Re: Bad Head Casting Numbers?
Yeah that is what I thought. I knew the 920 heads were not very good and that the vortecs would be superior. Pretty much everything I know of what to do with heads comes from John Ligenfelter's book on SBCs. That book was written just before vortecs were around. He too talked about how bigger valves aren't neccessarily better. What I have had in mind is a motor similar to CHPs Impersonator motor that pulled 428hp with 525fllbs with nothing more then new springs, a .480" lift 230 degrees of duration with 109 degree lobe separation. single profile cam, and some more little goodies. It was a 406SBC, so I am not expecting to get exact torque numbers out of my 350.
