351c main girdles

panteradougMember

I need to ask my engine builder what he thinks but have any of you used a main girdle to increase the high rpm durability of the stock block or is it a waist of time?

Also any of you who purchased Buttmores new blocks, is the oiling system stock Cleveland? Do you still need to sleeve the lifter bores to restrict top end oiling?

I'm considering buying the aluminum block. I would suppose that it is still too soon for anyone to have raced it in the 8500rpm area?
