  1. What size BBC short block best fitted with Dart Pro 1 380 heads

    Build Threads
    I have a fresh set of dart pro 1 380 heads that I had on a 565 but I need a new short block. Engine will be used in a 19’ Daytona jet boat and don’t mind putting race gas in it as it will have a 2-300 shot of nitrous also. I’m thinking 582-632 what do you think would work best?
