Re: fenderwell headers
Fenderwell headers will generally fit '55-57 Chevys and '62-67 Novas because there is a lot of room between the front tire and the inner fender panel. There just isn't much front wheel well room in a Chevelle, therefore fenderwell headers would necessitate the front end being raised, (such as the installation of a straight front axle, as noted in a previous post) and the use of small diameter front tires.
64 Chevelle Malibu Sport Coupe (original owner) car now has 427" BB, Jerico 5-spd. trans., Dana 60 rear end.
