On some of these BIG manifolds like Bret Miller makes, most guys run at least a 1" open under a 4-hole tapered for best results and Jeff Saucier on here just made 817 hp and 500 something tq w/his little 418 w/this combo iirc with one of my 1150ish blp billet Dommy's and many others run similar spacer combos some up to 4"......

Doesn't take much of a dam. 16th" high, use epoxy. Can be removed easily if not satisfied with the results.

[quote=B1MAXX]Not doubting any of that, but an open spacer would be quickie. I have a flow bench but I'm not sure how you would set up a manifold to pull from all 8 at the same time
Most v-8 manifolds I set up pulling out of the two intake runners that set side by side, and use duct tape to block off all the other runners. It is not perfect, but after you do all of them and document flow and velocities, it gives you a better idea of what is going on. I did a couple cast iron dual plane intakes for a pulling truck class that required the OEM manifold, no welding, just work on a milling machine and carbides, they turned out very good. both my buddies had their engines torn down by competitors, who had to post money to have it performed. Got ya!, thanks

I've used the Wilson reversion 1.5 inch spacer on all my stroker 400 motors with both the Indy 400-3 early and late intakes, none of them had the interior work done like yours is now. I have seen 150 degree difference in the EGT on #2 and #7 cylinder on several Indy 440-3 and maybe one stock late model 400-3 with no spacer on two different brand engine dynos I had Bob George racing modified one 400-3 intake for me but I don't remember now if it was a early or late model casting or not now
