Anybody ever weld up the spiders on a 7.25 cus thier a chepo like me... whatd you put it behind, how hard you drive it, and how long did it last, and what breaks next... thanks in advance...
I agree but a rookie will be 6 hours.
lol somehow my quotes were not as fast as I was posting lmaoOk, who did what here?
I posted this in the "heater smokes up the interior" thread.
Kinda what i thought... less it was a bearing or sum... how much abuse did ot take before it went... i take it you abused it pretty good behind a 318 or 360?...I have done it for mud in a demo derby the next weak spot is the shafts.
Lol... no akin off my backlol somehow my quotes were not as fast as I was posting lmao
What is going to make it break a shaft is on turns both shafts do not turn the same speed. Slow on turns and it may make a few burnouts. lolSo i can just assume itll be fine for driving around town and doing burnouts? Untill it decides it isint ok anymore and snaps an axle... yea?

If i weld it theyll go the same speed, which is the prob... lol... i get what ur sayin tho... straight line burn outs and try and stay out of it around hard turns...What is going to make it break a shaft is on turns both shafts do not turn the same speed.

Sure you did Beast.... Sure you did....
Now go take a short nap and everything will be ok when you wake up.
Getting old is tuff.... Lol
Hahah... well... now that ypu had a nap, and since your here, how long you think an welded 7.25 will last?...Ok, so I went and took a nap and it didn't help.
Something got crossed with another thread somewhere, and I'm not EVEN going to try and figure out where.
I even have proof.

I think it's kind of a once done it's on it's way to being over.
I feel it... your kind of sign its death warrent from the start....on the other hand, people practically give em away, even if i go thru a couple it probly wont cost me close to anything... itll probly give out if i ever get that 360 in there though...
Hahhah... the c clip thing got me. I had not thought about the sprag. Its just a 904. If i recall, bad sprags can lead to exploding torqflight syndrome... but a 7.25 on tired old springs shouldent be too dramatic if it snaps an axel... it wont do the chevy "pull out" thing if it snaps will it? (Like with C clips, lol).... my wheels not falling off or anything crazy?You might keep in mind that breaking a **** rear end can ruin the sprag in the automatic, "if that's what you have."
Actually, "in the old days" a friend of mine broke the 10 bolt in his 65 Chevelle, and after we got the axle replaced, we discovered THE MUNCIE 4 SPEED INPUT SHAFT HAD SNAPPED
This is the guy who later was the first owner of my 70 440-6 RR. When I arrived at Navy Electronics "A" school at Treasure Island in the fall of 68, and eventually made my way to the then fantastic amateur radio club, K6NCG,
(Some photos of the club here

here sits George's 65 Chevelle. "It turns out" that he had bought and junked out a low miles wrecked 67 350, 4 speed Camaro. So now the 350/ 4 speed and Rally wheels were on the Chevelle
"Sometime later" after we had become friends, he was (as usual) building up the muscles in his right (throttle) foot, his left (clutch) foot, and his "shifting arm" ..........getting onto the San Francisco Bay Bridge leaving "the Island" and broke the rear axle going into second gear off the on ramp.
We coasted for awhile, "dived" into a turnout on the bridge just as the rear end locked up. There were 3 or 4 of us in the car, I don't remember. Two of use jacked up the car and got one rear wheel setting on the spare tire. I crawled under and removed the rear cover. The C clips fell out as we tried to gut the thing and get it to turn, and neither of us!!! knew what the C clips were for!!!
So here comes the tow truck, who decides to PUSH US down off the bridge. As we went down the ramp, an horrible rubbing of the tires insued!!!! Of course there ARE NO BRAKES because this is before dual master cylinders!!!
But George is a pretty smart guy, and already had a "line lock" on the car. He pushed the button, and "stabbed" the brakes a couple of times to build a bit of pressure in the fronts..........and we rolled to a gentle stop at the bottom of the bridge!!!
Tow truck went around, hoisted the rear, and towed us all back to the island!!! LMAFAO!!!!
We bought a used 10 bolt at a junk yard, and put the thing in. Started 'er up and IT WENT NOWHERE!!!
NOTICE this photo of a Muncie shaft I found on the www

NOTICE the groove around the shaft splines........I know not what they are for, but that shaft BROKE RIGHT THERE in that groove just as clean as could be, and !!!POOF!!! we have a 'free' alignment tool for putting the clutch in!!!
Yes when an axle shaft snaps it comes out on its own with a 7 1/4Hahhah... the c clip thing got me. I had not thought about the sprag. Its just a 904. If i recall, bad sprags can lead to exploding torqflight syndrome... but a 7.25 on tired old springs shouldent be too dramatic if it snaps an axel... it wont do the chevy "pull out" thing if it snaps will it? (Like with C clips, lol).... my wheels not falling off or anything crazy?
I never opend up a 7.25 before... i didint realized it was a C clip deal... that kinda blows... i might still do it anyways...Yup. ANY C clip axle. You either break an axle or break something that "removes" the clip it will come right out.
7.25s are NOT C clip rears...and welding one up will increase its strength tremendously.
Moderate weight car...less than 3500 wet, less than 300 horsepower and auto trans, it should last a good, long time.
