All great info, thanks. Guess I'll go 2 line and canister then. I'll use this diagram: www.nastyz28.com/tech/e-fuelsys.jpg The 350 is bored (pretty sure he said .30 over, I don't know the crank) has shorty headers, and the performer intake manifold. Perhaps I should go holley to avoid the low psi issue? It has a really old holley 600 on it now. I'm hoping to reuse the old clips to attach the line, I don't suppose the new lines will come with any?
