I have a customer Im building a 46-ish willies flat fender for and he purchased a Summit crate motor for it. SBC, vortec heads, dual plane intake etc... (He's getting me specs on the motor) I talked him into going EFI vs. carb and he agreed, we discussed options and decided to do a TBI conversion using all GM parts. Got a 93 454 throttle body/ecm and all the sensors, dist, coil, harness etc... Plan was I would install, build the harness and tune the stock GM ecu and be done.
Primary reason for using all GM tbi was reliable, easy to fix, cheap avail parts should he be out of town and breaks down, he should be able to find someone familiar with tbi for help. Was going to set him up with another spare ecu, module, coil, fuel pump and wiring diagram for his trail box as well... He wants to be able to drive this thing to Moab from Fresno so this is why I suggested what I did.
TODAY he calls and says he talked to Summit and they suggested he buy a "Retrotek-3" as its "bolt-on and go" and he wouldnt need any tuning or a laptop etc... > They originally told him that what I had planned he would have to change the cam in his motor to do... (still dont know what cam nor why they told him this) ???
Sooooo looks like I get to try my hand at Retrotek EFI.... Any words of advise? Do these things work the ign also?
