How is this cam for 470

No more heavy font,Mope. Anyway Rumblefish I bought the heads bare done, for the price of a solid roller camshaft,and the ferrea valves, springs,machine work, rest didn't kill me, but if I had as cast 906's it would have cost at least 1,500 or more. I did good,real good.So believe me, I'm a shoppin fool and I don't want to go 10.50s only 10.90s So I think in a A body I can do it with an hyd. and a bunch of torque. highest gears I have ever ran is 4.10s and my last 10 sec car had 3.55's I am a torque buildin fool! I like the idea of 550 hp 650 ft pounds if it can be done...Mope, anyone can go fast with a 270 dur@050 solid roller, duh. The object is to go fast and NOT spend a lot of cash!!! Am I right or wrong? But 285@550 isn't that small its not 220,my 406 chevy made 611hp with 285@600 lift AFR heads 2.05in. 1.60ex valves.......but double the 285 and u got 570 might be right might be,so now do I get rid of the heads or keep them?The guy I bought them from said at least 285@550 maybe I should get them flowed and know for sure. They could be 305 some guys have a cnc program for the 906 that gets 305+ think it was Hughes ?maybe I will let my wife proof read my writing as shes a proof writer,and knows where to start a new paragraph................I do build fast engines ask anyone with my stuff NO COMPLAINTS.........
