First off I got a 509 hoping for 750hp going with 8/71 it is getting freshened up right now by DPME. I got dual holley dominator carbs, I am running baker 15psi mechanical fuel pump looking for best possible way to plumb it and cleanest. I know I need a bypass regulator looking for which one everybody is using?
Second I only have room for a 2 groove crank pulley after my 8mm blower pulley is this possible to run power steering pump an alternator and sea pump. This motor is going in a 95 American offshore 2600
Thanks any help would be appreciated.

i had a 26 ao -540 with 8.71 and a superchiller just north of 900 hp.i ran a 3 groove pulley.just had to grind a little glass right in front of the blower pulley.even without a chiller you should have no problem meeting your hp goal.hardin marine sells a really nice fuel log and aeromotive has a bypass regulator.with 750 hp you will see close to 100 mph.

Can you run your fuel bypass to the fuel filter housing instead of going back to the fuel tank? Fuel filter is before fuel pump.

i disagree,i recently did a 522 build with 1050 carbs that made just shy of 1000 hp.you can,t really over carb a blown engine but you can easily under carb one.
