Prior to last year
I ran a 421 SBC with dart 23 degree heads in S/G , 9.90 @ 148/150 MPH ,,, Motor in my Cutlass would run 8.70's @ 154 all out -----I put about 400 runs on a set of LA Enterprise / kryptonite 6" steel rods ,,, I would leave on the converter every pass ( 5800/5900 RPM ) and go through @ 7700/7800 ,,,, Never broke a rod !!!--- 3years ago I spun a bearing and switch to Comp Star steel rods and never had a problem ,,
sold motor last year and new owner hasn't had any problems ,,,,, I've ran just about all the rods over the years and the one caution is watch the weight specificly if you will be twisting this thing above 7500 ,,,
the Olivers , Carrilo's , Crowers , Lunati etc are all good but some are very Heavy !
