chain drive with BMS front cover


New Member
Is there an explanation of how to fit a 25500169 front cover to a 153 block with chain drive cam? Cover runs into the chain at the distributor boss.

Most everyone would have used a gear drive with that cover but up until now I wouldn't have thought using a chain would have been a problem. This is interesting and will have to look at one of my covers to see.

Truth be told if you are planning to use a Buick V6 for endurance racing you shouldn't even consider running a timing chain. You need to run a gear drive.
