Let´s talk about plan-B. It seems that I can reach my power target also without turbo. The turbo is stil first option becouse it is kind of fun put turbo engine to -48 model car. But, I also have plan-B: Lump port head with 1.94/1.60 valves, flat top pistons zero deck (Santucci book says that using 292 head CR will be 10.5:1), clifford intake with holley 600cfm 4 bbl vacuum and some fine exhaus manifold. BUT, how about camshaft? Street car, everyday use, torgue at low rpm and fuel consumption is important, and lots of power ofcource ;\) There is good information table concerning 250cid but any suggestion this kind of 292 set up?
