Is that a stock TH350, or rebuilt? If rebuilt, what have you had done to it?

Thanks!

Wow, in the 10s with a mild rebuild. Good to hear that they're that durable. Thanks for the info.

(LSX conversion in progress. 1972 Split Bumper Camaro, 5.3 Junkyard, w/ TH350 and front mount Turbo... coming soon)

finally had a little time to work on car, I got the bottom end back together I put new rings, arp rod bolts (had the rods resized).I gapped my top rings at .028 and the bottom at .034. Installed ls6 cam for now and put ls2 timing chain and a melling oil pump. Also put a set of ebay head studs. So hopefully this week I can get the motor back in car and start fabbing up the hotside.

See, I looked at putting mine there as well, but the alternator and PS bracket I have would put the turbine housing pretty much on top of the ps pump with the corvette accessories I have. Looking good though!
