Wouldnt a weind be good to go with since its not plastic? Alum works great so I dont see a problem with it.
DSMs,Supras,Mustangs etc all use alum intake manifolds....

I would keep the compression at 9.5-1 to 10-1 and run the D1.Expecially with that small cam.The boost will be easier to keep in check with HP goals in the low 800hp.
The reason I mention this is because we just pulled apart a motor just like the one you want to build. -346,AFR 225's,224 Cam,F1 with a big pulley still making 16lbs at 6200rpm,18lbs at 6800rpm. The main bearing's are wiped,piston skirts wrecked,and kept lifting the heads. All these hassle's for the F1 ,the previous D1 made more HP in the midrange and never a problem with it

its the design itself that keeps people away from that one... it doesnt flow as well as a LS6.
plus theres one drawback to most alum intakes.... its hard to cast alum as accurately as you can mold plastic... so alum intakes tend to need some cleanup work to be perfect, meanwhile, plastic intakes can be closer from the start.

What if you went with a 408 with a F1? Would that be a better set up for that size charger, or does the main problems come in factor when you are at high boost.

You'll also have to figure out how to fit an air filter on there if you go F1, let alone the bigger F1C or F1R.
I don't remember if you'll be able to keep the ac or not. But even if you do, there's a good chance you'll run into overheating problems due to everything being crammed together in such a small space...fmic, hot ac condenser, radiator moved forward (maybe even a thicker aftermarket radiator), and larger blower. You may be able to fit a 2nd radiator fan, but even then on hot humid days (95+) it will get in the 220's.

My car made 840 rwhp on a 385cid motor with a F1 head unit, 16 rib pulleys and FMIC. The car has 5 year old ls1 heads that flow horrible numbers and a cam that was chosen when it was a d1sc making 8 lbs of boost.
The car will now get a cog set up, AFR heads and a custom cam. plus a few small changes. Im expecting close to 900 rwhp if not a little more.

I took the air filter off and had a screen made. I didnt drive the car in conditions that put my motor at risk. Zero problems with my fast at 18-20lbs/boost
