in my case the underhood wiring was a butchered mess to be "nice" about it so I couldnt wait to gut the wiring in the engine compartment and start fresh with a "new" wiring harness from a junkyard truck. and since the junkyard truck was already a 4 pin ECU harness, I had no desire to add the wiring back in for the Lean Burn.
I might try an HEI swap some day just to compare, I can get all I would need from the local boneyard for practically free.... but for now I aint fixing what aint broke.
