420 cubes and they are Harland Sharp rockers. The Harland Sharp rockers are fine you just have to shim the lifters solid. The way the Gen 3 Hemi oils the lifter these rockers will not work with a Hyd lifter.

Good to see you got it sorted. Were you still using the 1 3/4 dyno headers.

Yes the 751 was with the dyno headers. The 2 inch TTI headers were rubbing on the dyno and we just couldn't get them to fit without banging everything up. I am sure the headers are worth some power as well as if I could get a Dominator on it in the car. We were using a QS950 Quick Fuel carb on the dyno. The A/F was good but I bet a 1050-1100 Dominator would make more power. At some point I may get a Dominator flange Ritter intake and see what it does with a Dominator. I don't have room for an adapter and a Dominator.
