I might have to steal my manifolds from my 383 as they already have a O2 sensor spacer in them.

Harness is about $400.

Im to the point where I can have a harness built for my Holley HP ECU. Then I can use that rather than the mefi 1 ECU. I'd have total control plus datalogging and I would be able to at least monitor...

Thanks for your input. I figured it was running an old outdated file. Probably the original one as far as I know.

I have the Holley HP on my 383. I'd put that Holley HP on my 350 but all the sensors are different from the 350. Kind of like first generation GM sensors versus 2nd generation GM sensors.
