I bought a short block from RW, rules say "must run mechanical fuel pump". I bought the Carter fp from Speedway and everything was great. Since I have traded off that big pump to a friend that runs mod mini vs my stock mini. I bought a stock (Pinto) mech pump that wouldn't work, neither did the upside down Ranger pump. I believe I have a late model block. There is a 3 bolt pattern on the block, on top of the aux shaft. The block on my racecar has 2 front holes and the rear hole is outboard toward the fuel pump. (Late model where that 3 bolt pattern was used for p.s. pump bracket) I have a bunch of other blocks and the rear hole is inboard toward the head (early model where that 3 bolt pattern was used for alt bracket). There is extra meat cast into the block below that outboard bolt hole. The Carter fuel pump clears that meat or boss because of the arm profile, no stock pump I have found does. The boss holds the arm down, never letting it reach the cam lobe. Is there a stock pump that will clear the boss??? I don't want to go into the motor and machine/grind off the boss OR buy ANOTHER high dollar pump that I don't need.
