Lynn,

   Did you mean "scrape the indium off the first 1/8 inch of the rear of the rear stationary

gear main bearing" ?? 

   

The non flywheel end of the rear main bearing. The gear end.

 

The first missed shift will get you a shined up bearing in that area. If you are unluckey, the bearing will try to weld to the crank. If it ain't there it cannot weld. The Aussies turn them up over 12,000 RPM but they use a 2 piece crank and install a center main bearing to control crank flex. No crank flex=no bearing problem. But a rev limiter in the MSDs with a 9,600 RPM chip will work fine.

Use chips in both MSDs. The trailing will take it over the red line as well.

 

Sign on to "nopistons"  http://www.nopistons.com/forums/index.phpand read FAQ about porting. Most of the nopistons people are drifters and street racers, with little real engine experience. But many build huge engines and just meet at dyno shops and race them on the chassis dyno.

 

Go to Paul Yaws site www.yawpower.com and memorize the tech section. Geat pictures too. I have met him and watched his engines perform. One of the best builders.
