teched Posted October 13, 2020 Share Posted October 13, 2020 Please don't shoot me but I may have found a solution to the junk 401. I just bought a 6v53 and a 4-53 (package deal). The old mack has a TRD77 10 speed. I would like to mate this to the 6v53. I think the TRD77 has SAE 3 bell. Can I bolt the two together? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/64567-1958-b42-left-in-the-woods-gets-some-engine-options/ Share on other sites More sharing options...
tjc transport Posted October 13, 2020 Share Posted October 13, 2020 6V53 is kinda big. i think you would be better off with the 4-53. that will be plenty of engine, especially with a 10 speed.

doubleclutchinweasel Posted October 13, 2020 Share Posted October 13, 2020 That's kinda interesting! Might need taller rear gears? Depends on how fast you wanna go.

General Ike Posted October 13, 2020 Share Posted October 13, 2020 Got a 6v53T in my B85F.

tjc transport Posted October 13, 2020 Share Posted October 13, 2020 didn't say it would not fit ED, just saying it is a pretty big engine. the 6V53 is around 1500 lbs the 4-53 is only around 1100 lbs.

teched Posted October 13, 2020 Author Share Posted October 13, 2020 The 4-54 has a bad turbo and ran away. There is just a touch of oil on the stick. I bared the engine over by hand and it feels ok. My original plan was the 4-53 but once I found out it ran away I wondering if I'd be better off with the 6v53. I think Harbison has a 6v53 in one of his B's. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/64567-1958-b42-left-in-the-woods-gets-some-engine-options/#findComment-462354 Share on other sites More sharing options...
Maddog13407 Posted October 14, 2020 Share Posted October 14, 2020 6v53 in a B85 would have a bigger bell. probably a 2 with a 67 series trans. i have a 401 or two i would let go for cheap. probably need a ring job as they smoke but can hear run 1 Quote Link to comment https://www.bigmacktrucks.com/topic/64567-1958-b42-left-in-the-woods-gets-some-engine-options/#findComment-462371 Share on other sites More sharing options...
