Re: Isky Mega 280 cam
I would use that L79 cam. It probably will perform better then the 280 in THAT engine. The GM engineer's put the largest cams they could into those engines running those heads. If you want solid then use the 30-30 or the off-road cam, and boost up your compression ! It is true that cam technology has improved in the last 40 years, but so has head technology. It is not good to stick a new modern designed cam into an engine with the old double hump heads. It is like installing Windows 7 on an old P3 computer. It might work, but not very well. The intake ports are just too small on those old heads. If you spend a lot of money or time on those heads, they MIGHT get the job done. The port velocity created by these new cam's is way too much for those small ports !
