Thanks.
This is quote from an older CarCraft article about a 440 build with Edlebrock heads using a custom ground solid cam by Lunati.
This shortblock combo is interesting as it's almost identical to my setup with the same KB pistons and 84cc Edelbrock heads.
The 440 build is about half way down the page.
http://www.hotrod.com/how-to/engine/ccrp-0611-performance-engine-combinations/The article and specs look interesting, I like the RPM the max horsepower comes in at and still running 12- vacuum.
"Lunati ground the cam using some lobes designed specifically for the Chrysler lifter. As most Chrysler guys know, the large 0.904-inch lifters allow for faster ramp rates and higher lift without the penalty of long duration times, and Johnson planned to take advantage of this. He wanted the torque curve to be flat, with peak horsepower coming in below 5,800 rpm, so he chose a solid flat-tappet cam with 239/243 degrees of duration at 0.050 and 0.536/0.547-inch lift. The exhaust flow of the Edelbrock head is good enough that a larger split between intake and exhaust duration isn't necessary at this power level. The cam was ground with a 110-degree lobe separation and an intake centerline of 106 degrees.
"On a dyno, this combo made 527 hp and 557 lb-ft. The peak horsepower was achieved at 5,600 rpm, and the peak torque occurred at 4,100 rpm, making over 500 lb-ft from 2,900 rpm all the way to 5,500 rpm. In fact, the average torque throughout the entire pull was 529 lb-ft. Even with all that power, it still pulled 12 in-Hg at an idle, just perfect for the street".
