5.2 5.9 magnum EFI plug and play harnesses

sorry, i overlooked half of your question. the computer does require a crank sensor, which mounts between the block and transmission using two bolts on the block. To make this work with a 4 speed you would have to use a flywheel made for a dodge truck with a magnum engine, you can't use an LA flywheel. You'd have to use a magnum flywheel anyway though, as the balance is a bit different. A factory magnum flywheel is 143 tooth, so you'd need to make sure your bellhousing can handle a 143 tooth flywheel. that's where it can get tricky. I am not aware of (but that doesnt mean it doesnt exist) a small block 143 tooth bellhousing. I believe Lakewood make SFI approved ones, but quit last year, so youd be left to old stock or used ones. Other ideas I have heard guys do (but havent seen it personally) is to take the 143 tooth flywheel to a machine shop and have them lathe the ring gear off and weld on a 130 tooth gear. I've seen that info online, but never in person. I guess you could also take a MP magnum flywheel to your machine shop and have them cut the crank sensor "windows" into it.


so the answer is....maybe

the computer, engine, and harness don't care what transmission youre using. the hangup is finding a small block bellhousing that can accomodate a 143 tooth flywheel. I'll look into it more and get back....

thanks!
