gear drives
 

overkill for a 600hp 540? if so what timing chain does everyone use?

Cloyes double roller will do the job just fine

Yea, But gear drives sound so cool!!!! I have them in a stroked 388 in my Toyota and in my big block 69 Chevy truck. might just have to put one in the 557 in the boat!!! Cool, So very cool!!

They sound cool but they are hard on the valvetrain.

What he said and costs you about 30hp on a small block. I'd rather go fast than break parts and sound cool. Cloyes all the way.

Rollmaster makes a nice timing chain set.

robs H/P...worthless if you not driving a cam driven fuel pump....

I agree. No reason to run them in a boat. Personally, I run a Jesel Belt.

Cloyes,true roller billet timing set..
