As most of you know, I had a 4.6L 2v GT engine in my car to start with, the stock motor. In November of 02 I had it dynoed, not much really done to the engine, a few bolt ons here and there, this was my dyno,

Decent torque, oh and that was though an automagic trans.
At VIR in Feb of 05 I blew that engine up, hole right through the piston, anyway, replaced that with a 4.6l 4v from an 01 Cobra, never had it dynoed, my lap times were lower at Summit and VIR than with the 2v, but I had changed the entire front suspension while I had the motor out and I had recently put in a TKO 5speed.
Well, first of this month I had the Cobra engine dynoed at Carlisle, in front of about 300 people, I was NOT impressed.

Something's f'ed up there!!! The data log showed my timing was WAY low as well.
We goto watkins glen anyway, Pete and I run together, you all saw the videos, I couldn't pull on him, we were pretty much dead even on the straights.
I get back home and pull the spark plugs, #7 is COVERED in oil, oh great, wonderful, this is great timing, 1 month from Hyperfest and I will probably have to rebuild my engine. I call up a buddy of mine that builds 4v drag engines to come over and look at it, while he is on his way over I start pulling the top end of the engine apart (yes, I took it out of the car, can't get the heads off w/ it in the car), well what do I notice? The #7 injector that is directly under the throttle body is UNPLUGGED! OMG. WTF! So I leave the heads on and my buddy gets there, we have a good laugh and I'm still flabbergasted, it has been unplugged ever since I put the motor in. I already had the cam covers off so he degrees my cams for me and resets the timing (left bank was a few degrees advanced). He checks the #7 piston out w/ a borescope then we do a leak down test, holds great, no problems, phew.
So, I put the motor back in the car (total elapsed time, 5 days). I finally got the exhaust redone and the car back down on wheels and arranged to have another dyno done this morning early, here's the results,

hock: +50hp +50 tq
This motherfucker is going to be a handful at Hyperfest 8)
