Header recommendation anyone?
Hi all;
I know this has probably been beat to death but I have been combing the internet and forums for headers that will work for my 1977 Vette, Calilfornia car with A.I.R. tubes. I want to keep it legal. Is there anything out there that is available? I am assuming shorties are the only way to go.
I am also considering:
- a crate engine (again the legality thing) vs rebuilding and upgrading the current lump
- 5-speed conversion (from the current TH350)
- steering upgrade
I have already rebuilt both f/r suspensions (the car rides like a dream), brakes and power steering components.
Thanks,
Jim

I think you can have the A.I.R. tubes installed on just about any set of headers by a good welder. Just buy painted headers, have the tubes installed, and then have them ceramic coated.

You'll need to see if there are CARB-legal headers for your engine - a little time on Summit Racing or another site will tell you what's out there.
I agree that the E-Rod is a great conversion...but it ain't cheap
...but if they don't have a CARB sticker, they're not legal.

Nice save, Billla, I didn't even think of that.
Here in Massachusetts, we have a safety inspection once a year, and vehicles don't get tested for emissions once they reach a certain age, so that sort of thing is not an issue here. I guess they figure there aren't enough of these old cars on the road to make much of a difference, so why not just leave them alone?

OP, keep ground clearance in mind when choosing headers, my collectors were ground flat when i got the car.

I believe Hedman makes hedders that will work with the air tubes. Check out their website and I think you will find something that will work for you.
I have the Hedman 68300 in my 77 with a crate engine.
I had the hedders ceramic coated they fit good and did not cost huge dollars.

Thanks for the input. I have pretty much decided that I want to push the legal limits with this car. I realize that a '77 CA car is probably one of the worst cars to do that with but that is what I have and it is what it is. Actually I have gone back and forth on what to do with the car, I have tried to sell it but no takers so I think I will have some fun with it. I can do a lot of the work myself and will try to keep the total spent around $15K so the E-ROD engine is probably not an option.
I went to the California arb site: http://www.arb.ca.gov/msprog/aftermk...rmktdevice.php
and if you search for Corvette some headers do come up so I can check those out. Scotty, great idea, there is a way you can hook up with a "smog referee" maybe they have some flexibility and could approve something like that although right now I have no idea.
I'll keep you posted on what I find out, I have some time to plan this project and probably won't get started until this summer some time.
Mick, how the heck did you get that picture of your dog?

I am glad I asked you guys, I thought the heat riser would eliminate the long tube headers but if they can accommodate it then that is great. I am thinking then that a set of 68301s, upstream of dual exhausts with two cats would give a significant performance bump while keeping the Calif ARB happy. Does that make sense?

To some degree. If you have some spare time, you should swing by my place and I can give you a tour of my car to give you an idea of what I've done to comply. You can also check out the headers.
