lwebb Posted January 9, 2015 Report Posted January 9, 2015 My apologies if there is a post out there dealing with this but I couldn’t find it if there is one. Lots of posts on other engine swaps but couldn’t find the 5.7. I have a 5.7 HEMI with 5 speed transmission I want to put into my 49 p18 4 door. I already have front disk brakes so the fat man conversion for helping with the steering box isn’t an option. Has anyone done this? What all am I looking at for major problems in getting it to fit? Thanks Lanny Quote
Plymouthy Adams Posted January 9, 2015 Report Posted January 9, 2015 I do not think you will find a step by step procedure for the transfer...as basic mechanics are involved and fabrication skill and special equipment needed...first thing is do you have the space tool time and equipment on hand to attempt said conversion. It is quite a lengthy process and once the cut is made there is usally no turning back...if you have done this work before as you know there is nothing hard about this at all..just a very orderly set of step to achieve ones goal. Measure measure measure is the key...and many here that have transferred the modern set up has reverted to carburation..what a shame but again one does what one must based on their own experiences...not really cutting you short, but only you can decide if you are up tot he task...very little step by step or pain by number on older Mopar retros are out there...basically I do not see any real complications given you already have settled the score on steering and brakes..one will have to install swing pedals for the brake/clutch..I did that on my 48...not any problem at all..

lwebb Posted January 10, 2015 Author Report Posted January 10, 2015 Hey Plymouthy thanks for the reply. Sorry, I’ve posted this on a couple other forums and it was suggested I also post it here. but I forgot the pre-ramble: Some background. I will not be able to do the big work myself, old hands, no shop, lack of knowledge but I found a shop that does restoration and resto mods, beautiful work and can apparently do anything but I was trying to help with the research as they mostly do Chev GM and Ford. He has a 5.7 HEMI with transmission sitting in a 50 Plymouth Wagon. It’s not connected and I found out the wagon belongs to a friend I hadn’t seen in years. My friend has decided he wants to put in a bigger HEMI and will sell me the 5.7 and transmission for $2,500. He knew the owner of the truck it came out of. It has less that 40,000 miles. My friend retired from owning an independent auto parts store for 30 years or more that dealt mostly with shops and dealers and picked the 5.7 up 7 or 8 years ago and it's sat in his garage. So he know cars and motors. The wagon the 5.7 is sitting in has been drastically modified, chopped and lowered so it won’t be exactly the same install in my stock 49. Except for underneath the hood etc. I want to keep the 49 as original as possible. So comments like "one will have to install swing pedals for the brake/clutch" are the kind of things I need to hear. What are swing pedals? Are their kits to do that? From what the shop has told me it will need to have an electric fan for the radiator. Any suggestions on that? Also will need an ele fuel pump which he wants to put in the trunk. He says they run $2-300 and the difference is the noise? Thanks in advance, Lanny Quote

DJ194950 Posted January 10, 2015 Report Posted January 10, 2015 (edited) Why not to build a hemi powered 50,s 4dr. or mopar wagon with a mid engine?? DJ Edited January 10, 2015 by DJ194950 1 Quote

Dave72dt Posted January 10, 2015 Report Posted January 10, 2015 (edited) Swinging pedals means they will hang down from under the dash, similar to the truck the drivetrain came from, not through the floor boards. An electric fan can be had from aftermarket sources, (Summit, Jegs, etc.)or from a salvage yard, RAM dealer. The HEMI may or may not have a provision for a conventional fan. Fuel pump will likely be mounted in the tank. It's a high pressure system feeding fuel to the injectors, not the 3-4 pounds that feed a carb. It's quietest in the tank. All you'll hear is that initial short buzz when you turn the key. The car does not have to be lowered or chopped to fit the drivetrain. Not lowering it may help with placement since there would be less concern with ground clearance. Take some pics of the wagon's engine bay and trans tunnel with and without the Hemi in it if possible. It may help your builder with what needs to be done to make everything fit and save some trial and error time. Edited January 10, 2015 by Dave72dt Quote
Plymouthy Adams Posted January 11, 2015 Report Posted January 11, 2015 Talked a bit with Lanny..it seems that the tranny may be an automatic and not a manual...thus the swinging pedal will not be an issue here.. Quote
fstfish66 Posted January 11, 2015 Report Posted January 11, 2015 why do you think you can not use the fat man steering conversion ?? following this swap,sounds interesting,,, Quote
