Any one have the measurements for different carb mounting patterns? I would like to know the spacing of square bore flange, Dominator flange and spread bore flange mounting holes.
Also in relation to throttle bodies. Can they be too big. I know that if one is too small it can cause problems but what if one is too big. I know that the stock carb for my 472 flows in the range of 750cfm. Holley makes both a 1000cfm and a 2000cfm throttle body. I have a lead on a 2000cfm unit for less than the price of a new 1000cfm. Would overkill in the flow of the throttle body cause any tuning problems?
Thanks,
