1940 Plymouth (P10) getting heart transplant..heart: 79 Camaro 250 Cu 3 spd manual Sign In

I need some good advice. I put a inline six from a 79 Camaro in my P10. I have various questions, however foremost at this point is what pollution parts of the engine don't I need? Also, how many splines coming out tranny, it's a 3 spd man? If there is any other advice I am open to suggestions. Thank you, Somberlights

This could be a total novel of questions for you.


Forget about what emission controls the '79 has. I think just an EGR and PCV and neither bother anything so leave them intact and working.


Any such thing you should have the driveshaft from the Camaro to use. I just don't know what type of set up the '40 was. If that was a "Tunnel Drive" such that it hid the driveshaft you need some help beyond me to probably make up a driveshaft to the rear end if possible from that Camaro as well.


Assorted things that will be a problem or hassle is the speedometer being able to work at all and harder to make it accurate. I bet the fuel pump (if any) on the '40 was also a vacuum pump on top to run vacuum items possibly wipers but could just use manifold vacuum from the Camaro and expect wipers to quit working while accelerating or going up hill OR find an electric vacuum pump that will work.


Tons to consider, fabricate from design YOU come up with as IMO that's an odd choice of engine for playful use to just toss into something,

Thank you very much for answering some of my questions. The reason that I went with the engine that I did was that the price was right, I heard it running, and it sounded healthy. I was told that it was possible to marry this engine and car, but difficult. I do like a challenge. So far, things are going well. I also wanted to keep an engine that was close to the original in horsepower. The reason being that I'm keeping the drum brakes. They are all new, the owner before me put 4 new tires on and had all the brakes done. I have added a brake booster from an 82 Camaro. So we will see how this works out. The driveshaft from the Camaro did not come with. I have the original driveshaft from the Plymouth, not a hidden one. (not sure what that means, but from the description you gave, does not apply here)
I'm converting it over from 6 volt to 12, keeping the original gauges. I purchased a book called "The Official 12-Volt Conversion Guide" which is helping me a great deal. However, my wife's dog ate the book. Currently pulling pieces out!! Having to send off for a new one.
If you have any suggestions or questions for me, it would be appreciated. I can use all the help I can get!
ps... my wife is calling this the Frankenstein Car.
Thank you. Somberlights aka Eric g
retired too.

Smile - The first problem is you like the price of the Camaro engine! It will take you more $$ or thought to just some linkage to work properly than a whole restored '79 Camaro would cost so if on a budget stop now with this hobby!


Tunnel drive is (perhaps slang known to me) when engine, trans, driveshaft tube and rear differential are all bolted up as one unit making like a "T" out of the entire drivetrain and would need unreal machine work vs just cutting up two drive shafts to make one that does the job for this.


This type of creating stuff never was my thing just a very curious observer of those that made whatever they wanted out of a shell of a car or something with whatever powerplant they wanted most usually a Chev small block as there's a lot of support and endless ready to go parts to make those fit and adapt.
While you wait for your 6V to 12V conversion book I think you'd do well to subscribe to Hemmings Motor News which is/was old car/vehicle hobby anything for resources like a phone book of ads for everything you can think of.


You also need to know a lot of local help for assorted machine work and metal fabrication.


Join some HOT ROD type club now. You'll need some contacts for silly stuff like I said just getting the speedometer accurate will wipe out a month no doubt and cost a fortune in time and money to get right or totally do without and make it a LED screen dashboard or something.


Are you up to even any of this? Just mentioning that you are in need of help with 6V to 12V I think you are way over your head for anything like this never mind you are really engineering things bit by bit so need to draw out diagrams of what you need if you don't already have a shop to basically turn raw metal into what you want.


Best part of a hobby of the sort will probably be meeting a lot of people doing some odd project like this and liken what you'll run into dragster riding lawn mower and things like that.


You could have plain fixed up the original '40 engine 100 times over for what lies in front of you now.


Back to top on this. If you want this to turn out to just drive nicely for you without hassles and don't even care that much about final details at all you'll still need the space and some serous bucks. If you want a real eye catcher unique something when done and have to ask how much anything costs this isn't for you at all.


To even get started do get a real paper copy or online subscription of this Hemmings Motor News thing. Sounds like a newspaper but not. It's a world of exact vehicles to all the trades that support the old car anything. Link to it not generally allowed here is....

Have fun with a hobby of the sort. If it's causing financial problems for you it isn't for you,

Is this your dash and interior? Those type pedals on floor?



OK - Changed my mind for suggestions for you but start with a question:


WHAT IS WRONG WITH THE EXISTING ENGINE AND TRANSMISSION?


Do you have any idea how much easier it would be to fix those than totally redesign this drivetrain? Just to make the pedals work on the Chevy drivetrain would be a total feat of design and work that alone will be more effort than a total redo of existing OE if OE stuff.


You aren't looking to make a Hot Rod with a 79 lame as can be Chevy straight 6 - trust me. You didn't want higher power and I think if this car is worth anything you are just ruining it's value for a ton of work. Who the heck wants a Chevy 6 in a Plymouth of that vintage?


Sorry for the discouragement but I can't find much interest in either vehicle never mind butchering the Plymouth and think you'll just end up with parts to sell and an engine nobody wants either as they were not of special interest but for those who couldn't afford the V8 in a Camaro and not a special year for those either IMO,

Re: 1940 Plymouth (P10) getting heart transplant..heart: 79 Camaro 250 Cu 3 spd manual Sign In

This is the wife. We started out with the plan of restoring the 40. Everything under the hood looked in awesome shape, and I managed to track down the original owner, found all the maintenance records, etc. The car has been sitting since around 1964. Figured the guy (in early 30's at that time -I even found birth/death certificates) had decided to upgrade to either something more family friendly or something speedier. What we didn't know was that the car had been overheated... to the point that the pistons had fused to the block. Just completely toasted. So... we either do a heart transplant or we look at our pretty paper weight. As to whether or not we can fab things up... my husband has already been fabbing things to just get the engine into the car, so I'm not worried about this. He was in construction for 40+ yrs. He IS of the type to create whatever he wants out of materials available. That's one reason we bought the car. To keep him from being overly bored. We are asking for advice on how to get this done right, not a lecture on what we should have done or dire warnings about what might be ahead. We are well within budget.


ps... his trike can be seen at ericgpeters.com/PoppysToy.html


Thanks. Cherry

Your pic of the trike will never show for me. Not the point. Seems you know what the motivation is with this thing. If this just sat since 1964 it would have been tons of work just to be ready to try to run it. Those engine even seized you probably could completely re machine and make right easier than this "heart transplant" as you both put it from one animal to another is to keep someone busy it will.


If he already fabricates parts to make things fit and work there isn't much help I can be from here. You/he may want to subscribe to the Camaro for at www.AllDataDiy.com for specs for that engine and trans or get paper service manuals if preferred on line for sale probably dirt cheap for just drivetrain for a 6 one or whole set for everything about the Camaro.


Goal achieved - It will keep him busyCool
