Congrats on getting it up and running again. I hope to eb joining you soon enough. If not with the good motor we will toss in the back up mule.

Ok, finally got all my ducks in a row and ready to post.
First things first, please bear in mind that we can compare todays #'s to the highst #'s got got last time. Those pulls were made with a 2" APD spacer and we completly forgot about that untill we were tearing it down.
So, for a fair comaprison of an apples to apples test, Here is the best dyno sheet On alky that is as we ran today.
The only other item to mention, and I was not aware of it till this afternoon, is that Scott decided to install the cam 3 deg adv from where it was last time. So instead of a ICL of 108 we are now at 105.
His thoughts behind this change were to increase the exh piston to valve clearence, and bring the power band down in the RPM range all in an effort to avoid the bent exh valve problem we had.
Here's the 2 warm up passes we made with Scott's dyno gas carb and C 12

This is where it gets really cool.
For this next pass the ONLY thing we changed was the coil. We swapped out Scott's HVC coil for the brand new FIRECORE coil I picked up from Sparky. Even Rick thought the HVC would out perfrom his coil but boy were we all surprised.

655 hp @ 6000 625 ft lbs @ 4900 with the HVC
662 @ 5900 633 ft lbs @ 5000 with the firecore
7 hp and 8 ft lbs just from swapping out coils
Now, on to the alcohol.

Pulled the timming from 35 to 33 degrees

Back a little more to 31
http://www.youtube.com/watch?v=UJY1r7XxafY
Back up to about 32.5

After seeing the torque #'s on the last pull we decided to leave it there. Yeah, we gave up some upper RPM HP but gained much more torque and got a nice flat curve to boot. Not to metion the piston to valve clearence gained as well as the the less wear and tear on the valve train. Neither of us wants to go back in to it anytime soon.

that is a nice improvement in the torque map.. not terribly far on on the hp graph...also.

Thanks guys. I greatly appreciate you putting up with listening to me remable about this.
Jamie, we have some better springs in there so we should be alot better off than before.
Marco has the #'s and last I heard both conv were opened for inspection. Should be a far cry better than the last time out.
And now,
onto the lighter side of things
