I say you’re better off with what you have. You may have some limitations on desired bearings, but it’s not like you can’t get good bearings that will work. It is desirable to have a smaller diameter bearing for high rpm use. You can have a wider variety of choices of crankshafts. Any rb main can be turned down to “fresh” b diameter. You also have the assurance that you have thicker bulkheads and caps. Finally, if it were to come to an instance of damage to your mains (spun bearing etc...) you could go to the rb size to save the block. I would say you have the best options with what you have now.

I figured it could be done with the right tooling and knowledge. I'm hoping I don't need to change the crank, but trying to think ahead if I do. I should have never went with Low deck mains!!
Thanks for the help. There is another option. Call Crower, Callies, Winberg, get thier opinion on the strength of a superior crank with small mains. Depending on your goals, options available might be worth some power. I notice that engines like the new Ford Coyote and some LS (?) motors with aluminum blocks come with center wieghted cranks. Might be worth some power in an aluminum block. Also knife edging, etc.

call Ohio Crankshaft and ask for Chip. Tell him what you want. They have cranks in stock both 4.150 and 4.250 that will take alot of horsepower. 440 mains and they have King bearings.. Birdtracker I saw they have billet blown alcohol cranks listed on their website. Also said they will cut to spec. Pretty reasonable price too. I'll give them a call if I need to replace this crank. Thanks! Only bearing in the motor that is junk is #4 main bearing. That journal has about 0.0008" T.I.R. when I spin the crank in the block.

they do everything in house. They line bore also! By going to the 440 mains the bearing selection is alot more. Birdtracker Very good! I had Ohio fix a couple Chebby cranks in the past and was very happy with the way they came out. I've been talking to Weston Machine in NJ about bushing the lifter bores for me and I figure they can do the mains while it's there.

Ohio crank fixed the thrust surface on mine for $200, their crank too. Quick turn around too
