350rwhp
I know, SEARCh, I've used it and read countless threads already. I have a 1991 C4 automatic coupe. I'm about to close on selling my house and looking to do some modifications. I know the exhaust is restrictive, and thankfully we have NO emissions whatsoever here. So I know headers and full exhaust are in order. What is the better intake to use? I've had Lt1 and LT4 f bodies, but this is my first vette. I am not looking for a drag car ( I may go once or twice just to get some #'s) I really want something that can get me around 325-350rwhp and be able to use it on the road. So What are some good, yet affordable heads, and what is a proven cam. I hat a hotcam in my last transam and was happy with that, I know its old and pretty mild.
Again, just looking for a proven h/c/i setup that can get me around my target power. I dont have tons to spend, but $2500 is probably reasonable off the bat.
Thanks
Devon

this is a stupid question. Is the hotcam for this the same as the one is the LT1-4 car? If so, I have access to one cheap. I dont think I wont to deal with the SR. Also I noticed several different versions of the miniram. Do i need to upgrade the rr's?

Yes on the Full roller rockers and springs. Another approach woulld be to port your stock intake and heads, ZZ9 cam, 1.52 full RR's and a custom tune. Your 1991 has high compression heads that are I believe 10.25:1 already.

Thanks. I really would rather swap a new head and intake on. Mine are higher miles anyways. I'm also open to used setups, so I guess I'll start searching the for sale section and ebay.

I don't see how you are going to do all that for $2500. You are looking at closer to $4000.

Heads appear to be like 1200 ish online at most places, intakes are like 1000, I can get a cam for under 300. I have buddies who are pretty mechanically inclined, so labor will be a minimum on this. Where is the extra $1500? I wasn't including headers and exhaust in my $2500, that will be seperate expenditure.

You didn't say the exhaust was separate, but in any event you left out; roller rockers, installation supplies, gaskets, shipping, any new sending units or wiring looms etc. You won't be able to do this for $2500. I'm not arguing, just stating my opinion. Go for it, but keep up with ALL you spend and you will be suprised.

I appreciate it. I'm looking forward to it. I'm really surprised who much TQ these L98's put out! Once I get started here in the next few weeks, I'll photograph everything and get some dyno numbers when its done.

Not a problem, I'll probably just devote a whole album online to it. Also starting to look at the Lt intake as a cheaper alternative. Was reading info on vaders website and there was a 3rd gen fbody that had a super ram and then switched to an Lt1 intake. he had an expected loss in Tq, but the car ran almost identical 1/4 mile times. The SR being better, but the Lt1 intake costing about half. I can get an Lt1 intake CHEAP or maybe an LT4 one. Will the LT4 work ok? Can a LT stlyle head be used then? If so, I'll order the LE1 kit from Llyod @ eportwork.com
Thanks guys!
