I'm running a 383 stroker with a D-1 ProCharge at 14 lbs of boost. The question I have is whats the best size of primmary tube on the header.
Will 1-1/2 tube with a 2-1/2 collecter work. Thanks for any help.

1-1/2" sized primaries are small for a 383, with or without a blower.
For a 383, you should be considering 1-5/8" sized headers as a minimum. Ideally, you'd be much better off with 1-3/4"; if you're making more than 500hp, then go with 1-7/8" headers.
