I am unclear re: Thrust bearing, Cam button, and distributor gear for the combination of of using gen VI ( HP-500 Cam in a Mark IV ( 365 magnum ) block. I am using the single roller chain ( stock Gen VI - I think ) cam gear and chain. So I believe that I need a cam button..
Do I also need the thrust bearing with the gen VI timing gear?
Do I have to change the distributor gear to bronze?
I believe that the HP-500 cam is a crane cam....

Darn it... I find this out after I installed my timing cover and glued it all up to the oil pan..... Geez...

Thanks very much for any help anyone can offer to clear this up for me...

Hey folks,
I'm just wondering, am I stuck using a cam button??
Thanks.

I run a gen VI block with a gen V timing cover with a cam button. You have to tap the block for the Gen V timing cover because it has 10 bolts instead of 6. I'm not sure how the cam button works with the gen VI cover. Talk to RMbuilder he will know.

Swede,
Thanks for the reply...

i believe comp cmas makes button for this application
