Yes, Hot Dang! I got the call from Fastlane Machine that our 489 is done!
Wasted no time and beat feet right down there to grab it. I’m thinking anything north of 500 horsepower with a gob of torque would certainly be a win for our C10.
Here’s what the Go Fast Math horsepower calculator thinks.

Stage 2: Dual Plane High-Rise
Intake duration @ .050: 221
Tappet type: Roller
Dynamic compression ratio: 8.83:1 (best guess)
Engine displacement: 489
Cylinders: 8
Peak intake flow in CFM @ 28” of water: 320 (best optimistic guess)
Same as last time I need to grab just a few small items (distributor, block off plate, etc.) and make an appointment with Kidd Performance for a break-in and dyno tune. Then we’ll see just how close the calculator comes to the actual figures.
