Item description

I built this 420 motor with Banks twin turbo, but I sold those.
It is EFI and I have an AEM ECU for it, but as it has been discontinued, I'd give you that for free.
I would suggest adding a Procharger so you can use the EFI manifold.

I had $25K into the motor all up but that doesn't matter anymore as $14,500 is a bargain
It has a Dart little M block
Howard Tracksmart Crankshaft
Oliver 6" Rods
Coated RaceTec Pistons 8.7:1
AFR 210cc Heads Inconel Ex Valves
Hydraulic Roller Camshaft 224/230 LSA

I made it coil on plug

Injector calculation
1000Hp @ 43psi 102.15 lbs/Hr 1074 cc/min

I also have a new ATI built 4L85E transmission built for it that I paid $7600 for.
I'll take $5000 for it.

I also have a 434 Dart little M block short block built for boost.
Howard Tracksmart crank, Compstar rods, thermal-coated Icon pistons.
Solid roller 4/7 swap camshaft.
I have $8000 in it.
I want $6000.
