carb spacers - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Question I will be getting a new carb soon (road demon) Thinking of running a 1/2 inch phenolic spacer 4 hole. My reasons are two fold, phenolic to stop so much heat transfer to carb 4 hole to get more low end power. I am running the rpm air gap intake from edelbrock. Any thoughts on this worth the trouble and expense or worth a try?

Thanks

Phenolic spacers are well worth the money, we have been using them on race engines for years and I can say with great success.

I've got a 1" phenolic 4 hole spacer for in between my edelbrock performer carb and intake. I've heard lots of good things, so I figure I'll try it.

Phenolic spacers are a definate must have.

Has anyone tried a Swirl Torque spacer? I've seen them in Summit for like $30 and was considering one.

Also is it true the 4 hole is better for low end and open better for top end?

Ole Blue 68 · 04-21-2006, 06:27 PM

I think the 4 hole is called a Swirl Torque. At least that's what I've seen them called.

It holds true for intakes so I would think it would be the same for a spacer.

Some four holes are swirl and some are smooth.

I wonder if it really makes a difference...

Hard to say, in theory it would buuuuttt. In real world hard to say. I will stick with noswirl mainly because of the price difference.

Put mine on in about 15 min. 4 hole between a stealth and a 750 performer. I like the difference. Pulls hard in the bottom, had 4500# on the trailer and really didn't shift that much going up mild hills. Added about 20' more of burn out.
