Anyone ever mount a v6 on an inline mid???

One thing about spending several days in a tractor, It gives you lots of think time. Well, maybe I'm getting carried away but I am curious if it would work because I need a short shaft v6 for my tigershark and I'm not needing super high horsepower.

It requires someone with good welding experience. A freind had a v6 adapter welded to a 15" in-line mid. Put it on a 17" Allison with an xs lower unit. ran like a scalded dawg, but cost him.

I don't see how it's possible with any reasonable exhaust efficiency. The exhaust holes on the 72 and newer shortshaft inline mid are on the left side (all inlines actually, but more defined on the later stuff and closer to impossible to move with the stacked plates) and the V6 holes are on the rear. It would be all but impossible to get an adapter made that would flow properly because the ports are about 3" off and 90º rotated. The total width of the V6 ports is also much wider than the inline mid section is at the top internally. The other problem is that only the front four bolt holes will line up. (two on each side)

SuperD, I think yo' buddy must've had some other combo.

Well I guess you never know unless you ask. Thank you.

He had a v6 20" cut below the adapter plate and had it welded to a 15" in-line mid that was cut below th adapter. Some guy in Chicago did the welding. That was probably 25 years ago. I'll try to see if he still has it and get some pics. He started with a 150xs on a 15' Allison. I'm talking something like a 1974 model v bottom or so. When the v6 came out he didn't want to drill more holes in his transom. This was before everybody was running jackplates. The guy did a beautiful job of welding it and reinforcing the mid. Looked factory. This guy was in his mid to late 40's then. Maybe long gone, but I'll try to locate his son. We went to school together.

what about gear case life?

Isn't the XR4 gearcase more or less the inline 6 gearcase?

From experience it is shaky with 150HP and if you go less than that you may as well stay inline.

Raceman, it's a bolt on. :rolleyes: If you use a T2X 6cly exhust housing.:D Just go buy a Champ housing and sell your xs stuff.

I have a guy that mounted a v/6 to a 15" inline mid I will get the number for you today! He would be glad to talk to you.

DaveS, the question was inline mid. A T2X is a V6 mid with an inline 6 adapter.;)

I don't know who these guys are, putting V6 powerheads on inline mids supposedly, but since the powerhead bolt pattern at the rear is damn near double the width of an inline, and the exhaust would have to be moved approx 6 or 8 inches within the thickness of whatever the adapter plate is, I ain't believin' it can be done efficiently. If somebody DID in fact go to the trouble to graft the to of a V6 mid WAY DOWN below the adapter plates to the bottom half of a inline mid, it'd still be an abortion exhaust wise, unless they did it far enought down that the tuner would have width. A V6 tuner ain't even close to slidin' down in any part of a naked inline mid. But......... I don't see how you'd even still call that welded up concockshon an inline mid anymore. As far as just putting one on the top of an inline mid, I'm declaring BS on somebody having done it unless they ran the exhaust out the back of the block.
