Quote: The way I see it is if Dave was so smart he should have said bush the lifter bores to start with,since the cam is cutting edge and pushing the bounderies.
The lifter bores on the big block Mopar don't need bushing in most circumstances. I hear the small blocks have a lot more alignment issues and need bushing more often.
My block had a NF904 Ultradyne cam and now a Scott Brown cam with an agressive intake lobe. No problems at all, not bushed. So even if he said to bush it, that would be CYA in my opinion. The oversize lifter bores is another issue. If it is off, it needs to be bushed, if not, it doesn't!
