I found a long block 33970014 ss 70s code, I was thinking to use in my no performance work truck 85 long bed....I pulled original motor already, th350 is still in truck.....I tried to get codes off th350 but all I see is a label on right side ( 203 88 LBA- 35530) then on bottom under end close to tail shaft is (1c 6 198
1d 6 198....sorry I wish I could post pic....
