Just bought a 92 Z28 TPi, <!--StartFragment --> Ported manifold and plenum, everything is gasket matched, lower manifold was setup with inserts so it will bolt to old and new heads, 24lb injectors, BBK adjustable fuel regulator, BBK air foil, fuel rails, water neck, sensors.
Now my problem, did not get the harness or ecm, so I'm searching for how to make this jewel work in my 69 GMC Stroker project.
Fresh engine is a mild 383. Right now it's driving a TH400 and Dana 60 4.10.
Project plan is to install a 86 Vette 700R4 and a F**d 9" posi rear. Right now the gear is 3.0.

I bought the TPi Swappers Guide and downloaded the HR "TPi Tunin" article, but still have more questions than answers.

I've looked at several options from factory harness and ecm to Painless harness and modified/emulator ecm, to Accel Gen 6 harness and dos based ecm.

I was steered to this site by my friends at 67-72 Chevy Trucks.

Hoping to find some suggestions. guidance or parts here.

Thanks and hope I have not broken any protocols.
