Used Weiand single plane aluminum intake for a small block Chevy. Good shape, no stripped holes or cracks. Best for high rpm drag or circle track, but I used it on the street on a 425hp 355 without issue. Decent mid range torque and excellent top end hp. Yes it is old school, but tried and true. Will work with a square bore carb, spread bore (with an adaptor) or easy EFI system.
