Turbo engines need to be built to turbo engine requirements. Building one then running it NA for awhile will not make you happy.

What is you power goal? What is your budget? These 2 areas is where you need to make decisions first then you can go forward.

Ok well I dont need the turbo it was just an idea because I was afraid I couldn't get to my goal of 400hp-500hp with the limited selection of carb compliant and emissions friendly parts. With that said I'm not necessarily working with a budget but I Dont want to spend more then 5k on say a new block and crazy performance parts I just want to reach my goal within a reasonable price...so I'll be reusing my current block and carburetor to save money and stay compliant. Shark gave some good advice and any you can offer is greatly appreciated.

A set of 180AFRs, and mild hyd Roller, air gap intake to fit the Qjet you can make a nice 450HP and pass emissions.

When will you be due for another smog check? I'd like to see how the motor does.

This thread makes me feel better since I'm looking for a c3 and thought I had to stick to a 75 or older, but looks like that's not the case.

Will this kind of power still be attainable going through the 2-1-2 exhaust system? To be smog legal in CA this configuration cannot be changed.

The air gap won't have EGR - though I've wondered if you could fit a custom throttle plate to handle that.

April. If you're nearby and would like to go for a ride in the 78, you're more than welcome.

If you're doing a complete rebuild - and with the original block, then by all means build a smog legal 383 ! ( roller cam and AFR heads )
Build for max torque and match-up the rear gears and torque converter to the powerband.
You'll have "tire-frying / Corvette power", just like the proper engine should be.

I have a set of AFR Comp. package 210cc for sale if you are interested. Purchased in 2005 and put no more than 10,000 miles on them. They have 76cc chambers. I paid 2000 for them.
