I think we're mixing it up. The car came to me with a 750 CFM, and I've tuned it as good as I'm going to get without buying jets and rods piece-mill. I'm downsizing to the 600 CFM. I have ordered the 600 CFM but haven't received it as yet. Should be middle of next week. I had modified your quote and got in a hurry (here at work) and left my stuff inside. But fixed now.
Looks like were on the same page! I think your going to like the 600 even though it is a little short on high rpm power. That is how I feel about my 60's on my 360's. Truly, no complaint. It's not a big deal/
