Nathan;
BP Northwest carries a pretty complete line of shortened pushrods and, I seem to
recall, I got mine fairly cheap... and, they have about any length you could
need, in stock. I also got my Piper 270 from them, sending them my stock cam
(had three bad lobes) to offset the core charge. BPNW sells cams, lifters, valve
guides, valve springs, AE pistons, etc. at pretty reasonable prices and again,
with most everything in stock (unlike many other suppliers whose names I won't
drop).
