THE FIRST ONE IS 305A AND THE 2ND IS A 305E. John

Re: Timing chain set
 

The one you have is the same as the one I have on the 305A. John

Re: Timing chain set
 

Sorry, the one you have is the one I have on the 305E. John

Re: Timing chain set
 

Mine is a 67 305E. The timing set I got from O'riellys.

Re: Timing chain set
 

Yes, The 305A has a single groove gear and the 305E has a double groove gear (sprocket)
Thanks, John

TJ'sGMC, not to confuse you, the one you have is the same as the one I have on my 305E and I have a complete new set-up already for the (E) motor. Can I use it on the (A) motor, I am changing both gears and the chain. John

Re: Timing chain set
 

Use the setup from the E motor along with the E motor eccentric and fuel pump.:thumbsup:

Re: Timing chain set
 

Thanks for the help. What do I use for an eccentric on the E motor when I rebuild it. I can get another chain set but it's the eccentric I would need. John

Re: Timing chain set
 

What you will need is a 1966-74 GMC V6 eccentric, yes they are the same for all the newer V6 engines from 305E, C, 351C, E & M, 379, 401M, 432 and 478M V6.
