Hi guys.
I am setting up a 347 Stroker motor in my 88 Cougar.
I actually had this motor running very strong in my Red Cougar.
Had to move it to Grey cougar because of many problems with the Red one unrelated to the engine.
So, today. We got the engine running [with carburetor spray]
Everything works great.
But the fuel pump in the grey is broken and even if it worked it would be sized for the stock 5.0 motor.
I remember that I put a higher GPH fuel pump in the Red when it was running. But can't remember what size it was.
I wasn't a whole lot bigger, just a little.
MY engine:
347 Stroker
93 Cobra OEM camshaft
93 Cobra OEM [the real deal] Manifold
24 lb injectors
Computer in the red has been modified for Mass Flow.
Throttle body is upsized a little bit. Sorry can't remember how big. My best memory is 65MM
As you can see I built the motor as a strong street motor Easy on idle and drive ability and no plans for drag strip racing but fun to drive.
When I had the ECU tuned on a dynamometer at a drag race shop it measured 350 HP at the wheels.
Two questions:
1. What is the stock GPH on the fuel pump?
2. What GPH fuel pump should I be using?

85lph is stock. Go with minimum a 155lph

Actually the SO pump is something like 60Lph, the HO & Turbo Coupes use the 85... Early Super Coupes use a 95... I have a 155 in mine, always had plenty of fuel even with spray...
