A well done 13B Pport with very mild exhaust work should have 230 to 250
continuous at 7,500 RPM. Plan fuel pickups for a 45 degree climb angle.
If you only need 220 HP then the side port is quick and easy also.
Evening Lynn,
Thanks for the
comments. It's always a pleasure to hear numbers that are based on
experience.
I'm curious
about that 220 figure for the side port though. What vintage housings are
you talking about, and which form of porting? Surely that's not a
bridgeport on REW or Cosmo housings. What would you expect to see
with a mild/street port on a set of REW housings?
Thanks,
Rusty
