The motor tune was almost perfect with great idle qualities and part throttle performance for race car. We did some staggered jetting on the nitrous and all the plugs look great. We also played with the timing curve and found 25 hp.

It just all around runs better with NO head gasket leaks!

After weeks of testing and measuring we found the rocker arms are the culprit. The Harland Sharp rocker arms were not designed to use with this aggressive cam. This is why a Jesel valve train setup is standard on all out race motors. This rocker issue has been with us sense day one. Now we have an accurate degree wheel to see it.

No telling how much HP it has been costing us over the years.  L6 motors need there own rocker not a reworked BB Chevy unit. The valve train geometry in a L6 is so much different than a V8. We have a couple ways in mind to fix it and I let you guys know how it woks out! 

Steven….someday I’m going to build a LS1 v8 to see how easy it is!

We received our new Comp Cams nitrous cam shaft and should start
installing it pretty quick. After the cam is installed we’re going back
to Murillo Motors ports for more dyno time.

The 28×10.5 tires are on to stay. We have too much power for 26x 10s and it’s too unstable at high speeds.

I still have one more converter to try and a 4.10 gear set when we find the right converter.

Our new Photogallery is up and running!

A heavy work schedule and Torque Converter problems have kept Mighty6 off the track a lot in 2007, but we’ve got a new set of 28×10.5 slicks and some other changes ready to try out as soon as we can.

We are going to put an anti roll bar in and limit the front end travel to help bump steer. The main problem is that it carries the front wheels over a 100’ before it sets them back down. All that bump steer is tough to drive though, then it gets crazy and tries to swap lanes, check out the vid below to see what I mean.

We put on some wheelie bars. I have to get the front wheels in the air to make stock suspension work so these bars just keep the car or truck from dragging the bumper and crashing down.

They work kind of backwards compared to standard wheelie bars–see pic above.

So, the power glide deal was a success sort of! I’ve always thought a glide calms down a setup. Not in our case it leaves the line with the front wheels two feet in the air. We never got a clean pass because we never got the thing to go straight for 100’+ feet in a wheelie. The last pass it stood up and I had to chop the throttle and it came down hard and bent the front axle and springs. This evening we are going to look at it and evaluate the next step.

I think the power glide deal worked because we found some extra hp. The turbo 350s 1st gear was burned up. That would have something to do with it!

There are also a bunch of little changes we’ve made that may have added a few HP also. Tons of overtime have kept me from racing for a few months now.
