Is a 1 1/2" Carb spacer too big?

What is the engine setup? I would really advise against it unless you're going to be rocking some HIGH RPMs because that much spacer is going to push your power band up into the high revs and kill your bottom end. I used to run a 1 inch and i had installed it with my old Stealth intake and 650 double pumper, and i never realised how it was killing performance until i took it off on a hunch one day...it was literally like day and night, and since i didn't have the heads to take advantage of high RPMs it was a win win situation.

I would say just get a smaller diameter breather. I've also seen valve covers that match that breather lid...those would be sweet but man i'd hate to have to polish them!


Hey as a matter of fact i just remembered, i went from 14.50s to 14.20s when i ditched my spacer, and that's still blowing the tires off.

If you only need enough space to get the plug wires on just drill a new hole on the lower part of the cleaner about 1/4" or so back. Then get a threaded shaft tack welded to the original hole so that the center hole in the lid can still be used. I have seen this done before. If you do it right you wont be able to tell that anything was done.

Sounds like a pretty killer setup. I might have opted for a Vic Jr over the Airgap, but the Airgap is a fantastic intake as well. The Stage II goes great with the Vic Jr. You're really gonna want some gears though...carbed cars especially need a matched gear to really maximize the jetting/cam/air flow setup. It should be a pretty fun motor though.
