Hollis, I posted this on another thread on the same subject. The 750ms is just right for you. I had an 800ms holly that I couldn't tune the bog out of. The Demon is snappy as hell and has no bog. I got about the same top end but I am still tweeking it. I am no carb expert but I think you will love it. Here is the other post:
Get a Barry Grant Sea Demon. I just put the 750ms on my 460 and it runs sweet and the quality blows Holly away. Its about $30-50 more than the Holly marine and you can get them from Summit but they are not in the catalog. I think this is the best carb for the money. It works better than the old Holly 800ms I took off--smooth. Billet metering block, 4-corner idle, big float bowls with clear sights, takes holly parts (jets, PVs, etc). Nice! Expect to pay about $500+ but worth every penny.
Jusy my $.02, hope this helps.

Yea..!$560. to be exact thru CP Performance.
Thanks to all.
A guy I know ground the top off his 850 non-marine for better intake...I may try that also.
