One rule usually holds true when dyno testing...... the person paying the bill gets to test what they want. The other thing is, there's never enough time to test everything you want.
I think if you went back to my original thread about the TF 240 heads, there are some tests Andy did with this same cam and the unmodified manifolds.
The 270 heads with the ootb 400-3 made 750-ish. Take off say....... 15-20(??) for the dry sump....... call it 730-ish.
Edit: I went back and read through some of that first thread....... looks like with the ootb m1 and the 4500 carb the other motor made 685hp with this cam.
Correct. Some people are forgetting that I've already run 80+ dyno pulls on the 240 heads and have published all of that information. The 240 combo is now a very well developed platform so comparing the very best 240 pull to the first set of 270 pulls isn't going to give you the full picture.
