Phil,
Rule of thumb from a long time ago is go up no more than two size or ' risk '
upsetting a/f numbers. I slipped a 48 bowl between 97 air horn and base and used #50
jets and a #60 pv to run my '32 p/up...286 cu in....it runs wicked good. I've got some
48 bowls..get back to me at
[email protected] if you wish.
