Veteran Posts: 157 Location: bountiful, Utah | I just got a 1972 413 and torqueflight with the emergency brake on the back of the transmission from the same year motorhome. Does any one know if it will work in one of our forward looks? It also has the push button cable, and I'm hoping that the entire engine and trans would work in one of my cars. Does anyone know if the 413's shifter cable will connect to the existing push buttons? Does anyone know if the motor home trans has a park position? Could it be hooked up as well? Does the later 413 use the same block as the earlier 413? In other words, will the earlier motor mounts bolt up to this block? Is the transmission mount in the same position? I'd love to put this in a 57 Plymouth that I have and am anxious for someone who knows to chime in on this site. Does anyone have any information to see how viable this possibility is? Around here there are all sorts of old Dodge motor homes available cheaply with low mileage big block motors. This might be a slick way to update the drive line in our beloved Forward Look cars, and make more Forward Looks road worthy. Thanks, Scott | ||||||||||||||||||||||||

There are kits to change over to the spool style mounts if you have to start from scratch. Cable end may be different. Don't know. Look up imperial Services in google and see the pictures of the cable they make. Should be a very easy swap. Marc. | ||||||||||||||||||||||||

The Park issue when swapping the later TF into a FL has been discussed at length, an auxiliary mechanism is need to activate Park when using the FL pushbutton shifter....best to just use the MH parking brake since it's there. | ||||||||||||||||||||||||

Expert Posts: 1223 Location: Ramona, CA | Does it have a shift cable going into the transmission like a pushbutton or is it going to linkage? Most of the 1970s motorhome ones use a remote shifter that has a lever with a ball handle. Having the brake on the tail makes it easier to use in the old ones. | ||||||||||||||||||||||||

Here are some specs I found regarding 413 motorhome engines. Very low compression/HP, but torque does not appear that bad. http://www.flxible.net/enginespecs.html

Elite Veteran Posts: 888 Location: Peoples Republic of Oregon | ...hhhmmmm.... some MH engines used the 'truck' heads and some used the 'normal' pass style heads. The truck heads are quite different in design although, as a package, in a MH, they did their job very well. IIRC, the difference is in whether the MH was a Class A, B or C. As to the 'low' hp/tq numbers, recall that for 1972 all manufacturers switched to net ratings from the previous gross ratings in an effort to keep the insurance industry happy. In the passenger car engines, the only real change was a drop in c/r. | ||||||||||||||||||||||||

Elite Veteran Posts: 1102 Location: Hayward, Calif | You will have to get a pass car oil pan and pick up tube. I put a 360 and T/F from a 76 MH in a 59 Dodge. I used the MH eng mounts, had to modify them a bit to fit the front Xmember and used that flat rectangular rubber mount. It holds the eng down pretty tight. Makes a nice clean mount. I made a flat plate and bolted it to the trans Xmember, and drilled couple more holes for the trans mount. You can raise or lower at this point to get drive line angle and get a dr shaft made. Since the dist is in the front on the 413, you shouldn't have clearance issues with the heater housing. Left side exh header pipe may have clearance issues if you have power steering. Allow enough room so you can still get the starter out without having to remove the manifold and header pipe. I found the MH radiator physically too big to be used. Good Luck, Jerry | ||||||||||||||||||||||||

Expert Posts: 1497 Location: Fairfax, Minnesota | "The usual recommendation is to replace the truck heads used in motorhomes with car heads." Will passenger car heads be enough to bring the CR up to original 10:1 or are the pistons dished also? | ||||||||||||||||||||||||

Veteran Posts: 157 Location: bountiful, Utah | Thanks for all the great information. I'm out of town this week, but next week will do more specific research. All that was left of the motor home was the complete chassis. It was to be turned into a parade float, so all I got was the complete engine and trans. The radiator was huge as was mentioned earlier. How do I know if I have truck or car heads? | ||||||||||||||||||||||||

Elite Veteran Posts: 1102 Location: Hayward, Calif | There is a raised cast number on top of the head. May have to take the rocker shaft off to see it. One of the guys here can ID those heads or call Summit and ask for tech support. More than likely the pistons will be dished. Even if you use the MH 413 as is, it will be way more than enough eng for that Ply. Depends on your budget. You can easily spend a $1000 overhauling and eng, and that's if you do it yourself.

The exhaust manifold design is the fastest visual check.....someday I'll figure out how to post photos on this forum.... If you go to ebay and search for '413 truck exhaust manifold' you will see both styles. Which bolt pattern looks like yours? | ||||||||||||||||||||||||

Veteran Posts: 157 Location: bountiful, Utah | It definitely has the truck exhaust manifolds on it. I'll have to install a set of car heads. Thanks again for everyone's knowledge. This is the best website. Everyone is so willing to share valuable information. | ||||||||||||||||||||||||
