Figures

Some interesting figures you post there. I don't mind too much cruising at 70 (although it's hard to stay at that nuber)and 3200 rpm. The rpm's go up tooo much for hourly runs involving 75+. With my combo, I'm looking for pit stops at 250 miles of before.

You Gonk'ed this setup for me in the early stages of engine planning, and I sorta built it around several of your estimates.

It's a +.040 390, forged pistons, 10.7 comp, ported/polished/milled heads, Hooker super comps, 2 1/2" mandrel exh sys with Dynomax turbo mufflers, tri-power, solid cam is: 240/240, 570/570, 108*, installed 2* adv, solids set at .021/.021 with the proper rocker assy., blueprinted mech adv dist, engine is balanced/blueprinted, timing is 18/38 I believe, 8 qt pan with dual remote filter and other stuff too that I can't think of at the moment. Plugs look very good running Autolite 32's, but the exh is blacker than I like, so I suppose I should rejet the carbs this winter. Hate to downsize the jets because it never loads up, idels great at 1k and really, really does well in mid to top end and never hesitates a second. Hope this info helps some... Thanks Werby.
