73 dart hemi swap help

PART 2


Next question, Fuel system if EFI, 3/8 line needing 58 PSI, your chioce in-tank or not for the pump, and fuel regulation. Cheapest is out of tank, quietest and most road worthy is in tank... rockvalleyauto or someplace like taht sells a drop in unit that welds into the factory tank, thats what I used. speedway motors sells a LT1 swap pump and connectors that is a good option too. Most guys use a 99 corvette fuel filter, it has a built in regulator at 58 PSI, and takes care of the return line out too... multiple threads about this set-up too..

The next engine hurdle is accessories, the truck timing cover fits them easily, the car cover puts the ALT really close to the passenger frame rail, I trimmed the frame lip for mine to fit. Most delete power steering, however TTI says they have headers for the borgensen power box, NOT factory box... The above companies make PS delete stuff for belt routing. The AC is doable, but I dont know much about that. The radiator, hoses, elec fan and remote oil filter are all little headaches...

Transmission: The Hemi bolts to a SB trans, you just need a different flex plate or flywheel available from mopar or mancini. I would plan on beefing up a 904 to handle the power. The rest is all how you wanna do it, parts are available from multiple vendors. The 545RFE from the 2wd Hemi trucks works great for the swap and can use the factory ECU, however major floor surgery is required.The factory hemi car trans are really not usable due to programming problems with ABS and VSS sensors and the ECUs. As far as 5spd, Id look at passions 855OD, the R154 "supra trans" or a T56. Theres threads about all of these options, all excepts the passion trans will require floor mods. I run a 727 for now, and will swap to a OD (200r4) next yr hopefully.

Not sure which rear you have, I'd say most guys swap to a 8.75, I'm sure a 8.25 could be made to handle the power, I doubt a 7.25 would handle any abuse at all. But I've never ran anything but a 8.75, so I know little about the others...


Thats the basics, there is so much info on FABO, it is literally the BEST place for these swaps, lots of reading, and slowly build what ya can get your hands on.
