Need a recommendation on a fuel pump....

For a 416 small block, 600 plus hp mechanical pump...any info would be appreciated, also no mods...thanks

C & S Specialties has them but arent cheap, its a 6 valve mechanical i think you can also get a chevy 6 valve and a mopar and swap the arms.

Holley mechanical will do the trick. We run one on my kids buit 360 and on both our BBs.Mine feeds my 550 hp 440 with a 1050 Dominator.Never runs out of fuel.Rocky

Ihave been using a Clay Smith for about 10 yrs. Great pump and zero problems.
