I am running a Comp CRS 268H-10 Part # 20-212-2 in a 1970 318, factory heads,stock pistons now.
Performer 318/360 with a 600 Edelbrock and headers.Stock 904 converter 4.10 gears.
In a 63 Belvedere street car.
To me it's a pretty mild cam and is working well in this combo.
Video is pretty crappy ,not good with this stuff.
