[ERA Chas]

Todd,
For professional help with Holleys, I highly recommend you call [or visit] PMR Performance, in Kensington Ct. Probably very close to you. Phil Molski is a first class, hardcore machinist and engine builder. Phil has reworked my twin 600's and Era-FIA's 780 into killer carbs with great manners. Phil uses a carb flow bench and now my 600's are 652's. Also you guys looking for an engine-builder in the Northeast should contact Phil, who just may be the best-kept secret in New England. Quality guy who's easy to talk to. If you need more convincing, ask Bob Putnam, Rich or Doug at ERA about Phil. His phone is 860 828 8828.
Hope this helps,
