well guys...3 to 4 gallons in and this thing is toast...the quality just isnt there...rear bearing gave out and ruined the rod..sad becuase the motor was running ok and still had great comp but between the junky bearings, ramp in the crank that gives and smokin temps to get any type of performace this motor just doesnt cut it...i am a firm believer that temps that high ruin motors and bearings and thats why these things give so much...a local sponsored Team A driver here ran them and had 4 diff motors give from bearings and rod failures after about 3 gallons on all of them...
