Im putting my engine back together and have a question on timing. When the mark on the crank gear and cam gear line up does that mean the number 1 is at tdc. I bought a tdc finder bet when the pistion stops the 2 marks on the crank and cam gears do not line up. just want to get this figured out before i get it all together.

THANKS a lot.

 

No. TDC #6.

 

So if I keep it at that spot and set the distributer to #6 I will have the correct timing. Any other help on setting timing would be great.

THANKS a lot.

 

Yes. I've done several GM V8's and after aligning the timing marks and installing the distributor at #1 it always backfired. Pulling #1 plug and putting at TDC compression stroke I was 180 off. I couldn't believe I was making that big of a mistake. If you read a MOTORS manual on the GM timing chain it says it's at TDC #6. It was a surprise to me. What I like to do is, if the dist doesn't drop all the way, is take a long screwdriver and turn the oil pump until the dist drops all the way and is pointing to #1 (or #6 if you want to keep the marks aligned) on the cap. I don't like to crank the engine to fully install the dist. If that helps.

 

THANKS a lot for the info. That will make my assembly much easier. Will possibly attempt to start the engine tomorrow since im waiting on my timing chain cover to come in.

THANKS again.
