i'm getting a 440 kit, mild port, valve work, all around cam, and may run wb rev box with it. i have a stock carb, do i need to rejet it? and my timing chain moved, does this matter if i have it on tdc and the timing sprocket lined up with the horizontal marks?

 

Yes the carb will have to be rejetted . Drop clip down one notch then buy 162-165-170 mainjet to be sure of course you have an aftermarket pipe and take off air box lid and run KN filter with cover.

 

ok thanks what about the timing chain issue?
