Sorry to revive this thread, but I didn't want to start a new one. The 350 has yet to be pulled from the truck, so I have no progress updates thus far. What I would like to know is how much trust can be put into the TH700 currently residing behind the tired 350. Both pieces have over 320,000 kilometers on them. I am interested to know because it turns out my dad is not quite willing to let the engine go to me yet. He wants the 350 rebuilt, then put back in front of the untouched TH700. I have a gut feeling this is a bad idea, due to the high mileage, (not to mention I want the darn engine for my CJ). I know these GM transmissions are tough units, but does there come a point where one should start to be weary of the remaining life of a TH700? Especially when put back behind a rebuilt performance oriented 350?
->'79 CJ7 (VIN Says it's a 5, wheelbase says otherwise), 6 inches of spring lift, awaiting an MC2100 on a teamrushed MSD'd 258
-->350 time. '95 block SBC, stroked to 383, dremeled heads and big 'ol intake, maybe a Holley 750 CFM, not sure yet
--->"Safety? Buy a Volvo. Never buy a CJ, or a Chrysler Jeep knock off, for safety, fuel mileage, reliability, handling, ride, comfort, aerodynamics, quietness, convience, stability, low maintenance cost, performance, or ease of use. The only reason to buy a CJ is because you are absolutely, incurably nuts." -OldTexas
