ok guys, i've finally gotten my hands on a 350 4 bolt main block, but for the life of me i can't recall it it's a 2 piece rear main seal or not. the casting numbers are 14016379 and it's from a 77-79 pickup. if anyone can PLEASE help me asap, i'd appreciate it.

If its an original 79 and earlier block its got to be a 2 piece seal set up. One piece seals started in 86.

 

thank you. you are my hero. i owe ya a big one

 

 

gotta love this forum. i could have sworn it was 86 and up but i wasn't about to send out money to someone without making sure.

thanks again.
