I am replacing the motor in my blazer and i found a 4.3 local for sale but the person who is selling it is not sure whats its from. I have the stamping off the from of the block it's ( T0104UHN or T0104UHW or t0104UHH ) the little dots are hard to read. I called my local Chevy dealer but they where not any help. I would appreciate any help


Thanks Mike

Page to ID Chevy castings/engines, etc: http://www.crankshaftcoalition.com/w...asting_numbers

UHH:
1981; 350cid; 165hp; RPO LS-9; 4bbl; C 20; Truck/Van

UHN doesn't show up. Take a look at the casting date to see if it coincides w/the UHH suffix above.
