I recently purchased a 1966 Chevelle Malibu with a SBC 327. It has the 461 cast camel hump heads. Here's what I was advised to buy: Comp Cams 292H (kit), Holly 750 carb, Hooker Competition Headers, Edelbrock Performer RPM intake, Flowmaster cans, and a couple of other knick-knacks. Here's the issue: I just got the whole thing back together and (I believe) wiped three lobes off the cam!!! I REALLY need some help/advice before laying out any more cash... Anybody have any expertise on this issue???
