No cam?

 

No cam, bottom end is stock. I hear the Vortec heads add approx. 60hp-may be inflated, by bolt on.

 

Do a cam even if its a 90's lt1 take out

 

He was encouraged in his other thread to do a cam. He will be sadly disappointed if he doesn't.

 

Don't use the crap stock cam

 

How do I do it without removing the motor? Which one is a good one that's streetable and won't kill my gas mileage, plus not too expensive-kinda at the end of a budget I didn't have..know what I mean. Just a little bump stick nothing crazy, this is all going in my daughter's first car....What a way to break her in...LOL

 

You just pull the radiator, and a couple bolts out of the front clip brace and it'll slip right now.

 

A stock used LT1 cam will work well. You can usually find them for around $50. Drop the front of the oil pan, pull the timing cover, radiator and have someone hold the AC condenser up while you pull the cam out.

 

If I'm not able to, does anyone know based on the stuff I've got already.

 

I think the best "guesstimate" I could muster would be to think of it in these terms.

L03 TBI 305, 170 H.P.

L30 Vortec 305, 230 H.P.

So that is a 60 horsepower difference, as you indicated. But I don't know that we can attribute all of that to the heads. But my guess would be they get the lions share of the credit (Vs the Vortec EFI setup, and Vortec cam). But where exactly does that land you? 210? I guess only a trip to the dyno will tell you for sure.

I'd have to agree with the LT1 cam suggestions, or at least some kind of camshaft change over the peanut cam.

 

That's not bad, I mean 30% of the original is good. I'll see about the cam.

 

But the lt1 cams are for a 350 not a 305...Will that work?

 

hey mikeyt where was the quote or work on the heads done at? I was going to use the head shop in Virginia beach, been hearing good things.

 

I agree with DynoDave. I imagine without a cam change you would only make around 200-210 HP. With an LT1 cam I expect 230-245.

 

No cam with your parts I would say about 200-210...with a conservative LT1 cam I would say 230 -240. You might as well throw some Fel Pro 1094 .015 head gaskets in there to give a slight compression bump since your doing the heads anyway.

slightly high jacking the thread and I apologize but can you put a stock ls1 cam in a carb'd 305?

 

The stock L03 cam was the worst performance wise cam probably ever put in a sbc. To make any power out of your setup it has to go.

 

No. LSx grinds will not work.

 

Thanks

 

I got the heads from Barnetts machine shop in south Norfolk, talk to Stephanie, their number is 757-494-0530 they've got them in stock. I paid $525 for the heads done, shaved 0.030" to bring it down to a 58cc firing chamber, 3 angle valve job, new valve stem seals, pressure checked and magna-fluxed with new rocker arms and hardware, they have 184 intakes and 160 exhausts.

 

I've already got the headgaskets, I didn't think about getting ones that were thinner. I'm using the GM 0.028" ones

 

This is a cam I found on ebay will it specs work for my build up:

1992-’95 350 WITH ALUMINUM HEADS - The 1992 Corvette had a steel roller cam with a shallow hole in the snout that measured .450" in the front and tapered down to .240" at the bottom. It had a short dowel (.320") that was used to locate the timing gear and a hole with 16 splines in the center of the gear for the stub shaft that drove the early distributor. The 1993-‘94 H.O. cam had a few subtle changes, but all of the early H.O. cams are the same for all intents and purposes. They can be identified by the number "241" stamped on the barrel in front of the first lobe.
