I just got my conversion running. (46 chevy 3/4 ton)
261
t5 tranny (from firebird with a chevy tail. No problems with the clutch, slipped right in without grinding the input shaft, had the higher spline count)

4.10 rear end

changed intake manifold to one from jim carter that fits a holly carb,

hei ignition
fenton headers to fit the intake better.
fired up with less than 2 cranks.
a bit loud going to the muffler shop but boyu was it fun.

Would do it again in a heart beat.
