I researched best I could but still unsure. Trying not to buy and have more no-fit parts and have to send them back. For easier reading I'll refer to them as 4,5,6.

I have a Gen 6 blocks and the cam company sent me a Gen 5 cams. I called and they said to just use a cam button instead of sending them back.

So now I would use the Mark 4 & Gen 5 timing chain, correct? From what I read the Gen 6 cam's bolt pattern is different.

Will a Gen 5 chain fit under the stock Gen 6 cast cover? I read of a slight clearance issue with a double roller when using the Gen 6 cam and Rollmaster IWIS chain. Gen VI Timing Set

Might be easier to send them back and get the Gen 6 cams.

Thanks

I would just get the right cam if you don't want to re-engineer the wheel. Doesn't seem like you have any need for specialty stuff here.

I agree. The cam maker should make this right.

Why go thru the cam button crap if you don’t have to ?

Definitely would not use cam button if I didn't have to. I run Gen VI cams in my 4, 5 and 6 blocks.

Why not just run a stock GM gen VI timing chain set? They are like 82.00 online. It won't rub and it is built like iron.

The cam snout is a MK-IV/Gen V; the GM timing set with the retainer plate won’t work. That’s the issue.

Thanks everyone. I called them back and they are going to exchange the cams.
