Carburetor Spacer?
Hey guys, installing a wieand 8012 on my 460 I am dropping in this weekend. My old intake was stock with EGR plate not used. My question is can I mount carburetor directly to intake or do I need to use a spacer? My carb. Is edlebrock 4 barrel

So in a sense, yes, you can mount direct, but you'll boil your fuel without some heat shielding. If that's not an option, go route B) and get a carb spacer. 1" phelonic/ plastic will do just fine.

That intake doesn't have the heat crossover under it, so heat shouldn't be a real issue. At least not in my experience. The volume on those intakes is huge, unless it's a high rpm deal I would stay away from a spacer if you can.

i have a Holley on a wieand and my carb linkage would not clear the carb base on the intake. So I could either dremel the intake or use a spacer. I use a 1 inch plastic spacer.

Ditto. Yes you can mount directly to that manifold, but a good 1" phenolic 4 hole spacer would help prevent fuel boil. Aluminum spacer won't help much, if any, with heat. Open spacer vs 4 hole spacer? I've tried both. 4 hole maintained good throttle response. Open spacer is more for high RPM operation. And an open spacer will probably cause a very lean condition that you'll have to tune for.
I haven't seen a down side to using a spacer. It gives clearance for throttle linkage. Gives a little more plenum volume which is like lengthening the intake runners, which gives better torque and throttle response. And again, it helps with heat.
