I have a couple of 409 projects going currently as well as this 427/390 BB that will be in a 1966 Vette Coupe. Original matching engine/car.
Due to the buzz of flat tappet valve train failures, we went with a hydraulic roller cam that is similar to the GM 390 HP camshaft id 1966. Took the block over.030.
Reconditioned rods with bronze bushings with forged 10,5 compression pistons. The entires rotating assembly was balanced to an incredible 1.2 grams. Numbers were preserved on block deck. Carb is mock-up.First BB I've done since my L-78 69 Camaro.
