One of the Mopar magazines did a favorable article on these Guys.

I would definitely go 904-based transmission given the first gear ratio options and less parasitic drag.

I learned one thing quickly after owning my first 4 speed 318: the 727 is a power-sucking turd. I've had 318's and 360's with 727-based transmissions (3 speed and 4 speed od's) and they subtract a noticeable amount of horsepower. twocents


I had one of those SMR adapters I bought off of Craigslist that I was going to use to mate a 400 to a 518. It involves lopping of a section of the block where to the starter bolts. No going back. Went with an ultrabell instead and it's been great. Figured finding another 518 was easier than building another motor if it went south.
