I have purchased a 493/440 kit from Mancini along with a pair of aluminum Stealth heads from 440source. I plan on running a Comp Cams XR280HR-10 extreme hydraulic roller that specs of 280/288 advertised duration with 541/537 lift with 1.5 rockers Harland Sharp roller rockers. The power band for the cam is from 2200-6000 so I want to run an Edelbrock Performer RPM manifold and a 800-850 cfm carb. Hooker will supply a set of Comp headers with 1 7/8" primaries and 3" collector. I am hoping for a mid 500 horse motor on pump gas with a freindly 10.5:1 compression ratio. It will be going in a 1966 Plymouth Satellite with a 727 torqueflite, 2500-3000 stall converter, and 3.23 gearing in the 8 3/4 rear. Do you think the recipe could be good for some 12 second passes?
