Here I go again!!!
I've mouthed off about my old junk 301 so much that everybody is probably getting sick of hearing about it but I'm here to tell you straight out the sucker flat got up amoungst them upstairs and just like the Energizer Bunny, kept right on a going and a going!!!
Sure I had trouble keeping a balancer on it at rpm'd b/c it wasn't balanced, but what the hey, I figure I had all of $150/175? in the junk parts sucker!!!
I retired her b/c I ate a stock rocker, bent a p/r and throwed a lifter and knowing now what I know, I shoulda put a new lifter, a junk rocker and used p/r in her and still kept beating on her instead of dropping the .060" over 409 "W" motor in her!!
Go ahead and spend your money AND I will bet a 6-pack of your favorite "barley-pop" that you won't beat on your original rebuilt Z- motor as bad as I beat on my junk 301 even with all the money you put into it!!!
