Help me settle an argument

I used to run a 650 dp on my 360. I put a 750 Proform main body in it and it picked up 3 tenths and 3 MPH....no joke. If you have a 100 bucks to spend, I would put Proform main body in it. It only takes about 20 min to install too. I still use that same carb today on my 410 stroker...see sig for times.
