I recently changed from a flat tappet cam to this roller cam.
Installation was straight forward.
The pushrod measuring tool was very helpful. I have Edelbrock D port heads with .060" head gaskets, 1.65:1 rockers and Morel lifters. This combination required 8.650" pushrods. that are not included in the kit.
I installed the cam into a 455 engine with 10.5 to 1 compression ratio. The engine idles smoothly and has good vacuum.
I haven't had the engine on the track yet but it moves my 69 GTO very well.
