302ci Stock Short-Block
For our test, Chuck Lawrence loaded a stock short-block 302ci engine onto the SuperFlow SF-901 engine dyno. The rotating assembly was completely stock, and this short-block has served as a test mule for close to 15 years. Amazingly, this engine has seen large amounts of nitrous oxide, boost, and lots of rpm, as evident in the runs we made. The 302 has 9.01:1 compression, and is equipped with a mild hydraulic-roller camshaft, P-38 cylinder heads, and Crane lifters and rocker arms. The induction system was a 750-cfm Demon carb atop an Edelbrock Super Victor intake manifold, which is overkill for the application.
To show the other side of the spectrum, Kaase built a 427ci Dart-block-based engine. The big-inch small-block was topped with a set of the P-38 cylinder heads, Crane rockers arms and lifters, a Comp hydraulic roller camshaft, Edelbrock Super Victor intake manifold, and a 950-cfm carb.
