What do you guys think of a 400 small block: 2 bolt mains, 8.5:1, new flexplate, performer Edelbrock intake, 266 Crane camshaft, Clevite, Felpro, full rebuild? He's asking $2500, and will give a GM warranty and includes install. The builder figures 280 HP at 4600 RPM and 400 ftlb. He also figures cruising at 2000 rpm. Does that sound right? I would be switching over 4.10 gears and 37" tires, T350, and want to anticipate a decent powerband. I know I'd require a fuel pump, and rad, possibly carb, belts, water pump, what else should I expect to buy. If I don't watch my budget I might have a new motor and not be able to afford to drive the rest of the summer. Any thoughts for me?
