Dyno results and damage report for the 67 Supercharged 331

I went in for a tune yesterday and on the first run I made 483 HP and 509 TQ. After throwing in some more fuel and about 5 runs into the tune I made 536 HP and 525 TQ. At the end of that run I popped out a freeze plug and had to cut the day short. We never even got to tune any timing. I had the base timing set at 10 degrees and heard no detonation at all. I have a 6.87" crank pulley and a 3" supercharger pulley and it was making about 14 psi. Today I am going to install a new freeze plug. Not too bad of a job, I had to pull the header and steering rack to get to it.

Now I am looking for a larger pulley to keep the power down around 500 HP. I figured a 3.12" or 3.15" should work if anyone has one to sell, let me know. DCStang67@aol.com

thats exactly what I am going for. It made that power at 5000 rpm and then started to drop, so there is no need to rev it up over 6000.
