I went from a slant six/833od to a 440/727. same length. Put the 8 3/4 rear under it, and had to shorten driveshaft about 3/4" for it to be right. I run a driveshaft shop, so that wasn't an issue!

84 D150 440/727
79 /6 swb D150
1964 A100 window van. Just because it has spark plug tubes doesn't mean it's a Hemi.
