Verrry nice work,Steff! I hope it makes well over 600 hp! Jerry is a hell of a nice guy..I bought my SD Concepts aluminum main caps from him.Beautifully machined,and sized! Might have been an over-kill for my motor..but,I'll sleep better at night,knowing my bottom end is virtually bullet-proof..or close to it! Keep up the good work..hope to see the Runner soon!
