Less than a week after I got the motor running and in the car I got an offer for a free day at the dyno. Local machine shop just got a new dyno and wanted to show it off to a local car club using my motor (which they built).
So, out comes the motor again. Well we started with 488 hp and after 15 runs, tuning with valve lash, jetting, ignition timing, and spacers, we ended up with 517 hp at 6200 rpm and 521 lb./ft. at 4200 rpm. I couldn't fit the mufflers on the dyno so that is with open headers. What I'm most happy about is that we gained almost 50 lb/ft. at 3000 rpm (408 to 446 lb/ft.) That should really make it fun on the street. I'll have it back in the Coug' within a month, I think.
