what will a th350 take?

what should I expect for a th350 to hold (hp and torque)?
will it hold 410 ft lbs at 5000 RPM, 440 HP at 6200 RPM from a LS2?

the reason I ask is I have 3 th350s and keep looking at the ls2 from jegs for my next engine for my camaro

will I need a different trany?

?

its probably getting borderline for a th350 depending on what if any modifications have been done to it.

dreamingdyno2000 figures my 357 should be putting out 380hp/450ftlb and my th350c hasnt had a problem handling it yet...

they hold as much as you build them for. I know buddies running 750hp into them and they last a few seasons at the strip. Mine has held up 2 seasons as well so far.

They'll hold 500hp range with minor mods and a good re-build kit.

basic rebuild and a little cash thrown at them makes them survive at my level, and a ton of cash makes them survive at my buddies level, still cheaper than a built 700R4 though.
