hey everyone.

im rebuilding a 350 block to pun in my 71 nova. its my first rebuild so its really rewarding to see the whole thing come together.

i was told when i first started that if i was going to try to do it myself, to get ready to take it apart and put it back together a few times before i get it right. well..

i haven't had to do that yet, and hopefully i can get out of this jam im in.

i just finished short blocking it yesterday, the pistons, crank, cam, timing chain, i thought it was all ok. i didnt put in the rear main oil seal in!

the seal is one round peice, rather that the 2 peice seals that i seen in my summit mag. anyway..


do i have to take my block apart in order to install this?
you didnt say if you had installed the pan or not, but there should be a plate in the rear of the motor that holds the seal. 4 bolts bolts it to the block and the rear pan studs are screwed into it. the best way is to take the seal retainer off of the block , tap the seal in and bolt it back up, but you can tap the seal into the retainer while its on the motor. hope this helps
