I have 64 Fairlane with a 289 with Performer 289 and Super Comp headers, C4, and 3.25 open 8" gears on a 24.5" rear tire. Ultimate goal is to run 12.99 or faster while still having a steetable car. I have been lusting after the Comp 281R retrofit hydraulic roller, but this is a little pricey. (Specs are 0.512 lift, 281 advertised duration, 110 lobe center, and 61 degrees of overlap.)

I just stumbled across a heck of a deal on a Crower 15000 solid flat tappet with similar specs. Specs on this cam are 0.465 lift, 280 advertised duration, 110 lobe center, and 60 degrees of overlap. Is the Crower cam something that can work with my current combination? Future plans call for Windsor Jr. heads, and either a Performer RPM airgap or a Victor Jr. I will also be swapping in a T-10, lower gears, and bigger tires, so no desire to play with torque converters. Another twist, I have the Granada discs and a power booster sitting in a box, waiting to be installed. Will I need a vacuum can to run power brakes with this cam?

That cam has 240 degrees of duration at .050 lift and 108 degrees of lobe seperation. It won't make enough vacuum in a 289 for power brakes. The 15308 cam just above it would perform better as it has more lift, a faster opening and closing rate and slightly less duration. It's still big though. Both these cams will work good from around 3500 or 4000 to at least 7000 RPM in a 289.
