Block casting # ?? Joe ?

[Ray G.]

Hello;
Have a block casting # "1088548" the 1 could be a 4 or ?
This number is on bell housing flange, right side if the distributor.

No code(decked) in front of the right head.

Think it's mid seventies 350 ? Don't have it apart.

Has a weighted flywheel, but a smooth circular 7" dampener.

Trying to identify the block and wondering why the weighted flywheel. Looks like a 400 weight.

Your help is appreciated.

Thank you.
Ray

Hello;
Found online the casting #14088548 is 86-94 350ci. My interchange books aren't that new.

BUT, still need to know why it has a weighted flywheel.

Your help is appreciated.

when GM went to a 1 piece rear seal the had to remove the little counter weight on the rear flywheel flange so they added it to the flywheel or flex plate for balance

For a moment the thought was we had a can of worms.
