Project: Waste a good tahoe

[blacksheep10]

Okay, so after the input shaft on the 4l60E broke, he decided it needed a 400. My acquaintance that used to run mud runs had a 400/203 sitting around from his pit truck, 400 is mildly built with better clutches/bands, etc and a shift kit. $300 for the whole thing with 10 runs on it. we took the shaft out of one of the 400's I had out back that was off an 85-91 1 ton with the circle 6 205 and put it in his, and put a 84 and down 400/205 shaft back in mine out of another broken tranny. then we put the broken cased tranny back together to keep all the parts in the right spots. Next was an adapter off a 400/208 off ebay, and putting a 32 spline input in his passenger drop 241 out of my drivers drop 241. also a sye. the crossmember was different, so I had to make a new one of those. I also have to cut the extreme angle front shaft apart and make a smaller tubed 1350 one (its a 2 3/4" tube 1310 now, he bought a yoke and long slip that are on the way) the second round is about done, we are waiting on driveshaft parts.

some random shots of the shaft and 25 minute crossmember.

Steep but once the wieght is on it, it wont be unbearable. you think this will be better than a CV? I know its way cheaper, but the 1310 is going to be swinging in a serious speedup, slowdown, speedup, slowdown arch.

I get confused easily and all the 350, 400, 205, 241 talk made me need a beer.

Nice work Mr. Technology.

that shaft is hanging WAY below the pinion on the 60. the 60 is at full droop on the strap and the shaft is inches below it not hooked up. the shaft is currently a 1310 slip and he bought a 1350 yoke for the 60 that we put on. when the long 1350 slip gets here I'll make a shaft with 2.25" tube and a 7" travel spline and cut the larger tube off the 1480 yoke at the top for the smaller tube. I am still impressed with the angle those 60 driveshaft yokes have.
yes a cv is better, but not stronger than a 1480. you know how I know? because there are 1480's in the axle just downstream under 4.56x the torque and at the same angle when the wheel is turned

 

[P]

Frame rails = wasted.... ask me how I know laughing


Is he gonna wheel wheel this thing or just party cruise it ? Its coming along man ! how about an overall shot of the big rig

 

[blacksheep10]

just drive it. might play in the mud a few times, that's it. mall crawler all the way........with built tons and high steer laughing.
I'll get some pics when the shafts come in so we can pull it out.

 

[blacksheep10]

Done. He's driving it home again today. took it out last night and tried it out. the long slip front is a great deal for $150, 9.5" of spline, 1350 forged yoke that's extra deep and allows the flex of a 1410, and is tight and sealed. The rear cv 1350 40* is sexy too for the money. I got the smaller tube front done and the 1480 cut apart and put back together with the 1 ton stuff. With that angle there are some good vibes out of that front, but it's tolerable....moreso than a $350 cv laughing this one cost him $50 with my labor
Its not my thing, but he was smiles from ear to ear. the reason the wheels are different is because the new boggers are on front with my old black 14" wide barts, and my worn out boggers are on the back on the faded AL 12" wheels. the other 2 new boggers and black wheels are in the back of the tahoe because they each ahve a cut in them.

Nice work. Tall bitch for sire. Seems like a waste of one tons though doesn't it? Is it open/open as well?

 

[blacksheep10]

locked rear, gonna get a detroit front if it doesn't perform as expected.

damn, now I wish I would have kept my stock 60 stuff instead of selling them...LOL how long is the front shaft?

meaning the stubs for the front driveshaft joint?

how long is the front shaft?

Brian

34" iirc

 

[blacksheep10]

its now in olathe. here are some pics of right before it left
notice the smaller od of the front shaft. (was almost 3" od)

as it turns out, you have to take .033" off the lip seal land on a 60 stub to make it fit in 2.5" .095 wall driveshaft tube. barely more than a polish. this is also the size of the tube boss on the long spline he bought

rear cv

super short sye

forged 1350 long spline female yoke with a "deep throat" for max flex

34" iirc

yes sir! great way for a high angle and strong front shaft.....then again, at this point I think I would rather have a weaker driveshaft than the t-case........

[blacksheep10]

fuses suck. put a 205 in there (of course you would need a 4l80E and a ford 205 with custom adapter and chebby input in it) laughing

 

[1TONZR2]

fawk that...I dont need OD any more...LOL I am thinkin about switching to a TH400/TH350 whenever I do pony up for a new case of some sort..still undecided on what I want....
