I need some Engine guys here
My friend picked up a 75 about a year ago and now he has the engine out and is working on his engine bay.
But while I was there I noticed that his timing marker is this mangled piece of tin that is spot welded to the timing cover. which isn't so wierd in of its self however it is at the 12 o'clock position I don't think I would be even able to see it if the water pump was on.
What gives I thought there were on the DR. side on the upper corner what am I missing? or is his engine form a different car?
any ideas.

GM moved the timing mark to behind the water pump BUT all the engines had the long water pump, which corvettes did not use, so you could shoot the timing from the top of the water pump. what is the letter sufix stamped on the pad in front of the pass side cly head as this will tell us what engine it is.

I wonder if another balancer from a corvette engine would correct this problem
I think you need a vette cover, not the balancer...But I could be wrong????

gm perf parts sells bolt on timimg indicators that will move the indicator to the side BUT you will have to use a TDC finder and mark a new TDC line on the balancer. :chevy

Balancers & timing covers are a matched set when OEM GM. Whatever you buy, you have to make sure the two are compatible. Just went through this with my own 66 327... the balancer started to separate and was off 2 degrees... had several GM stamped steel covers lying around...they all have different welded pointer locations. Had to order the balancer from GM... no one else had an exact match that would work with the original GM timing cover (and also line up with the rest of the OEM pulleys).
It all has to work together as a team.
