Yes, this was on my current motor. I am at school and the dyno sheets are back home,but it was somewhere around 20 hp I picked up.

I was disappointed in the numbers too initially. With the GT-40 heads and intake, B-cam, 70 mm TB, 73 mm MAF, headers and such, it was only making about 240 hp. Although, when I think about it, this motor was advertised at something like 285 hp when I bought it, so my numbers may not have been too far off, depending on the exact set-up they used to rate the motor with.

The dyno guy was kind of puzzled though. A very similar car to mine was making ~270 hp at the wheels, except he had the 1.72's. So, we slapped them on mine and up went the numbers.
