I am building a 1955 Chevy Truck Prostreet look. The truck has a Ford 9" 4.11 gears with 31X18.5X15 tires and a 400 Trans. With maybe a 2800-3000 stall? I will use the truck manly for driving to the meets and shows with very little track time. I want a nasty idle and good power. I am gathering all my parts for my motor build. Here is what I was thinking and would appreciate any input on what to add or change. I am using a 454 40 over block, stock stroke, stock rod size. I will shoot for 10.0 to 10.5 compression, I have a set of Merlin 320 CC iron rect port heads, A Weiland Team G dual plane intake and was planning on using a Mighty Demon 825 carb DS or VAC? I want to use a Roller Hyd camshaft. I was looking into the Big Mutha Thumper but maybe something is better? Thanks, Ronnie
