Changing to fuel injected, maybe!

I have a nice 360 mopar,less carb, and I have a 4.3 chevy that is complete. My question is, what all would I need to convert my mopar to fuel injected, by using all of my chevy 4.3? Advise, thanks, Dana

You would need the injectors from a 350 Chevy (the 4.3 throttle body is otherwise the same), all the sensors, the wire harness, the ECU, the fuel pump (15-20 PSI for TBI, not the more common 40+ PSI), an adapter plate to bolt the throttle body to your intake, an electronic distributor that uses the HEI module, and a custom PROM for your application.

x2, but there is an alternative to the custom tune. When you look at the limitations of the factory GM TBI ECM, there can be a lot of trial and error involved with custom TBI swaps, especially on to a non- GM engine. There is a guy who takes your computer, and does away with the chip(prom) setup, and uses his own hardware and program to make a computer that learns as you drive.

I am going this route with my scratch build because when I added up the cost of sending and resending a few times the chip + the $50 each time to reflash, I am not spending that much more and getting a way better product. His website is www.dynamicefi.com. I would send him an email. He always got back to me pretty quick when I had a question.

Hope that helps,

Josh

Oh yeah, make sure you get the right fuel pump. I think if I remember right 94 and 95 small block v8 trucks actually had higher psi than the usual 15psi and I think the big block trucks may also have had a higher psi also but not sure on that one. My point being don't just get one that is "for TBI", cause there were a couple of different ones. The v6 and l4 were all 15 psi as far as I know
