Larry- Why do you want to replace your
carb? Having built a few Chevy sixes, stock to wild, and spent some time
with the gurus at Clifford Performance, it is possible to adapt other carbs to
the stock manifold, but not worth it for performance purposes. The most
you'll gain is about 5%. I've put (gag) pinto 2bbl carbs on with the
thought of better driveablilty, but actual improvement was little, especially
for the amount of adapting involved. I've also seen 350 cfm Holley 2bbls
used, same scenerio, but they are not progressive, so it makes throttle response
worse. I've had best success on built up engines with either Clifford's 4
bbl manifold and a 390 Holley, or my first home-made setup, 3 stock 1 bbl carbs
each on their own individual runner to the intake port. I had a bunch of
time in that setup, and tuning was a nightmare, but it ran like a scalded ape
from about 4000 rpm up.......until I ventilated the block. Not of much use
in your truck anyway.
