor. The duration is more of what says the cams size. That duration of cam you're looking at will definitely sound nice and lopy expecially from the smaller size of a motor. Also that cam is probably the biggest that I'd think to go with what else you have going on, and you could possibly even step back one size to attempt to get just a bit better idle quality, gas mileage, and streetability. -- The crap gas wonder: 1982 Z28, forged 10:1 383, ported 23* trick flow heads, 246/254 .558/.558 hyd. roller, 3.73's, 3500 stall

I want want it to be as streetable as possible.
What cam do you suggest I cant really seem to find the right one for a 305 tpi.
If I was to run a smaller cam just to where you could tell the cam was aftermarket and it had just a little rough idle. What size stall would you suggest.
Also is a tranny cooler hard to install? ( i have never put one in)
Any info is great. thanks a ton. --

Cams are a hassle. for streatablity get one that like 230/244 duration up to about 250/260 etc. you will want the lift to follow in with the Head Spec. Don't go over or you will bend up your Pushrods.
For a Stock head you might want to stick with about 4.0 lift... if you change the heads go a little larger.
Just because the Cam Rates between 1200-5000 doesn't mean you dont have an Idle. Idle will just be Lopey and you will need to rev it up to 1200 to get to the Torque band.
So for Streetablity if you get one that is Probably from Idle-5500 or 1000-5500 etc... that would probably work out great. This way you can still drive the street and get the Added RPM and Torque needed for smoking that Mustang

As for changing the Torque converter the Idea is to get one that can handle more HP and Torque, only because the Stock one will only hold up to about 350 Max ft/lbs if your lucky. Stall should be increased to meet the Low level of your powerband.
Good Luck

You could actually go with the cam that specs: 266/276 adv. dur, 210/220 dur. @.050", .500/.510 lift, and 114 degrees LSA. Since you're planning on using 1.6 rockers on it, the valves would act like the cam is specd. at 213/223 .533/.544. This way the duration gets knocked down from the previous cam so that you get better vacuum for your brakes, better idle, better gas mileage, but yet still make good power from the still decently high lift. Also they say nothing about needing a higher than stock stall converter. I like to think of it like this: The heads flow more air the higher the valve is lifted (in general and mostly only really applying up to .600" ), so the more lift you have the more peak power you make. Then if you have higher durations, the power is also farther increased, but also increases the rpm at which peak power is made at. So the ideal "street car" cam would have a small duration for driveabilty, nice idle, good vacuum, and mpg while having a high lift to flow enough air to make high power. -- The crap gas wonder: 1982 Z28, forged 10:1 383, ported 23* trick flow heads, 246/254 .558/.558 hyd. roller, 3.73's, 3500 stall 11.44@117.8, 405rwhp, 337rwtq Video: http://s50.photobucket.com/albums/f305/fast82z/?action=view¤t=fast82z20062.flv AIM:fast82z (Feel free to hit me up.)
