KAAMA said he had the Merlin oval-port heads (2.30 intakes, 1.88 exhaust) solid roller cams and Torqer intakes. We could sit here with Desktop Dyno 2000 and run some scenarios.

No---not Torker intakes. Those 468's had the Dart intakes on them that are now on my 540's. But Crazy is right about the heads-----Merlin oval ports bowl ported with short side radius work. They had Dominators 1050 carbs----heck I don't even use those on my 540's, 9.5 comp ratio, Crower solid roller cams 244*/254* on 110* lobes, Stellings full length tube headers, and the cylinders were "bore notched". Apparently, the Dominators made 35 more horsepower over the 850cfm carbs---but I wasn't there to see the comparison. But I do have the dyno sheets for both engines. With the Dominators both engines made 600hp @5500rpm w/37* of total timing....not too bad for a pair of naturally aspirated 468's!
