From my standpoint it is hard to say what is happening due to lack of specs.

535 ci

1) 920 HP (what RPM), 278 intake and 292 exhaust on a 114 cl (what LSA), what heads (flow and valve size), what CR

2) 870 HP (what RPM), 284 intake and 306 exhaust on a 113 cl (117 LSA), what heads (flow and valve size), what CR

Do run a power adder on this engine?
