I got the unit for a good price and it's in nice shape, even if I am stuck with it, I can clean it up and probably make a buck or two on it.
It is a small block, 436 with 15 degree heads. The 2 1/2 runs neutral on the flow bench without shafts and butterflies. I was going to see what it did with the shafts and butterflies in this weekend but I just don't feel like running down to the shop. If it comes down to just profiling the shafts and thinning the throttle blades then it's a no worry situation.
