73 340 timing chain

[randy73]

Can I put a double roller chain on my engine without having to mod or replace the cover?

 Yes

I don't remember if it was small block mopar or not but sometimes going to a double row timing chain from a single row you have to make sure the fuel pump arm has the extra jog in the arm to clear the extra width of the chain or is that a different motor entirely?

I believe all 340's came from the factory with a double-row timing chain.
