I would like to do a cam swap in my 305. What the biggest i could go without messing with a stall, or porting my heads. I will replace the springs, Just looking for some ideas now.

how about an LT1 cam??

Cant seem to find one at the moment. one guys has one over on fbody but it takes him days to respond to any of my msg's. And on ebay there always in a whole package with the rest of the valvetrain.

That what I have been looking for in the first place.

So i guess if anyone has a stock lt1 cam that they are willing to part.

theres always someone selling a cheap lt1 cam if not this site check ls1tech all those lt owners change cams and sell them cheap. all you gotta do is ask.

I think I got one stored. I'll have to look.
I'll get back to you. I think it is a 705.

Check on camaroz28.com, that's where I found mine. That sight caters to all generations of F-bodys, so you'll find one in a hurry. I just put out a wanted ad and had one within a week (out of a 97, with 30,000 on it).

one just popped up in this sites classifides yesterday.

I have a brand new, never run L31 cam (same as LT1 B-cam except for the shorter dowel at the nose, which is what you'd want anyway). $50+shipping. Or if you're not in a hurry, I could drop it at the shop in Dayton where I go and you can pick it up there.
The LT1-B is ground on a 111 LSA which gives it a better midrange power curve than the LT1 F or Y cams. Would be especially beneficial in a 305 motor.

yeah I paid $230.00 for my cam.

So its all in what you want to spend.

Hey guys,
new to the forum here, and Im also looking for info on LT1 cams. I got a 94 9C1 caprice engine (350 5.7L) that im going to drop in to my 86 trans-am. Would it be ideal to put an Lt1 cam in there?
Thanks

if that is an LO5 motor then yes itll be an upgrade.

Yup, it's an LO5 motor. So besides an LT1 cam, what other parts would work good on it?
Should I start a new thread?

If it's the original engine in the 94 9C1 and it's a 5.7, then it's an LT1, not an LO5.
Be careful, 94-96 9C1's with the "baby LT1" 4.3 L also exist.

The iron head LT1 engine will perform about as good as the same 94-96 f body engines if you put the real LT1 cam or the stock LT4 cam in. The big body engines used a much smaller cam, which is the same as the 96-99 L31 cam.
A lot of LT1 people say that the cast iron heads flowed better than the aluminum heads the same years.
GM liked them so much they used the same basic head on the L31 except for the reverse flow cooling system.

Heh heh......"The iron head LT1 engine will perform about as good as the same 94-96 f body engines if you".........just leave the cam alone
Because of its superior LSA of 111 deg and installed ICL of 107 deg, it actually outperforms the f/y LT1 cams up through the midrange, whereas the f/y cam's emissions-slanted goofy LSA and ICL sacrifices midrange power just to eek out a few numbers at a 5200-5300 peak versus the b cam's 5000 peak. And there's more to the story: With the same intake and exhaust setups, there's even less of a peak hp difference than the 15-25 hp Chevy advertised.

Why exactly are LT1 cams a good swap over for the 305? I've been thinking about getting a cam for a while now, and now someone in my class is building up his LT1 and he's probably going to be changing the cam, so it sounds like it might be a good idea to try and get his old cam off of him.

Would an LT1 cam require any mods to the heads? I would be putting new springs in anyways, but other than that? Is there any specific LT1 cam that would be most or least beneficial?

ok i got the casting #'s
on the block: 14093638
on the heads: 14102193

Does anyone know the specs on this engine?

I'm not sure those are legitimate casting nos.
Look here for ways to identify LT1 vs L99:

thats an LO5. those 193 are 350 swirl port heads i know i have a set sitting at work. those i think dont quote me rated maybe 190-215? im probably wrong just a guess.

Can anyone tell me what cam this guy has. Would go good with my iroc

eh whatever it is its too big for that motor.

I have a 1991 rs with a stock 305 tbi what would be the biggest cam I could use also any other tips for increased power on a somewhat low budget would be greatly appreciated thanks

I am also thinking about buying a cam for my 91 305 TPI. I read these work okay with stock computer.

Comp Cams Xtreme Energy 252 Camshaft (#08-407-8)
- Advertised Duration 252/258
- Lift .472/.480

Or:

Comp Cams Computer controlled (#08-300-8)
- Advertised Duration 262/264
- Lift .450/.480

Would that give a thump to the useless because thats what I'm looking for

Would that give a thump to the idel because that's what I'm looking for

I will be using this cam in my 305 after it's rebuild ( it's getting dyno tuned after the rebuild also to tune for new injectors and higher compression) http://www.summitracing.com/parts/CCA-08-305-8/
