I have a 5.9 cummins in my supercab , I bought an adapter plate to mount the cummins to a ZF 5spd trans. I already had a ZF for a 460 so that is the plate I purchased. I used the 1994 up Dodge truck engine mount, because their design looked superior for vibration absorbtion that he earlier ones.
I made my own frame perches. had to trim down the front crossmember and then box it in again. plan on putting in a forward crossmember similar to the old higboy ones right behind the bumper.
ZF needed some trimming to clear the 205s shift rods but the lever pivot point worked fine . I made up an adapter for Tcase mount from a frame rail side(heavy truck stuff). fun drilling it.
ZF needed some grinding for clearance issues, against firewall lip.
I used the slave and master clutch cylinders off a 1991 diesel F350. (availability)
modified the lever from the 91 Ford to fit the 79s clutch cross shaft under dash, and mounted the master to the existing firewall.
I wanted fast warm ups so I mounted engine pretty far forward not worrying about space for the mechanical fan. I used a 1991 Ford Van rad. for a V8 gas and mounted it on the front flange of the rad support, this brought the top tank and rad cap VERY close to the back surface of the rad support.
Things I would do different next time:
put in a body lift
mount the engine further back(oil pan clearance for the front diff)
use the mechanical fan
give more room for the starter when fabricating frame perches.
I have driven it enough to work out all the bugs .
:mad: I broke the starter nose when shutting down one day, in my fabricating wisdom(d'oh) I didn't leave enough clearance for the starter to framerail. now I am in the process of redrilling the holes in frame perches.
Up 1/2" and to the drivers side 3/4" never realized how the rubber mounts would "settle" after they had been in for a while.
If you are not a fabricator at heart do not attempt this conversion. there are a lot of conversion kits and ideas out there and I wasn't happy with the quality/durability of most of them so I did it myself.......... it is a big job, but if you have the time its worth the efforts :cool:
Truck is a snow bank right now but I will take some pics by spring, as I hope to have it on the road again by then. :rolleyes:
