Well, since the list is quiet, I'll post an update on my EFI conversion. I've got my MegaSquirt sitting on the transmission tunnel inside my car, and I wired up the power and RPM/vacuum inputs while the carb was still on to verify my power setup and that RPM was correct. Everything checked out.
I yanked the Performer RPM/Holley 750 off Monday night. I mock-assembled my TPI unit and set it on the block and put the distributor back in so I could see how everything fit. Took a bunch of pictures along the way. Not much clearance using a large-cap HEI. Tonight I started trimming the wires on the harness to the right length and adding the sensor connectors in. If I ever do one of these again, I'm gonna buy a factory harness and modify it, as I think that would probably save a bunch of time. RPM, TPS, Coolant, and Inlet-Air-Temp connections are all done. I still need to hook up the injector harnesses I put together, but after mocking it up, I might decide to re-do those. They didn't turn out as good as I had hoped. I'm aiming to have an orgranized, compact, low-profile wiring package. Next step is to yank the intake base off and have a machine-shop correct the middle four bolt holes since I bought an 87-up base, instead of an 85-86. And then I need to finish porting the plenum. Note sure how far I'm gonna go with that. I'm at least cleaning up the ridge behind the throttle-body openings. I need to pull the passenger side header so I can put an O2-bung in there and then wire up that sensor. Hopefully I'll get to that this weekend. -Dave
