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

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

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

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.
