Im doing a straight axle swap in my 99 durango. Now I have accuired a 413 truck motor out of a 76 motorhome. I was wondering if the bellhousing bolt pattern is the same as the 360 in the Durango?

 

Been a long time since I seen a 413, The 413 is a big block, itwon't bolt up to your 360 bellhousing (which is a small block) as far as I know.

 

Not to mention the computer.

Big and Small Block so they won't work.

 

The computer is coming out. Severe wiring problems. The dealer told me that the intire harness has to be replaced at a cost of 1200 dollars. Minimum the intake will be changed to a four barrel, found the intake already. Never thought about the big block small block. Dumb over-sight. Thanks for input
