Missed on this combo?

I guess we are pretty average together. 423ci/360, 950 4bbl, Victor intake, ProComp heads 280cfm @ .500, 290cfm @ .600, custom solid roller, .600" net lift measured at retainer with the engine fully assembled. 561 lb-ft and one pull at 601 hp. Everything else at 593-596 hp.

Love you Jim because you're honest. Sorry for the cussing but when I get real revved up about something I am 100% confident in-it happens. Cracking an honest 600HP is VERY difficult if not impossible. I know this is getting off track here but this engine is pretty decent as it is. It is soft down low which tells me retarding the cam ain't gonna help Jack and the engine will never recover up top--it doesn't work that way hardly ever. I can tell how good a dyno run is going to be as soon as that initial torque number rolls in. I abort many runs as it is a waste of fuel/time and motor if it doesn't look good right away. J.Rob
