Yes you can. I have a 6v92ta w/ 730 auto trans in my 4104. Bought it that way. Know a guy in Montana that can do it for you. |

this is something i'll have to do myself.
i hear you need to change the rear axle also.
does this mean pumpkin and axles ,or whole housing . does all of this usually come on a cradle that fits right in or does it need retrofitting on my old cradle
thanks for the input.

Dounan - Here is a repost on the same topic:
Probably the most common powertrain swap for the 4104 is the 6V92TA / V730 combo, which can frequently be found in a donor transit.
The 6V can be tweaked to 350 hp easily w/ an injector and turbo change, no teardown necessary. Gives over 100 more HP than the workhorse 6-71.
Note that you MUST change the rear axle also, as the offset of the ring & pinion are different on the 4104 vs other model angle-drive coaches. (On the 4104, the bevel gearset is after the transmission. Starting with the 4106, GM put the bevel gears ahead of the gearbox, as the bevels were not holding up during development testing to the greater torque of the V-8 when multiplied thru the lower gears of the transmission. This change also required offsetting the ring & pinion pumpkin to match the new layout.) If you don't make the axle change, be prepared for driveline vibrations and short U-joint life.
You'll also have to upgrade the radiator to handle the additional cooling required by the higher HP engine and transmission. An interesting challenge, as the body cutout for the radiator is quite a bit smaller on the 4104 compared to later, V8-powered coaches.
This is one of those things where you have to ponder whether the expense of doing a powertrain swap is really cost-effective in relation to the shell's value. . .
Of course, the answer is no, but that would also be true nowdays with a $11K MC-9 being swapped from manual to automatic.

RJ
thank you for the info.
i don't mind th engine work ,but i just dont want to get into pulling and changing the rearend.
i guess i'll just have to keep looking for a reasonable 6-71
