Well, I'm heading down the downward spiral.

How much play is accceptable on a SBC timing
chain I have about 5/8 inch side to side in mine?

Does the merc mag 350 (O.E. hyd roller vortech)
have a double roller chain?

My motor has a single chain with a plastric cover.


Thanks again

Seems like a lot of play.

You really need to check it by hand cranking the engine, watch a valve on the lift cycle... After you move it up a bit, hand crank backwards. pay attention to how far you have to turn it backwards until the valve starts moving the other direction.

Make sense? it seems hard to explain over words online:boggled:

5/8" is unacceptable
