I would like some expert opinions. I am upgrading my '69 Javelin as follows: '73 258 short block (stock), my existing 232 head with 1.95" intake - 1.50" exhaust valves, 904 Torque Command w/ 1800 stall converter, "20" rear end with 352:1 gears, a possible upgrade from my 390 cfm Holley to a 500cfm Edelbrock, and a new cam. The cam is the issue. I already bought a "Comp Cams - Extreme Energy" cam and kit (not yet installed) with the following specs: .493" - .512" lift (intake & exhaust), and 218 & 226 degrees dur. @.050" (intake & exhaust). This cam has a 111 degree lobe seperation. I bought this cam because Comp advertises that due to an aggresive lobe ramp causing a more rapid timing event, these cams produce better vaccuum and low end and mid-range power than other cams of similar specs. However, I've since talked to a techy at Clifford performance who says that a cam for this application needs to be a single pattern cam of less lift and duration than what I have. While I'd very much like to use what I've already got, I don't wan't to make a mistake either. My goal for this car will be mostly street driven, with occassional trips to the strip where I'd like to have the potential of at least 14 second ET's. Someone like to weigh in on this?
