After mulling it over for a long while, i finally decided to send my already machined block into a very reputable shop to have my lifter bores bushed. I am running a solid roller cam that i purchased from Duane Porter as he picked it out to go with my combo and indy heads that he did.
Problem is that i just saw in the mopar engine bible (mp b and rb engines) that they say to never bush the 2 lifter bores for the #2 cylinder because they claim it will significantly reduce oil supply to the mains and cam journals.
I have been doing a decent amount of homework on this and never saw this mentioned anywhere else. Is this true? Or has this been disproven? Otherwise i need to call the machine shop up asap and advise.
By the way, this is a 71 400 block
