Holley 600 Double pumper on a stock 318 Auto?

Running around normally won't be a issue because your on the primaries only. Now, going WOT from a idle would probably be too much. But with a little practice you'll get the hang of rolling into it instead of slammin' her wide open. I don't see why you couldn't live with it for a time until your ready to booster up. Gearing and stall speed will determine how good/bad it acually is. And it's only a 600 so that helps also. Just my opinion:D.
