427 SBC & 4L80e build

[72K5CSTDarkOlive]

I'm replacing the engine in trans in my 72 K5 and decided on a 427 Stroker mated to a 4L80e.

I'm using a local shop (Gromm Racing Heads) to build the engine and another local guy to build the 4L80e.

The parts for the build we are going to use are the following:

Block: New Dart SHP 400 Block w/350 Mains. 4.125 Bore, 2 pc rear main
Crankshaft: Dart 4340 Forged for Internal Balance
Pistons: Mahle Forged Pistons
Connecting Rods: SCAT Forged
COMP Custom Camshaft: TBD...I know that it will be around .600 Max lift and the duration will be somewhere in the ball park of 243-258 @ .050. The Lobe separation is 110-111.

COMP Full roller stainless steel 1.6 ratio
(EDITED) AFR 220 CC Eliminator heads, 2.10/1.6, 65 CC
(EDITED) Edelbrock Super Vic
MSD Pro Billet Distributor
(EDITED) Holley Sniper
Headers: Kooks 1 7/8" stainless steel

The Command Center will let me use my existing electric fuel pump and I am building a return line that will go back to gas tank through the sending unit.

The 4L80e will be updated with the 32 spline input shaft to connect to the 205 TCASE and he is building a billet tq converter using a 2500 stall.

These arrived this week and my builder is going to get going on this for me.


Updates as of 8/1/18: So I changed a few things on this build setup. I'm not going to use the FiTech and instead going with the Holley Sniper. I also wont be running their command center 2. To run the EFI I am using a Boyd Welding EFI tank that comes with a in-tank Aeromotive fuel pump.
