Another shot of the finished heads... See how beautifully smooth those exhaust ports are? No bumps, and LOTS of added flow...I can't wait to get dual exhausts and see how well it runs!

These are the stats of the cam that I installed: A Comp Cams XE256H. I also purchased CompCams lifers and pushrods and Crane rocker arms. I had decided to go with all new hardware, as I have no idea how many times the originals had been torqued and re-torqued, but I made one mistake... *NOTE* DO NOT THROW AWAY ROCKER ARM BOLTS! They are not a standard size and are $2.50 EACH LIST PRICE from GM... I could get 1/8" longer or shorter....--a word to the wise. I went to a Larkin's Pontiac-Cadillac-GMC in Tomah, Wis. for my hardware needs. The "other" GM dealer in town wouldn't bother looking up the bolts, but the friendly Parts Manager at Larkin's looked up a dozen or so bolts, studs, and other engine hardware odities for my project.

This is the desktop dyno stats for this cam and engine, thanks to J & S MACHINE and Jim Lapikas. Originally, I had wanted a modern grind equivalent of the W-31 cam, but this cam was so radical that my power brakes and a/c would not be able to work! This cam has more lift than the W-31 cam, but not as much duration. I ended up with more horsepower and torque, but the peak horsepower comes much lower in the hp curve. The W-31 depended on high end horsepower and 3.91 gears to make it go fast. Though I'll have more horsepower and torque, my 3.08 positraction gears will make it difficult for my car to be very quick. It will, however, be pretty nimble!
