opcorn:....... Holley vs Q-jet is like Volvo vs Mercruiser or oil and fuel threads. They both are basically glorified toilets that get fuel from the tank to the combustion chambers.
first off, in 1992, the 260hp GM 350 mad 260hp at the flywheel. so add about 15% (parasitic loss) to that and you get a small block with 300hp at the crank. a 330hp reman is only 10% more
the same carb that fed the old motor should feed the motor just fine, however based on post #6, Chris hit the nail on the head with his answers in post #7
NHGuy also hit on a point in post #9. What motor was built. just saying a reman 350 is like saying I made soup. What ingredients, prep, and proceedures is what determines the kind of soup. in this case, what kind of motor was built?
an auto parts store reman is NOT a marine motor. wrong head gaskets, wrong cam, wrong core plugs. A marine motor is closer to a dump truck motor built to haul a load up a 10% grade while driving in sand.
to expand on a few of the posts, my suggestion is as follows:
first - get the build sheet of the motor. specifically the cam specs, piston specs, static compression ratio and rocker arm ratios
second - post the information here
third - perform a compression test and leak down test
fourth - verify base timing and perform the ignition tests
fifth - post results here.
