    I'm thinking about going with a 383 in the future, maybe 454, but can the th350 handle it? Or does it have to be "beefed up"?

    how well has it been taken care of? are you going to do pull off's with it on the pavement? got a lead foot or do you feather the throttle.

    i got a Th350 behind a mildly built 350. I think a 383 would be fine, a 454 might be just too much for it. smaller BBC might work.
    Greg72 has run a TH350 behind his 396 with no problems (or since i have known him).
    KidJethro burned a TH350 behind his 402 in a week.
    just my semi-educated guess.

    Hmmm, Well I'm not gonna spout of with what it will and won't handle....cause it always seems to be different. But I WILL give ya my experiences. I had a small block 350 and TH350 in my truck awhile back. A VERY tired small block. Burned a quart or so of oil every 2 weeks. lol....I'm guessin like 140 HP...HAHA! Anyways....The TH350 handled that just fine. The tranny had been rebuilt with in the past 2 years. The 350 was getting worse and worse...fouling plugs ect ect...So I swapped in a 402 big block. The TH350 lasted alittle more than a month before it lost drive and 2nd. All I had was reverse and 1st. So now I've got a TH400 in there and all is well so far. Like I said though- Those are just my experiences. Nothin definate. /forums/images/graemlins/thumb.gif

    I had a rebuilt one swapped in 6 months ago, If/after I swap 3.73 gears in my 350 might seem powerful enough lol. I have to keep the poor thing close to floored going uphill so it doesn't lose speed.

    My TH350 has been living behind my somewhat built 454 for 6 months now with no problem. And I do use my right foot. I am very careful not to overheat it however. My buddy had one behind a stroked 502 with a blower and he kept exploding the planetaries apart. He ended up going to a manual.
