Our Vintage Trans-Am club went to chassis dyno our cars on Saturday,4 '69 Z/28's,1 '70 Boss 302,3 Vette's (2 BB's),my car pulled a best-of-event 430.51 rwhp @ 6800 rpm and 389.85 lb ft torque @ 5100 rpm.Chad Golen 383 stroker makes real good power and the Patrick James/Pro Systems built 840 cfm carb is the bomb at making power.Best pull ended up switching to 92 rear jets (76 primary's) and retarding ignition to 38 degrees.Mine's the Yellow Z/28:

Here's a video clip of an earlier run. "Only" 427 rwhp! :)
We had quite a day! Ran 4 69 Camaros, two BB vettes, one SB vette.

Her 73 pulled 366 hp and 414 torque.
She didn't dyno the 73 or the SS this time.
I'll post the vid link over at nastyZ28 for you. I have two or three others I'll give to you on CD Thursday night.
