I bought this motor a while back for an old project I had... Long story short, that project went down the road and the motor sat. Now, a new project is in the works and looking to make some minor changes. Below is what I started with... However, I'm looking at lowering the compression and maybe going to a roller cam. Running 93 pump gas, what would be the highest compression I could safely run and what would be the most radical cam I could use without jeopardizing performance? I also no longer have the 850 Proform carb so will be taking suggestions for a new one. 377 stroker - 13.5-1 compression, SCAT steel crank, 5.7 rods, forged Speed Pro Pistons, World Sportsman 200cc iron heads with 64cc chamber and 2.02/1.60 stainless valves, chrome moly pushrods, aluminum full roller rockers, Comp solid lifter cam (250/60 duration @ .50 532/558 lift, Pete Jackson, Victor Jr intake w/850 Proform carb on top of a Wilson spacer with full length headers Also, how do you think the new set-up would respond to a 150 shot? Any ideas on HP/TQ with lower compression and new cam?
