holley ultra hp 750 installation on 351

[vector1]

purchased new in the matte black finish. had to then purchase the inlet because it has 9 3/4" c-c inlets which cost $100 from holley, not the same as barry grant or previous holleys, earls has them at a little more cost. installed on a fms crate engine 351 with afr185 heads which upped the compression to 9.5 using the z303 cam or the wildest they use i believe and rpm air gap intake.

finish was real nice and i couldn't see any flaws, everything is adjustable for those who can't leave well enough alone. i installed it without making any adjustments to see what their tune was. i had to drop the idle from about 1500 with the idle ez. the floats were set a little high initially with the sight glasses higher than normal the fuel level was still 2/3 of the way up the window, instructions say 1/2. there are sight glasses both sides so you can look completely through the bowls.

i did install the supplied main jet extensions in the rear bowl. i had to use an impact on one of the jets as it couldn't be removed by hand and the jet was chipping out even though i was using a hollow ground screw driver. doesn't take much to hold a jet in but can take a bit to get it out.

i dropped the float levels one complete turn and drove it in that condition without checking the level and other than that as above it drove real nice, no hesitation, stumble or similar problems. power was good, fires right up and idles nicely with clean crisp acceleration. hard braking and cornering didn't seem to effect it much. one complete turn of the float adjustment dropped the level to the bottom of the sight glass so i moved them back up 1/2 turn and will have to drive again to see if there is any effect.

real happy with this carbs performance so far and do not forsee any tuning, finish was also good. the finish on the carb just about matches the paint scheme on the car.
