Crossbolting a 428
FFR428,
A lot depends on what sustained rpm you are going to run!! Is this car meant for the track, or is it mainly a street car? If it's primarily a street car that will only see occasional and quick bursts up to 6500 rpm, precise blueprinting on the mains and rods along with main studs will suffice. You get a far superior clamping force on the main caps with the fine thread of the stud. This cuts down on cap walk quite a bit if held under 6500 rpm.
By the way, I can get 519hp out of a 428 with 9.9 to 1 compression, Edelbrock heads, 850 carb, and a hyd roller cam with only 236 at .050 duration. Tecnology has come along way since the 70's.
