Maybe we should put an ad in 'National Inquirer'...you know,,"inquiring minds want to know.."




After a long day at the track today, our transmission broke after the 3rd time trial so Denny and I had plenty of time to discuss "Fred Chapman, CSI".

Fred, I know you stated that the engine was running at 19*s @ WOT, but how did you determine this?




The ignition is the MSD Hemi6 setup. The timing was 'locked' at 19* with a laptop. I am putting my confidence in the ability of the young man that did this, as he was the one that installed the system and did the research/study of the system. I only know as much about the system as he explained to me, but I know he did not intentionally install any type of 'timing curve' into it. Are you still thinking 'detonation'..?




The only way to know for sure is to hook up a timing light. Here's how you do it. Its crude, but it works.

Pull the #1 coil pack out. Insert spark plug wires into the boots and the other end to the plugs.

Bring the #1 up to TDC on the compression stroke.

Use a piece of wire and bolt it to the front cover and use whatever bends it takes to get it over the damper.

Use a piece of masking tape on the damper and mark TDC under the wire. I like using a dwell dial timing light for this application. Fire it up and turn the dial on the timing light while at idle and rpm. You'll then personally know whether the timing was locked or not.

Was there an A/F gauge in the car?

Just for some more info, the #2 and #4 mains are the only mains cross drilled on this crank.




From what little info that is out there about the oiling systems in these engines, The good aftermarket cranks are not cross drilled at all. I have to wonder if the cross drilling is the reason for many of the oiling related failures

The oiling system issues doesn't put me off building one of these engine, my fiance and the two unfinished engines I have do

Not quite a year yet,,but, I have this POS SOB almost back together and ready for another test. COMPLETE new short block other than cam/lifters. Molnar crank/rods and Ross pistons. I am getting too old for this stress, head aches, heart aches, etc.

Minor details

this go-around works out better for you

New style motors + building more HP = sometimes s#*t happens

That has crossed my mind SEVERAL times in the past few months!! But, as a wise old(er) man once told me about motor building.."You are only as good as your last one." He was meaning, NOBODY remembers all the previous ones, just the one everybody is talking about at the present time. So, I HAVE to make this PITA a good one before I break camp.

Got to test this evening. Motor had been run at shop on gas till it used up 5 gallons. Switched over to alky for testing this evening. Put about 15 laps on it with 5200 RPM max. Checked everything over and started letting it eat alittle. Had rev limiter on 7000. Ran about 10 laps, checked everything over again. Track needed alittle watering, then put another 15 or so laps on it. All seems good right now. Driver was wanting to turn it up some more!! He was love'n it!! I will allow alitle more next run. It was picking the left front up at mid straight-away. Going to give it just a bit more fuel pressure...was a tad low at times. Hopefully, this thing is fixed with the new crank.

Sounds encouraging

Remind them that lapping the 2nd place car will lead to rule changes

Got the first race night on it. All went fine with the motor. LOTS of problems getting it hooked up. Burned up 2 new tires. All seems good with the motor,,,it's up to the chassis man and the driver now.

Remember, Karl Kinser had to detune Mark's Mopars because they made too much power. Much more than they were used to with the Chevy. Too much power is a good thing. Just get to work on those shocks, springs, and bars. The wheelman will figure it out.
