396 LT4, what do you guys think... I've got a 396 LT4, and would like some input from you guys as to how you think it will perform. Here are the specs for it:
LT1 block with 4 bolt splayed billet steel main caps and ARP main studs
Callies Racemaster 4340 3.875" stroke crank.
Oliver billet steel 5.85" rods
Ross 11 to 1 nitrous pistons.
Childs and Albert heavy duty wrist pins.
Calico coated main, rod and cam bearings
Childs and Albert Zero gap rings with G-2000 top rings ring set.
AFR 227 LT4 heads with AFR's competition fully cnc ported, 2.10 int. 1.60 ex. Ti. retainers with roller cam springs.
Jesel competition series shaft rocker system not the cheaper SS series. 1.6 ratio
Comp custom solid roller cam, .254 Int .266 Ex at .050 lift and .622 Int .638 Ex. valve lift with 1.6rr's, and 112 LSA
Comp roller lifters
Comp pushrods
LT4 H/D timing chain
Meziere elec. water pump
ATI balancer
GM motorsports Pontiac valve covers
Cometic MLS head gaskets
ARP head studs
LT4 intake fully ported and port matched to heads by AFR setup to run a mono blade t-body
ASM mono blade t-body
Stefs fabricated aluminum pan
Melling hi volume oil pump
Dynatech 1 3/4 inch long tube headers, with merge collectors
What do you guys think this engine combo will produce, going through a T-56 tranny, built to handle the power, and a 9-inch rear with 3.73 gears? Any comments are welcome as well.

That beast needs to breath, but I think it'll be chocked with that intake. Maybe if you went with a single plane intake, a sheet metal or modify the stocker to increase the planum volume.
Good luck

It sounds like a beast, I'm doing a 398 LT1 myself but Hydraulic Roller. Trick Flow heads worked by Loyd Elliott, LT4 Intake Port matched, Cam by Loyd Elliott and Bret Bauer, Callies DragonSlayer 3.875 Crank, Eagle H-Beam Rods.
Arizona Speed and Marine 58mm throttle body, Crane 1.6 Roller Rockers.
Heads are 2.08, 1.625 valves.
