Tom and Jim W thanks a lot for the info. I thought that that car had a 250 oil pan because of the gap between the crossmember and the sump. I have very little experience with Holley carbs, I have a 2bbl on the boat that has a custom metering block by the Volvo factory. In a boat half throttle or more is common ,no need to worry about low speed drive ability. Deuce Coupe, the only nonstock things I have is no cat and a open element air filter. I am considering a z28 y pipe, mufflers and tailpipes mostly for sound. The glasspack on there is LOUD. Also when I either get a 2bbl head on or adapt the dual manifold to the head on the car I can run 2 2"pipes to the z28 mufflers. Jay6155
