Will this engine fit a NP 435 transmission in a 1985 dodge 250?
Per ATK "THIS ENGINE IS A STOCK DODGE 360 MAGNUM BLOCK & I DO NOT KNOW WHAT TYPE OF TRANS THAT IS. IF THE TRANSMISSION WAS MOUNTED TO A 360 DODGE ENGINE ORIGINALLY IT COULD WORK."

Exploring replacement in my 91AeroCruiser, stock is Chrysler 360 w/3speed auto. Is there a transmission recommended for your higher hp 360? The chassis is 1 ton Dodge truck w/ single wheels in rear
This has the standard small block mpar bell housing pattern so a Chrysler transmission (like a TF727) will work well.
