I figure they got ta be better than stock for an Olds 455. It's about the same $ as reconing the stock ones. Yepperdooo I'll be giving the evil eye >:D On ALL the Dimensions!. The motor will not see above 5500rpm ...unless I air it out. A rev limiter might be a good idea. I'll have ta check the msd 7al .
My msd 10 has it but it's in a buddies racer.

When i bought my CAT rods i asked every ones opinion on it.. The ones that never used them didnt like em, and the ones that did were happy with them... I forget his name but on HB he told me he has 75 passes on them @7500rpm's with no problems. And they are NHRA approved or some shit like that i forget........... dont mean shit in a boat tho ;D 4340 and arp bolts hell ya i would do it................
I am buying a set of them for my next build ;D for next summer........

I have never used cat parts but I don't think its the material people typically complain about on CAT products, it the machining and tollerances that come in to question. But there again I've heared ppl complain about eagle and run out on their crankshafts.

Josh is correct. It is the final machining that we are all after for a quality product. 99% of the stuff we buy is overseas forgings and some companies have way better tolerances and Quality Control than others. Some will say Scat sucks some will say Eagle sucks etc. When I get stuff in it goes right to the machine shop or someone who can measure everything out so I know id I have to send it back or not for a replacement.
-
I own a machine shop, thankfully. ;D I always double check stuff, even from a reputable shop.
I can post my results ( tolerance wise ) if people are interested.

Absolutely interested in what you end up doing/how it all turns out...
