HI FZABSKI. I have a 10-10 428 crank in my motor,eagle rods,araias pistons, ATI dampener,and 30 lbs flywheel. 100 psi
oil spring in a high volume pump. I had everything balanced together and spin my motor to 6500 rpm with no problem. The crank has been cross drill to help the oiling problem of FE rod bearings. If you donot beat the car hard all the time, what you have is OK. If you get the power bug, you should go with the forged crank,steel rods with the chevy rod bearing and not worry. I am guessing that the kit is about 3500.00$ with all the balancing and machine work done. Next year I am going to a 484 crank kit and 10.0 compression. A bigger blower cam and roller lifters also. I am hooked on power. I have to beat a dragon next year at the Run&Gun in street class. Good Luck ps spending more money now on stronger parts will save you down the road. Remember that is part of the family and work in progress.
