The car was dynoed just a couple of weeks ago. I felt fairly confident now that I have racked up over 3k miles on the motor. I've had my share of issue to say the least as some of you know. However, with the cam issue solved (now all roller), running hot (now solved), breaking up at high revs (wrong wiring of hood tac).
Luckily, one of the guys in the car club that I just joined works at a local dyno shop. The car pulled some decent numbers but we only ran her once as my tranny has some major issues. We ran her hard though I will say. Took her much higher on the revs than I would ever do on the streets (5500RPM). Normally I'll only hit about 4800-5100 on the streets.
The guys in the shop were pleasantly impressed with the old girl as was I. I was hoping for about 375 rwhp. My engine builder guaranteed me 400 but I did not expect it. Anyway the bottom line is I am very happy with the outcome.
I expect to install my new M21 with the new Hurst shifter hopefully in two weeks. Then we will run her through the dyno once again and get some hard numbers. Once we do so I will post the results with all the stats.
Also, as a result of the dyno run I did have two oil cap (things that sit over the top of the valve springs) break on me. I contacted the builder and he instructed me to remove the remaining caps before any more dyno runs.
