After four sets of pistons Craig and I decided to call it quits on the N2O. Not long after we decided to change the combination we found out why it was hurting pistons. A JE piston rep confirmed the pistons were under engineered for the power level. This caused the pistons to collapse over the [...]
Here is a little tease on what is in the works. The finished product should be in a couple weeks. Shortly after that we are off to the dyno again.
Stay tuned M6 fans!
After the so called close call on the timing issue it was apparent M6 was wounded. We pulled the motor down for closer inspection. We found the ring lands pinched on all the pistons.
A fresh set of JE’s pistons are in the motor now. We did some port work to the head and raised the [...]
We went to track and make some test passes to see if
the crank trigger deal was fixed. Yup, that fixed it so we are ready to
go now. One of axle tubes split on the rear housing so we need to repair
that or replace it.
Now another thing to deal with is our fuel supplier, Torco, went [...]
After the dyno session we added a 140 amp alternator to the truck. We
went to San Antonio Raceway for a TNT session. The RF’s from the alternator
screwed up the crank trigger pickup.
The result was all the grounding straps were burned off the spark plugs. We though we hurt it good, luckily it is OK. After rerouting the [...]
On Mike Murillo’s dyno M6 thunders to 650 rwhp @ 6300 rpm and 547rwft @ 5700 rpm with a conservative 325 hp shot of nitrous. The cam shaft swap proved to be the main ingredient for the EFI the show its full potential.
The motor tune was almost perfect with great idle qualities and part throttle [...]
Guys, it has been a while since I updated anybody. We managed to get the long block together and degreed the cam. That is where the trouble started. We have a new highly accurate degree wheel and found the valve timing to be way out.
After weeks of testing and measuring we found the rocker [...]
Here’s some photos of our cylinder head with the new head bolts added — it is already at the machine shop. Arrow Machine is prepping the head and honing the block as well as a few other machining chores.

The Mighty 6 garage has a new addition. This should make the converter swaps a breeze along with other maintenance chores.

Now that the ADRL series is over for 2007 we can now concentrate on the truck. The block and head is already at K&S Machine for the needed head bolt upgrades. We are doing some testing on a spare head for proper head bolt placement of three more studs.
Whew, been awhile since I’ve had a chance to post any updates. Long hours at work and helping a buddy run his Outlaw Pro Mod (see pic–that’s me on the right) have kept Mighty6 parked for now. More updates to come later
After testing many 8″ TCI converters it’s time to step up to a 9″
unit.
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.
Well, we have been to the track 3-4 times changing torque converters each
time. We have a 4200 stall now.
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 [...]

A heavy work schedule and Torque Converter problems have kept Mighty6 off the track a lot in 2007, but we’ve got a new [...]
We took the truck to a local street car shootout race this weekend at Houston Motorsport Park’s 1/8 mile dragstrip. We were runner up in our class. We were on a pretty fast pass in the final round until the truck decides to change lanes about 500’ out. It was a pretty tense moment to [...]
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.
Well, we went to Houston Motorsport park this weekend and tested the new power glide setup along with the other things we did. The new damper gave it such accurate timing. You can hear the HP gain from it. The motor sounds so much cleaner.
So, the power glide deal was a success sort of! I’ve [...]
A heavy work schedule has kept me from updating the web site regularly. We’ve installed a Powerglide transmission and a new harmonic damper for more accurate timing.
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 [...]
