My machine shop owner friend is trying to get a 510 inch BBC ready to dyno tonight. It's a little different combo, 4.375 stroke, 4.310 bore tall deck, 6.700 rod. It has ported Pro Topline 320 cc heads, 13.5:1, Victor intake. We have three carbs to try, 1050, 1150, 1050 Alcohol.The cam is .740 lift solid roller, [email protected] Should be interesting with the longer stroke. It should make a ton of torque, especially on Alky.
