SM 465

Got an adapter plate? I don't think an AMC bellhousing was made for the SM465 (but, I could be wrong...)

Side interest - I've got a few 4.0 bellhousings out in the garage - I should be able to work up a bolt pattern for our end of things one of these days...

i dont know much about bolting up a sm465 to a 4.0L but i do have a sm465 mated with a chevy 350 and np205 and its great for a slow crawl. i like it better than an automatic for crawls thanks to its 6.55:1 low gear. What kind of transfer case where you planning on bolting up to the SM465 ?
 
i have two options fliped dana 300 or a 4 to 1 231. i dont think the 231 would take the extra torque, i was also think on doing a 231/dana 300 doubler.

doyou ( jeep 87 cherokee) have the 465 in your xj
 
well i'm putting in an np435 but the dimensions are close. i had to cut the tunnel up pritty good to get everything to fit. Those old 4speeds are tall. I didn't want everthing hanging way below the frame rails so I pushed it up there a ways.

I had to pull out the heater core as the tranny shifter came out right below it.

not sure i fallow. the three levers are the shift levers. behind that you can see the rear output for the 205. I had to cut the hole large enough for the parking brake rotor.
 
Nice. I just re-read and caught the doubling going on there. What's your crawl - about 200:1?

"Lightning Rods" are an old racer's shifter, usually used with Lenco four-speeds and five-speeds. Essentially (and in order going away from the driver,) you have several shift levers:

Reverse-Neutral-First
Neutral-Second
Neutral-Third
Neutral-Fourth
Neutral-Fifth

Upshifting was a matter of grabbing the next lever out and pulling it toward the rear, downshifting was grabbing the last lever you pulled and pushing it forward. Reverse, on the first lever, was pushing it forward - first was pulling it back.

Essentially, it removed the need to follow a pattern when shifting - you just grabbed the next lever. I think it's been adapted to other boxes - the old Muncie Toploader four-speed comes to mind - and you could tell how many forward speeds you had just by counting levers.

If you want to know more, I think Hurst has been doing a version of Lightning Rods for some time - you can probably start there. Or, Google <Lenco> and see what you find out. I haven't seen one in years...

Ah now I get it. I never knew that’s what they called that multiple shift lever racing setup.

When you said "Lightning Rods", I though you were making a wise crack about their height in relation to the surrounding areas. IE. a lightning rod being the tallest point on a house.

They are actually brake and clutch levers from an old XJ. I converted to the manual and got the wrong bracket/peddles the first time out so I decided to put them to use.

I guess in retrospect they do work similar to what you describe. The far lever allows me to shift the 203. and the closer (to the driver) are the front and rear outputs on the 205. All levers forward = fast, all levers back = slow.

Crawl ratio is only about 140:1, being only 4:1 in the cases, 6.7 or so in the tranny and 5.13 in the diffs.

Mine's not too much better. :flipoff:

although that's NV4500 -> NP231 -> D300.
