You can make what was a 8cylinder ecu run a 4 cylinder engine. buy a new air intake and water temp sensor and map sesnor, pretty much any new throttle body uses a tps sensor, and a distributor w/ a haul sender. dont really need anything else. if you go junkyard the whole way, i cant see it being more than $200.

Now your talking, $200.00 is my price range. LOL I was thinking the same way, but wasn’t sure if I was missing something or not. And considering that I want to put all this on a sbc, it should be even easier, right?
