m16ty Posted November 15, 2015 Share Posted November 15, 2015 I've seen a 8v71 in a B model. It does fit but it's awfully tight. Quote Link to comment https://www.bigmacktrucks.com/topic/42675-mack-b61t-tranny-fitment/#findComment-311544 Share on other sites More sharing options...
j hancock Posted November 15, 2015 Share Posted November 15, 2015 The Mack B-615 was equipped with the NA 864 V8. An 866 with the turbo and associated plumbing will need lots of fabrication and lots of $$$. 2 Quote JimIt doesn't cost anything to pay attention.

theakerstwo Posted November 15, 2015 Share Posted November 15, 2015 Also when a END864 engine was installed at factory into a B615 it had a special oil pan to clear front axle.I would think that would be hard to find.The intake was different than what was on other trucks. 2 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/42675-mack-b61t-tranny-fitment/#findComment-311571 Share on other sites More sharing options...
Brian Blaylock Posted November 15, 2015 Share Posted November 15, 2015 The B-615 also had the big radiator wider hood narrow headlight panels different panels on top of fender front and rear engine mounts in different place and the cab set higher off of the frame just to name a few things that are different between the two 2 Quote Link to comment https://www.bigmacktrucks.com/topic/42675-mack-b61t-tranny-fitment/#findComment-311574 Share on other sites More sharing options...
