76 Duster

It'll bolt up to a 318 but it won't even come close to fitting in the small transmission tunnel of an A-body. Do a search on here for 518 install and you'll find many threads on the subject that shows what it takes to install one. I can tell you it's not for the faint of heart.

BTW: your incorrect about the dipstick. An A518 is basically a 727 torqueflite with overdrive. All mopar dipsticks are on the passenger side.
