Thread: .003" Main Clearance for Street?!

Tweet

well this happens you can go to 001 and get were you want 003 is big for a sbc street engine you can get a P bearing for 001 and that is what i would do on mild build .the race stuff i would not worry much at 003 and you can buy a set of 001 h and split the run the 001 on the main cap that with get you 002.5 but i only run the H bearing s on the street if that the only thing that fits the crank radius and when i do the bottom end i set all housing bore and the small end hi crush there is a 0005 right there that will change or bearing size you will see lower oil presure if the rods are out there as well ? but it will not blow up from it you may have low oil psi warm at idle

i have 003 on my race only motor haha. i think 3 is a bit much for the street, because of it being so big on clearance i run straight 50wt oil.
