does any one know whata 350 non-lock tranmission is?
In the later years of the TH350 they put in a lock up torque converter. A non-lock is just a regular TH350
'71 Blazer CST w/ a 400sbc, 4" lift, 36" Supper Swampers, and alot of rust
It's a 350 with non-lockup converter. GM put out a version of the 350 that integrated a vacuum switch and brake overide that locked up the torque converter. This lowered the rpm's at cruising, but only a couple hundred or so, and helped alleviate heat buildup. I have been told not to install one in a fullsize rig, they were designed for light weight vehicles, but GM installed them in larger vehicles with less than desireable results (namely premature converter failure in fullsize vehicles). Hope this helps.
If you didn't build it yourself, how can you call it yours.......?
