The front mounted throttle body type intakes don't deprive the rear cylinders of air,the air moving through the intake hits the back wall and forces more into those cylinders, causing them to run slightly lean.
What was suggested was not to run a larger injector in the rears, but to flow a set of injectors, and use the two that flow the most out of the group to supply slightly more fuel the rear cylinders, lessening the possibility of losing #7 due to a lean condition.

Maybe they should taper down as they go rearward instead of having a back wall.........

Too bad a carb intake won't fit under the cowl/hood of a Trans Am, and flow well with an elbo.........I'd love to do that.

Well, I just got done deciding, with Richards help, to go with the Brodix heads and his CNC program.....should be some nice 400+cfm heads. Gonna go with 11.5:1 cr and 441ci. Cam, we have not chosen one yet, but its gonna be medium to heavy aggressive.
I'm pretty sure a sheet metal will be best, but I don't know if a Marcella is any better than any other sheet metal intake. And since now I have to have a custom one done no matter who does it, because I need it to fit under the cowl and factory hood of my WS6.....I can have anyone make one, even my friend in his fabrication shop for probably under $1,000. He has an old Wilson sheet metal intake he's going to just modify to fit under my cowl/hood. He'll just take measurements of my cowl/hood area and make it work. Should be easy for him to do. Just have to taper the thing down as it moves rearward.
BUT.....I just got word I might be leaving for the Middle East early January, my job will be 30 days "on" and 30 days "off" rotating annual schedule. So I'll be back from my first rotation with a completed engine sometime in February with 30 days off to get it in the car. But I doubt the intake will be done. I might just get a Mamo Fast 102mm on order.....
We'll see.

i had a hard time deciding on heads as well, but i figured id save another 1k and run the tsp heads. the brodix, ls7x (both from wcch) and mast heads were all 3300+. the only other cheaper heads i could find were the ls7x from cbm motorsports. my budget was blown apart with a sleeved block and a sheetmetal intake.

Its a Wilson, it was going to be used on a LS7 air-boat engine. The plenum is tall as hell, way more than any other I've ever seen on an LSx style engine. It looks like we just need to lower the top of it and taper it down maybe 1.5 - 2 inches. From a fabrication standpoint, he says it'll be a cake walk because all it is is removing some side wall at the proper angle all the way back, laying the top piece back down to meet those sides then trim off the excess in the back that sticks over beyond the rear wall of the intake. He's a master at welding so its going to look perfect, he does welding artwork.....
Only thing he never did before is drill the holes for the Direct Port nitrous/fuel nozzles, so I'll have to find someone around here to do that.
I'm probably going to end up having it tuned with the Mamo FAST 102mm....then when this thing is done we'll go see what it can do and retune it for the Wilson.
I guess I can flow test the Wilson after its altered with the 105mm TB to see how each runner breathes......if its all even I'm good to go, right????

So I gotta let the bastard breath. 105mm tb, 104mm Lid, sheet metal intake. Might use something other than a lid....we'll see.
