Intake porting/blending

oldkimmer said
This will be on my RB Super Victor Max Wedge Port with 1250 Dominator carb. I’ll post pics of the mismatch. Idk the first thing about porting. I know I don’t want to be cutting or welding on/in it. More so looking for advice. Motor is a 543. 11-1 compression. .625 lift roller cam. Indy SR heads. I’m not sure the intake will be the choke point. The heads may not be enough to be able to feed the motor. Thanks. Kim

Looking at this again, I would run the spacer (its not really a spacer, it’s an anti-reversion/shear plate) and I’d take the plenum all the way out so that none of that rail around the outside of the plate is covered by the flange.

You may not see any HP on the dyno, but any time you can help direct the air/fuel where you want it and reduce exit losses at the carb is a good thing.
