LS2 guess I normally hate the "guess my number" threads, but I'm stranded waiting for transmission parts so this is good filler.. Going in '67 chevelle.
Got a .010 over LS2, Autotec flat-tops (-3.3cc, makes ~10.5:1 CR), Wegner ported 243s (297/216 peak cfm), Vengence ported fast 92, stock 90mm DBW TB, COMP 54-457-11 cam (223/231 @ 050, .610/.617, 112LSA), 1-3/4" hooker super comp swap headers, 2.5" duals with x-pipe and Hooker aerochambers. Monster level 3 clutch with MN12 GTO 6 speed behind it, chevelle 3.73 12-bolt.
I know the cam is undersized, but I want kitty cat manners at 1800rpm highway speed. COMP says RPM range 1700-6800, seems like it should be rather torquey..
I'd be happy with 400/400, probably optimistic given the small stick huh.

That should be a fun street set-up for sure!! I also think your 400rwhp might be a bit moddest.. Should be very do-able for that set-up.. The one thing I might be kinda "iffy" on is the 2.5" exhaust comming off a 3" collector. Good luck, have fun with it & keep us posted with results.
