[camaro7081]

after having a 260 block ported to a 300 drag specs do i need to have the digital box chip changed or any thing else i dont know about?
box has the 10,500 chip now
i also have the 39 psi regulator will i need to go to the 56 psi?

Which chip is in it now. You'll need to go to an A48 chip for the 39lb reg or the A63 for a 56lb reg.

You can run it just fine with 39 lbs. fuel, but IMO the 56 lbs. set-up is preferrable... Can be a stout engine either way if everything is in sharp tune..
