ok dont know if i deleted this post by mistake or not but here my question when i time the truck with a timing light i put it on the number 1 exhaust and unhook the vac line the time it with the disturber get it where the mark needs to be the tighten the disturber down and rehook the vac line and she should be in timing right

The intake is what should be used. Pezi reminded me that the intake is the primary.

but everything else is right on doing it

i don't really know for sure if using the exhaust side would hurt your timing at all... but the intake side is the primary

Yeah everything else is right.
