A friend and I have a 455 that was previously built by a "professional". After some issues we were doing well with it in the 11.60's. Eventually it popped a rocker, damaged the stud and push rod, then the lifter. We were going to do just the top end with the butler 248/254/112 hyd roller cam, 330 cfm wideports, northwind, and the o ring intake extender. Well that got thrown out the window when we took off the e heads. In two bores there are two deep scratches so the engine needs to be bored out for sure. So now were thinking a rather large solid roller and install solid roller springs on the new hi ports.

We have the high ports, 1 7/8 dougs headers, intake, block, crank, and so on. To keep it budget friendy we are keeping the crank. I and hom have never done a solid roller. Looking for some suggestions there as far as sizing. Car is a 70 lemans with a turbo 400 prepped very nicely. Race weight is #3600 with him in it. We will be using a 950 4150 carb. The goal is deep 10's, like 10.50's. A cage is going in shortly. Any advice on cam?
