I have a 70 Chevelle with a factory 70, 350, LT-1 engine. I would like to install a functional Cowl Induction hood on the car. Does anyone know which spacer I need to use on the Factory Cowl Induction air cleaner to seal properly under the hood? Would it be for a 350, 302 or big block? Also, are the reproduction Cowl Induction air cleaners they sell today the same part for the 69 Camaros and the 70 Chevelles? Were they the same part back in the day? Any information would be appreciated.
Thanks
Thanks
