Dauntless in late model CJ5

Has anyone ever put a Dauntless V6 in a later model CJ5?? I have an '80 CJ5 with an Iron Duke and have access to a 71 Dauntless complete setup (3sp and TC included).
I like the idea, but am curious of the gotchas.....
Also I would like to keep my D300 TC case, is this possible????

To keep the D300 you'd have to find a transmission that bolts to the 225 and then has an adapter to the D300 available. One that comes to mind is the SM465 which you can find bellhousings that will work between it and the 225. Then you'd need an adapter to attach the D300.

I'm a big fan of the 225 odd fire myself, but just something to think about... you may want to check into the legality of swapping an older engine into a newer jeep. Not sure if it would apply to a jeep that already qualifies as a classic, but just a thought. HTH

Different eras. You'd have to change motor mounts, rear axle is going to be centered, driveshafts, etc.

Better choice would be an EFI 350 or 4.3 swap.

Anything is possible. You have plenty of engine compartment space especially with the long front fenders. Bolting the 300 to the tranny will likely be a hassle. As CSP mentioned, you'd probably end up running an SM420 or 465. They'll both bolt right to the 225. Then get an adapter to mount the 300 to the tranny. Or, just run a Dana 20 to line up with your rearend. You'd have to completely fabricate engine mounts and an exhaust system and come up with some plumbing for cooling/fuel, etc. The 225 makes lots of torque, but it really isn't a huge powerhouse. I ditched mine for a SBC. By the time it's all said and done, a SBC swap would probably be faster/easier and be a lot cooler for less work.
