Thread: Blower and Mechanical Fuel Pump

Tweet

I am going to have the shop build my first, blower 383. This whole engine will be built around "street driving" so compression, cam, carbs etc will be adjusted for the street.

My question to you guys- The shop is really wanting me to use an electric fuel pump opposed to mechanical! I am not crazy about this. Is anyone running a blower with a mechanical pump and has experience? Again, this is a street driven car.

I have a tunnel ram with (2) Edelbrock 500 cfm carbs on my mildley built 350, Performer RPM Heads and cam package on it now that I am driving on the street and it runs GREAT with my mechanical pump!

Looking for some feedback.

Mines a street driven Holley 420 Mega blown 355. Two Speed demon mech. 650s. Rev limiter at 5500 running a Holley 110 gph cam driven pump....carbs never beg for fuel.....

Thanks you. Nice Vette!!!!!!!!!!1

I talked to the Edlebrock rep @ the NSRA Ky nationals. You gotta watch fuel pressure. Okay to run THEIR pumps with out fuel regs. Still you should monitor with fuel gauge on engine to make sure you do not create more problems with too much pressure. I know you are not considering this but he told me even the stock oem feul pump should be regulated. They have seen 9# on some!
