Has anyone ever done this? Just kinda looked the crank journals over and throw in standard sized bearings. I hear the bottom end of BBO are among the strongest ever made in stock form. So I was wondering if this has been done by any other 455 olds owner. Ive had my Dad and a couple of uncles who are all pretty good mechanics say they have done this just to refreshin a block and raise the oil pressure and never have a problem. Ive drove a couple of the rigs theyve done it to without knowing and never noticed the difference.One was a Pontiac 455 and the other was a 454. I am just planning on this 1st stage of the motor to be a new edelbrock performer intake with a 750 carb and the stock cam. Just figured Id ask because money is rather tight and if I cant get the car going soon Ill have to sell it and give another olds guy a chance at building a Cutlass with a BBO. Thanks guys.
