Default C3 Restomod Pro-Touring

Hello, I am almost 15 years old, and my father told me that if I want a better car I have to build it, so I decided to do a C3 corvette. I would like to know what the best year to do is and whether or not there is a company that makes DOHC piston heads for a small block chevy, and how much it would cost to acquire them. I am also a resident of San Diego, California, and I know that there are strict emissions laws here. I'm looking for a good engine and transmission/ transaxle, suspension, and head and tail lights. Interior isn't too big of a deal for me either. Also, what are some good sized wheels, because I really like the new wheels available for the c7, but they're huge 19" and 20". And, with the wheels, some good disc brakes, preferably with ABS.

Seeing as there is no provision for a timming chain to go from the crank to the heads I'd say even if you made custom heads which would be expensive, making provision would be difficult, if you want a "chevy" v8 with dohc buy an LT5 it's the c4 zr1 motor it's the only vette motor with dohc

Unless you have a strong aesthetic preference for a certain year you should get one where you get the best condition for the money. That will probably be 1975-1982.

No DOHC heads, and you don't want them. Don't believe the hype. You can make just as much power without the complexity and space requirements of DOHC.

Transplanting a modern era LS-style engine gives you good bang-for-the-buck power. Anywhere from 350hp to whatever your wallet allows. There are LS engines making 1000+ hp.

Hi iP,
Welcome!
It sounds like you have a pretty ambitious car in mind for someone your age!
In order to help you move in the right direction it would be good if people here had some idea of the $$$ budget you have to buy a car, and then the $$$ budget to make it into a Pro Touring car.
Also, it would help to know what sort of experience you may have working on cars, the sort of garage you'll have to do the work in, the tools and equipment that will be available to you, and what work you might be doing yourself and what you might be sending out to various shops to have done.
With an involved project it's important to have a good start or things can get out of hand pretty quickly and expensively!
So, what are you thinking your Pro Touring car will be…. both in your dreams and in reality?
Regards,
Alan

You realize that the fabulous pro touring cars you see in magazines and on line have usually had a zillion $ spent on them, right?

Totally up to you. Your choice. What model year do you want?

Free unsolicited advice: why don't you and dad get together, talk about this, and make some decisions between the two of you? Might help you decide where you're going with this project.

Good luck.

The OP doesn't list the state of residence but you may want to check your states emission laws when deciding on a year. Here in Kalifornia, all 1976 and newer need to be smogged so that limits your options for mods.

But what about V-TEC? just kidding, I just prefer larger exhaust valves for better flow.

Welcome again, and glad to know that you are young. I was 15 when my dad gave me my '72. I am early 20s now and still own it. Glad to have another young CF member, especially a C3 CF member.


Like I said in the intro, you can stuff just about any motor you want in a C3. I have no doubt that you will get your numbers, the only question is on what platform.

This can all be done without the added weight and complexity of DOHC. A cam-in-block V8 is one of the best packaged engines out there in terms of power for the physical space taken up by the engine. Why do you think the RX7 guys are getting rid of their triangle nightmares for big cube LSx motors?

I vote LS3 if you want a car that will GO.

California enacted some quite stringent emissions standards for anything newer than a '76. If you have a '75 or older you are exempt and can run any engine/exhaust setup you want.

Edit: run any engine/exhaust, not ruin. Though you can ruin the engine if you want.
