Hey Guys,
I bought a 750 VS holley off a member here. Its choke horn reads
3878261-EH
LIST 3310
0743

The jets are 72/76,would these be ok? I am currently running a Q-jet with 72 primaries, G hanger and DA rods. Works OK...

My motor specs are
355 8:1 compression
Crower 00230 cam, 214/224 .450/.470
Draw through turbo, rajay 301E10 pushing 7 pounds of boost
Mallory 685 boost ignition box and procomp HEI, msd wires

4 speed
3.42 gears.

Thanks Guys.

I just did a quick search of the web, and the number 3878261-EH is a '65 z16 Chevelle 396/425hp 4 speed carb. But the date code looks like a service replacement.

niiiiiceeeee. Does anyone else know anything about this carb?

go to holley website click on tech service then click on tech library then under carbs click on carb numerical listing and scroll down till you get to your list number.it will tell you every thing on that carb.

Its a 750cfm, and that jetting is probably pretty close, although I used a 70 primary with a similar setup.

LT - I would just hang on to that carb and let Damon work on the Q-Jet. :)

Thats a good idea corky. Ill PM him and see what he says.
