Hello everyone, I need a little info on the holley 670 TBI unit. I have been serching through the threads and actually got overwhelmed. You rock, there is so much information on it. Anyway, I know that you have to modify the sensors in order to use the 454 TBI unit, but what about the holley 670 unit? I purchsed it witht he undrstanding that It's a direct bolt on. I just picked one up for $100 and want to put her on my ride. Thanks for the help, have a good one my friends!

you might have to modify the wiring, but not the sensors themselves.... that info is here as well...

search " iac wire swap" and i think that will find it. or just "IAC wire" - something like that, if you still cant find it, email me and i've got all the info, somewhere
