Just for comparison sake, the 261 I just finished building and started last week has a Schneider cam, 492 lift, 280 duration, fairly tight centerline for a good bit of rumpety rump. Relatively large cam for a street motor. Idles at about 800 rpm. 1500 rpm at idle for the bull dog cam cannot be correct. You may have a vacuum leak or something. My distributor is set up, for the time being, at 0 degrees of initial advance. Have you confirmed that you have your distributor set to fire no. 1 cylinder at tdc? Are you sure your timing marks on the flywheel indicate tdc?
