Don't know whats going on in the garage but no one seems to be able answer this simple question. Truck specs are: '85 K30, 454, 400, 205, 60, 14, 4.10, 4" front and rear springs, 35" tires. 454 is mildly built with a 260 Comp Cam with .475" lift. This cam is a dog. Rest of engine has an Edelbrock intake with an Edelbrock Q-Jet, Hedman headers, dual Sonic Turbos. 400 is all B&M built. Shifts good and crisp. Stock converter. I'm looking at Lunati cams. I've selected one that I want to get more power and speed from. I don't want to change converters. I need someone who has the program-thingie to let me know what I can expect out of this cam I pick here: 292 degree advance duration, .544" lift, 2000-5500 RPM range. How will this cam perform on this truck? I'm not looking for a tow hauler or fuel economy. I'm looking for POWER but not too outrageous. This cam part number from JEGS is 638-00024LK.
