Mixing bearings for clearance

[Rich Biebel]

Scat parts are somewhat questionable.....probably made in China...
Rods maybe can take it...bolts sound like they failed.
Possibly you can find a better rod that you can send to NHRA for aprroval...and make sure to use good bolts no matter what rods you use.

You can't make an engine go to an rpm that it is not going to survive at and if your driver insists on trying to go to a higher rpm than is safe......there must be a rev limiter capability in your ignition......I would suggest that you use it and especially on a burnout.....It is very easy to let the rpm get away from you. I use one in my dragster......I did not use one in any of my doorcars but I have made a lot of runs and always control that rpm during a burnout......There is really no need to do a burnout more than about 500 rpm above your converters flash rpm......so 6000 or maybe a bit more is gonna be plenty........8000 is reserved for Competition Eliminator entrants......LOL
