hi, jus a quick question, the std style cosworth main bearings - 1 shell has a oil grove in it and the cap shell is plain, i am planning to use what i think are called std pinto style bearings where both the block shell and the cap shell have the oil grove in them, i am using a graham goode uprated oil pump, will this cause oil pressure problems? i have spoke to alot of people about this and they have said as long as the bearing to journal clearences are right it shouldnt give a problem, if anything it will feed more oil to the bigend bearings?
