Cam is crane HR #689521 and a lift of .509int/.528ex with duration at .050 of 222/230..... Nice bump over a stock cam but still mild enough for power brakes..... Andy used the .528 mopar solid and it was the best cam of any he tested for use with the HP exhaust manifolds.....

I should also mention that I will be using 1.6 rockers so that puts my lift up around .540/.560. the Mopar solid has a lot of lash at .028/.032 but Andy also used 1.6 rockers so I should be around the same effective lift and my cam shows a little less duration at .050 vs, the .241 of the solid cam but the same adv duration of .284 on the intake and a little more on the exhaust at .290 vs. .284 The power range of the cam is 1,800 - 6,000 so I am sure I am giving up some power as opposed to headers but I am trying to max out this combo for use with manifolds and I think I have done my homework and have about the best combo for a dual plane sixpack intake using manifolds.... I want to look and sound stock and make people wonder how they got beat by a "stock" 440 sixpack!
