Going Full Roller!!

From the very beginning I knew I wanted a roller cam motor. When I purchased the 454 it already came with a nice 292 flat tappet cam. There was no need to change it so I decided to keep it. Once I realized I had to flycut the pistons, I decided to go whole-hog and go full roller. I pulled the Comp 292H cam and replaced it with a very stout Comp 304HR roller cam. The diferrence in duration at .o5o was nominal but the lift in the roller was .612 versus .550 in the 292H. Going roller meant getting roller lifters and a roller timing chain with thrust washer. All Comp Cam products. This added quite a bit more to the cost but got me what I always wanted :)
