I'm putting my 97 camaro LT1 into a 70 corvette. After looking into all the wiring harness options it seems easiest and best to convert to the ODBI setup. I will save money on the painless harness ($200) and avoid needing a new MAF ($50-$300)

Will all my 97 sensors work with the 93 ECM and harness? (Painless 60501)

I need a new optispark, do I need to order a 93 opti or does it matter?

Anything else I'm overlooking or alternative options let me know, thanks.

 

You CANNOT match 93 with any other LT1 year (94-97). 93 runs a complete different set up. You either need the 93 wiring and everything... or a 94-97 LT1 motor.
