Comp Height
Recently got some Diamond Pistons for an eventual motor build, the compression height is 1.250. When I spoke to Comp star, they recommended building a 355 with a 6" rod, and that 383 with a 5.850 rod would require the block to be decked .050 which they didn't recomend doing. Like to See what you guys thought, it may very well get a 355 with a custom cam and be done with it.
