Squirter size???

Not just Mopar's, but with any moderate street style small block in the (300/400hp) range.......I generally ended up with a #28 for dual planes, and a #31 for single planes using a 750 DP or a 750/780 Vac holley.

Obviously every combo will want it's own thing, but these are just average numbers, w/o spacers, i ran across tuning cars over the years.


P.S. I just realized you may have been talking both sides instead of just the primaries.....
For the secd. side, mostly the #31 worked well there also, although a #35 worked better on a few stouter, single plane cars that had some gear and a converter that flashed in the 3000/3500 range.


P.S.S. If the previously mentioned numbers still don't work, it's usually a timing issue....meaning not enough, or you may get into playing with pump cams, which I always avoided if possible on a moderate street engine that didn't have a huge plenum intake or a big spacer.
