BobT-47P15 Posted July 16, 2015 Report Share Posted July 16, 2015 I believe it has been done several times by assorted guys out there in hot rod land. I don't know any of them personally. An inquiry on the Jalopy Journal "HAMB" forum might come closer to a reply about that.....as many of their members favor putting a Chevy V8 in anything and everything. Of course, here on this forum, it is usually suggested that a Mopar engine would be a better choice, keeping it all in the family. There are some good Chrysler product engines and transmissions around. Quote Link to comment Share on other sites More sharing options...
jeffsunzeri Posted July 16, 2015 Report Share Posted July 16, 2015 I have hauled many Chevy engines and transmissions to the scrap yard in the trunk of a '47 Plymouth and in the back of a '42 and '47 Dodge truck. I used plastic sheeting to protect the bed and trunk compartments from soiling. 7 Quote Link to comment Share on other sites More sharing options...

Plymouthy Adams Posted July 16, 2015 Report Share Posted July 16, 2015 (edited) I think the main reason you see this type install is that many do not have the skills, shop, cutting tools and welding experience to fabricate motor mounts and go with what is normally found on rod sites in a one size fit all department.

Tom Hartman Posted July 16, 2015 Author Report Share Posted July 16, 2015 Haven't seen any of the above example mentioned above ...just trying to gather information and I'm not a pro fabricated just would like to get this thing on the road Quote Link to comment Share on other sites More sharing options...
55 Fargo Posted July 16, 2015 Report Share Posted July 16, 2015 Haven't seen any of the above example mentioned above ...just trying to gather information and I'm not a pro fabricated just would like to get this thing on the road Not a problem, maybe try the search feature to see what threads are listed for a V8 swap. AS mentioned by Bob T, try the HAMB forum, do a search, message or ask Guys like Hotrodprimer, Pork and Beaner, and a number of others. SBC, why not, your car, your money, your decision. I would like to see a Ford 300 6 installed in a P 15, but no doubt it is pretty long for a n uncut fit.....good luck Quote Link to comment Share on other sites More sharing options...

Solution OldDad67 Posted July 17, 2015 Solution Report Share Posted July 17, 2015 Anyone have any knowledge of putting a chevy engine and tranny in a 47plymouth? Hi Tom not everyone on this site likes Chevy's, as a former Chevy rep I can tell you from experience. I'm putting a 327 Chev in my P-15 with a Muncie 4 speed and a 56 Chevy rear end and a 57 Chev gas tank. I figure it's my car and I'll enjoy it my way. I don't build cars for other people's likes only my own. I'm using an Aluminum radiator with electric fan. Clutch linkage is a challange and an automatic would be an much less work but not as much fun. I have a friend who is putting a 55 Dodge Hemi in his 47 business coupe with a GM 200 r4 tranny behind it with Ford rear axle. I had to cut the rear transmission mount out and fabricate a new cross mount for the tranny. Not a big deal and you will probably have to do this for most V8 swaps. Let me know what information your looking for since I don't know your skill set, but make your car the way you want it. E-mail me anytime with questions, I may not be the smartest guy around but I'll do my best to help you with your project that's what this site is all about. You can ask me about my 30 Model A with my "Packard" motor too. 1 Quote Link to comment Share on other sites More sharing options...

dale Posted July 19, 2015 Report Share Posted July 19, 2015 You will have to put in a new trns. crossmember. I put a chevy 265 into a 47 plymouth once and used a 4 inch channel for this and it went easy. If you use an automatic trns the plymouth speedometer cable will work also but registers higher than it should. I used to scare the pants off passengers .. Im putting a chevy 350 with a 350 turbo in a 1946 convert now. If you do this move the motor 1 1/2 inches toward the passenger side to clear the steering box using factory exhaust manifold. Leave the trns. on center.. Speedway Auto has front motor mount bracket and rubber mounts kit along with everything else like trns. flexible dip stick etc.. Im using a repro aluminum radiator along with electric fan and radiator trns. cooler. Using a B&M floor shifter that has a cable so it can be placed about anywhere. With the stock 350-350 Im using the Plymouth rear end but there will not be a parking brake Replaced the seats with tan leather 48 inch wide ones I got that are like new from mid 1990s Chevy Suburbans. People never hardly use them and they are mostly like new. Got them from two different sellers for $30 apice. Good luck.. Quote Link to comment Share on other sites More sharing options...
dale Posted July 19, 2015 Report Share Posted July 19, 2015 Clutch linkage shouldnt be a problem if you add a hydraulic one. Kits are available an dont cost much. Only have to push clutch in about an inch. Quote Link to comment Share on other sites More sharing options...
Tom Hartman Posted July 20, 2015 Author Report Share Posted July 20, 2015 What are you using for drive shaft pinion yoke ? Thought about that too but haven't found yoke .understand there is an interchange Quote Link to comment Share on other sites More sharing options...
Tom Hartman Posted July 20, 2015 Author Report Share Posted July 20, 2015 Know where suburban third seat is..measures 48 across top only need one mine is business coupe..your convwritable sounds really cool and rare .the spell check thinks it's smarter than me.might be right Quote Link to comment Share on other sites More sharing options...
Dave72dt Posted July 20, 2015 Report Share Posted July 20, 2015 If you move the engine mounts to the right, the trans mount point also has to go to the right. The crankshaft and pinion shaft are supposed to run parallel, both vertically and horizontally to keep the U joints in phase. Quote Link to comment Share on other sites More sharing options...
dale Posted September 25, 2015 Report Share Posted September 25, 2015 Those Suburban seats are everywhere. I found mine off Craigslist. Quote Link to comment Share on other sites More sharing options...
dale Posted September 25, 2015 Report Share Posted September 25, 2015 Dont think the transmission has to run parallel. I had a 55 Desoto with a hemi and the factory installation had the motor in crooked to center by about two inches. Universals are made to run crooked.

I had a 55 Desoto with a hemi and the factory installation had the motor in crooked to center by about two inches. Universals are made to run crooked. IT MUST RUN PARALLEL it is however not critical they be inline...offset up/down, left/right or combination of both is not only good but an important part of the actual install to promote smooth operation of the u-joints.. 1 Quote Link to comment Share on other sites More sharing options...
Ulu Posted September 28, 2015 Report Share Posted September 28, 2015 (edited) Yes, they must be as Parallel in both dimensions as you can get them. If the shafts aren't parallel, your driveline will vibrate, and thump under hard loads. Your u-joints and oil seals will wear out fast too. I've seen people lose driveshafts on the freeway, and it's pretty dramatic when a u-joint gives out suddenly, so it pays to keep an eye on these.
