Tech Question
David Gutchess, Nashville, MI, 1991 Dodge W250 318
I have a gutless 1991 Dodge 3/4 Ton 4x4 pickup. I want to do an engine swap I have a fresh 1979 360 that I want to install. My question is will my TBI off my 318 work on the 360, being a higher displacement? And if so were do I get rebuild kits for the throttle body? Thank you for your time I will be waiting.
Dave-
Will it "work", i.e, start and run: Yes. Will it work right? No. 360s had a different intake manifold and throttle body / injector.
The right way to do this is to find a junkyard '91 360, take the TBI, manifold setup, and computer. Then you'll have, effectively, a totally stock '91 360 engine.
Sleazy "out" number one is to keep the 318 stuff and install an adjustble fuel pressure regulator, increasing the fuel pressure to 'cover' the added displacement. Requires a chassis dyno and wide-range O2 sensor to tune passably.
Sleazy "out" number 2: put a carburetor on it.
For truck use, it's really hard to beat a complete '93-up 360 Magnum (SMPI), but that's a whole other story!
