Thermoquad air cleaner

If you are going with a stock carburetor then I would go with a correct air cleaner.

I'd go with a stock 1975 4 bbl. Air cleaner. They were not that rare on C bodies. Get on FCBO and find a gent "C body Bob" and you can get a stock lid for a 360 4 bbl. For pretty cheap.

Then if you want more air flow then turn the lid upside down. (Old skool trick) but keeps the timeless stock look
