I go with mostly all used parts. Most people on these forums sell things because they are going a different direction. I try to figure out my direction and stay with it, then gather parts for it from the for sale sections and from ebay. Here is what I now have gotten used, and the prices include shipping:

3.07 rear for $300
2800 stall tcs converter with anti-balloon plate for $360
CC503 cam, never installed, for $200
TFS chromemoly pushrods for $55
113 heads reworked by Precisioin Motorsports for $550
Timing chain, new takeoff of crate motor for $23
Crane Hi-6 ignition box for $110
Hawk HPS brake pads for $55
Stealth Ram with vette plenum, with distributor for $755
24lb SVO injectors free from a friend with a Cobra

I have bought many new parts like shift kit, zex kit, hooker headers, summit roller rockers, full stereo system, and many others. But for the performance parts I try to shop used, because when you buy new and install it, at the end of the day, it is used.

I found my 92 vert sitting under a tree covered in bird shyt, owner in jail. Paid $5500.00 for it and thought I would be good to go for a while. I test drove it and the owners brother drove it 60 miles to me. While driving around I went past 74 MPH and the whole car started to shake. Turns out the tranny was shot. $1800.00. I've got about 5 or 6K in it and it still needs paint and wheels. Haven't done a performance mods and prolly won't.......well....maybe...a few.

Several crucial parts were delayed and nordic winter interrupted my project. If I'll find a new warehouse for my company I might be able to continue during the winter, if not I will do it next spring. Meanwhile more parts are on their way

Well I'm not going to go too far with this thing. Wheels and paint, maybe a catback, needs a brake booster. Then thats it... I hope.

For many the process of getting there is more important than the destination (did that make any sense in english?).

For me: first 3 years I only modded suspension and drove 60K miles. After that (4 years) I've build it more and only have driven total of about 6K miles. Sometime in future most of my mods are done and the Vette becomes the car I dream about and then I will drive it more and only mod if necessary.

this is the C4 paradox (for C3, double it)

the power is completely inadequate in stock form. i loved the body, the interior, the tradition......but the power sucks. sorry to those who are all impressed, but i'm telling you it sucks, period. and don;t give me this crap about stoplight to stoplight parties. who the heck give a damn about that? that means nothing and admits inadequacy from the word go. meanwhile, the kids in the 4-bangers are laughing.

so......you must endeavor to fix it. for an L98, that means a complete revamping or just do nothing at all -- so that's heads, cam, intake, exhaust -- and another $1-2k in for the "while you're at it's". final ticket -- typically $4-7k to fix the problem GM gave you. thanks GM, you bastards. accept it or deny it, that's the gig. or you can just another crate engine, 383 or 396, with the intake of your choice. still the same price.

then live and enjoy it the way it should have been in the first place.

Considering many C4s are twenty years old and we can spend our money modding instead of fixing our cars, we should be thankful GM built them this reliable, instead of raggin' on GM for the lack of power. Hey, that's what hot rodding has always been about. As some have said you can find good prices on stuff here on the forum and other places. Some of my purchases; Superram-$900, new 1.6 rollers-$190, new roller chain-$50, 30lb injectors-$100, complete engine out of a 90-$500 of Craigs List. All this stuff and more is sitting in a corner of my shop waiting to go in my 86. Now if I can stop working on customer's car and work on my own

Have Fun, Paul

You crack me up. You're idea of a mod is basically lift the radiator cap and pull a new motor under it.

I agree though, how difficult would it have been for GM to make the heads flow better, the intake flow better and put a little larger cam in the car. During manufacture these things could have been cheap and easy.

The L98 could easily have been a 350HP car off the showroom floor.

The L98 still wasn't bad at the end of it's run in '91 (250hp & 345lb. ft. of torque).

Ya gotta remember that the L98 was not a slouch in its time.

Time has changed and so have people's expectations. The same L98 is nothing in today's standards

No doubt. All I'm saying that Chevy could have done some very simple things, things that we do and talk about here every day.

If they just let the heads, intake, and exhaust flow a little bit. No real engine mods, just loosen up the airflow through the engines.

What could it possibly cost to make the standard 113 heads flow 180 CFM or 240 CFM, not too much I'd say.

Or to put a little more cam in it. What's the price difference between grinding one cam over another for GM?

I think they could have done a few things better, with the same parts.

in the world of medicrity and bloatedness, bean counters rule.

case in point, the intake. made for a 305, not a 350. they hurried up the get the '85 released, the intake was an afterthought, yet they ran it thru SIX FREAKIN' YEARS of production. too cheap, lazy and/or stupid to do it right.

Serious , what could it possibly cost to make parts that flow, and a cam? Not much more, if anything at all.
