Piker Porting (Intake Manifolds)
Here’s a Victor 340 I’ve been working on. Addressing the actual plenum opening, to closely match the carb gasket, radiusing the flanges into the runner roofs, fixing the divider leading edges, etc. I scribe for the roof radius’s for consistency on all runners.
Use Harbor Freight professional air grinder and TTC & T&O double cut burrs (1/2” oval, 3/8” trees and a 3/8” straight/radius end) Rough everything in, go over it again, sand roll/smooth out afterwards
