I've sprayed once before out of the hole in 4LO, but it yanked so hard my seat back broke and i ended up in the rear seat area.

Anyway, i have that fixxed and i dont think its happening again. I think the axles are strong enough to take the 4.3L with 75 shot, but I'm not sure about the transfer case.

The reason i want to know is because i have a race lined up against a new Cobra with a smaller pully, exhaust, intake, and a few other things. I think he may run a high 7 to low 8 in the 1/8th. In 4LO i top out at just over 80mph, so is i get off the line hard enough and can get up to speed i think i may have a chance. It would be some awsome braggin rights since this guy is the fastest in town, and if i beat him with a V6 chevy with just a 75 shot.

 

The Tcases are not that strong and were not design for such use. I know a lot of people use 4x4 launches on a 1/4 mile but 4lo lauchs on pavenmet adds even more stress to it yet beyond what it was designed for. You might lower your axle ratios a bit to get better jumps and reduced tcase stress.

 

i know that the HD trucks tcase are rated to 2500 ft. lbs. and they are still easily destroyed(trust me i know) as for a 4LO launch in a regular tcase,I think you are flirting with danger and i would not be suprised if it did not last much longer

 

i would not be doing that in 4lo but 4hi would probably last forever. i had a 4wd 90 s10 blazer that i put a ZZ3 crate motor in(v8 aluminum heads, roller cam) and hit that with a 125shot in 4hi and it took that many times. got it into the 13's wich wasn't too bad 10 years ago.

 

the auto track is rated to some thing like 2200ft lbs. the HD case is rated to 5500ft lbs.

 

It is a Auto track, and the 4.3L with all my mods and a 75 shot will probibly only have 320RWTQ. So it should last through a glory run right?

 

try it, if it holds you have bragging rights, if it dont just go to a junk yard and pick one up for $100

 

Those babies are chain drive on front axle and that will stretch and break with time from such use or the planataries will fail, take your pick.

 

snake eater i think you should go for it. just make sure you got a video camara handy.

 

Sure why not but who will pay the repair bill?
