Final assembly and installation this week, tune end of week/next. Anyone wanna make a guess?

Here it is:
Ford 2V 4.6 block- now displacing 5.1L, 10.25c/r
TFS 185 TrackHeat heads
Crower ST3 cam (1800-6750)
KB 2.1L will be pullied down to make 10-11psi
75mmTB, Lightning MAF, etc...
Stock manifolds w/BBK Catted Mid-X

Through a Th3650
 
92 pump-
Street(able) car
Same short block w/same crower cam and stock PI heads made 460/470 @ 10lbs
So basically, it's now all about tuning for the TFS heads and a smaller pulley
 
It put down 477/460 with 10psi. Less than I hoped, but we did not change out the blower pulley, and the A/F R is safe sided at 11.4:1.
I'll scan the sheet and post it later this week.
 
I think the 2.1 as delivered can support about 500-525 at 14-16psi, without underdriving the main. I have heard of guys useing a bigger inlet, 2 3/4 Pulley, and 10%underdrive crank to get 600 to the wheels.

Yeah, I'll run it. I'm hoping for an easy mid-low 12's without having to stress too hard on the launch

Should be easily in the 11's even with a lousy 60 ft.
