Now Brett will work his magic.. with this process we enlarge the plenum and shorten the runner.. Almost All mods Lengthen the runner on the plenum floor for best results on a single plane like that. Yours will want that too. Huge plenum short runners equals slow port velocity. Bad for fuel atomization and cylinder fill. Lengthen runner on the floor would be the worst thing you could do on an engine like this. Maybe on low RPM stuff that could work I just don't have that answer I don't really work with low RPM stuff. The stuff I am doing with this intake is not a guess at what will work I have a bunch of dyno and track data with intakes for high HP high RPM wedge head engines.

I think that intake would love to be dry on a injected engine..I did the same intake the same way.. cut it in half to do the porting and welded it back together... being dry it made more torque

I turned my W-9 up that high a few times trying to find more power.. it wasnt up there.. I found on my set up that 8200-8400 was the best EDIT I will say I had the wrong cam in it.. could have made at least another 100hp with a cam swap

Now Brett will work his magic.. with this process we enlarge the plenum and shorten the runner.. OK ,from the pics you didn't shorten the runners at all. You just added plenum. I thought that when you ssaid you would be shortening the runners, that you were going to remove/shorten those four walls dividing the runners. You Didn't and that's good. you left the runners as is. If you would of cut those out and shortend them, That's where the mistake would of been. But you Didn't, alls well. the runner length was shortened by 1/2 in because I was running spacers before..

L I have looked at the motor many times at the track and didn't notice until right now .. it looks like you guys are running a spacers.. by the looks of that package no one would ever guess it runs 8.0s. In a full body full interior car..

I don't know how much Bretts buddy charges for some of these weld jobs but boy can that guy lay down some weld. He must have one heck of a welding machine.

Bretts weave welding skills are at a MAD level for sure...
Shiloh yes we have used spacer because of the tall deck height of the block. Only one cast intake is made for those heads and not meant for the tall deck. The spacers will be gone this coming year as the deck height is changing significantly. You saw the current intake earlier this year. It is getting more changes again. The carb adapter is not gone as well now as it is part of the intake, we still run the shear plate and its adjustable length cones.
