engine specs.
-305 (hot cam, headers, roller rockers etc.)
-'86 TPI, ecm 1227165, no harness (missing MAF sensor also)
-TH350 tranny

the tpi is off an '86 F-body 305
i'm switching over to the MAP system as the engine is a ways from stock and the vehicle is nowhere near stock

whats a good, easily findable ecm to look for? (i'll need to reburn it to match my engine/vehicle)

 

The 1227730 is the MAP TPI ecm used in thirdgens ('90-'92). It was also used in lots of other cars (even six cyls, I think). The '727 is a weather-resistant underhood version of the '730 (used in the vettes). You might want to check this out:

If you haven't already, I'd look at the stickies in the DIY-PROM board. Also, I believe there's an article on how to convert from MAF to MAP on the main page, that might help you a bit.

HTH.
