Thread: is a 750 holley to much carb for a 350

Tweet

I have a Holley 3310-3 which is a 750 cfm carb on the Willys. The motor is an Edelbrock rpm 350 with the rpm air gap intake.

After a bit a swapping shooters and pump cams it runs great. We are working with the vac secondary now. We can get it to sort of lay down or run out of air by not opening with the stiff spring. By changing the secondary springs in steps we have it so you can't really feel the secondary come on. Actually if you feel them you are experiencing a bog then a surge. It helps to have ear plugs so you don't equate the carb noise with additional power. This is a great carb for almost any normal engine...if there is such a thing. I had the early version 3310 on my 395 375 hp Chevelle and it worked great back then too.

The next step will be some fine tuning to get the A/F ration exact. Not going to worry about that untill spring however.

I dont think it is i say just tune it and mess aroudn with it until you get it setup right because I have a 350 bored .30 over and i have an edelbrock 750 on it

Ran a three deuce set up with 3 rochester carbs with no progressive linkeage and when I open them all up at the same time my engine bogged down for a couple of seconds. That was a total of 750CFM in a 305. Went to progressive linkeage and it ran without any hesitation. Changed over to a 600 cfm carb and thats what my engine feels better at. I even tried a 650 with the same results but crappy mileage, so the 600 is on for good.

Anyone notice that the original poster didn't even acknowledge the answers, and hasn't posted in more than a year? I doubt that we're helping him much . . .
