What power level is the factory 454 Mag (carb) fuel pump good for?

I was going to upgrade to a Holley 130gph mechanical pump to support my blower, but that would save me $150 if I didn't have to switch. Blower is a 250 with twin 850 Nickerson's.

Thanks.

Not enough, that's the one place I wouldn't skimp. I believe 80-100gph.

That's what my gut was telling me.

Good info regarding what the factory pump is good for, too.

I was told the stock fuel system is good for 600 hp, I'm sure you will be well over that.

That's the hope anyway!!

The 525sc used the belt driven merc fuel pump to supply the fuel to the single 1050 dominator on the 177. The 600sc, used the same merc fuel pump, to supply the 420 blower with twin 700 carbs. The 800 and 900sc used a holley 6 valve internally regulated block mounted holley pump. I use those pumps on my engines feeding twin 850 holleys on a 420 megablower. Holley no longer makes them.

For years guys have blamed fuel pumps for being the culprit of their fuel supply problems. Many times, it wasnt the pump that was the problem, it was the rigging. Like the pickup in the tank, line diameter, restrictive fittings, poor flowing filters, and things of that nature.

Tom, if you have Mark IV blocks, I would go with this pump and be done with it. They are much better than the new non 6 valve crappy 130gph holley pumps out today.

Google Baker engineering. Just got two pumps from them this past august, they have 1/2 ports.

Yup. The link I posted was for the baker pump, just on teagues site.

Might as well support a sponsor ( I like Teague)

Their pump is a nice, well built piece.
