Ron,

Note post #7 same comment...this engine I believe was built by Rippie as was the stand alone ECM.....Rippie had a dry sump setup on some of his LT-5 race car and that makes sense that this does not either.

The LT-5 inability to run over 8K was related to oiling on the lower end....when the car would hit 8K, pressure was pushing the oil to the top 1/2 of the motor, resulting in failure...the weakness was not a chain issue. I tried calling these folks awhile back and no one picked up....also tried conecting with them on FB.
