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.
