my back of the cigarette box calc
12a std at flywheel is 100hp. Assume 17% drivetrain loss and engine age, thats 83hp on the wheels. I'll give you 10% for the street port, 10% for the holley and 10% for your exhaust system. So thats 83 x 1.3 = 107.9 lets say 110hp on the wheels.

110RWHP is a little low. My '83 with a mild SP 12A, stock intake/carb and factory exhaust manifold w/ free flow exhaust pipe/muffler made close to that. It also gets 24-26MPG hiway, 20-22 city/hiway combined.

I'm going to say about 128 atw. It just sounds like a lonely number that doesn't get used much, and I felt like giving it a little attention because of that.
