running ... the boat hanging tough on the right of the video is a 94 mph Scarab Panther owned by Forum member Blue Thunder ... We were pace boats for a local poker run ... you can hear and see when it was time to go .

Looks great and nice work!
What size pulley are you running at 5psi? Are you running the 731cam or is that Blue Thunder?

3.34 pulley ... 731 works really well ... last year I upgraded to a custom Teague blower cam ... it's used in the 800 SC ... grind fall's between the 741 and the 651 similar to Cranes 139661 grind

Thanks,
That's to bad no gain. I have the same pulleys on my 250's and finalizing some custom cams this week. Probably run NA for the first half of the season then put the blowers on my 454's. What was your compression ratio if you don't mind me asking?

C/R 9.37 to 1 static with a 106 cc head ... just under 12 @ boost... tuned for 93 octane on the dyno ... timimg @ 30 . Boost @ 4.5 - 5 lbs.

I have a new pair of 3 inch pulleys ... no plans to use them being @ the edge of a 93 octane tune already .
