Puzzlescort is dead on the money.
Realistically 113rwhp is getting to the maximum power you can extract from a single dual throat carb - just simply can not flow enough air to produce more power. Keep in mind that if you are chasing 130rwhp with a NA 8v Pinto head that you will ultimately be sacrificing low down torque for absolute power - up around these numbers she will be a bit doughy below 2-3,000 rpm and will drive you nuts in traffic if she is a daily driver.
Don't get me wrong, it can be done but reliability and driveablilty will suffer. If you are chasing these numbers and you still want to maintain daily driver flexibility and reliablity you really need to be looking at either a 16v Sierra head conversion or forced induction - but of course that depends on your tolerence levels for driveablilty and the size of your wallet.......
Cheers
