I finally discovered why I am not getting oil up the pushrods--- there is an obvious amount of slop around the lifters and oil gushes up around them. I removed several of the lifters and discovered that the lifter bores are about .003inch bigger than the lifters. The lifter bores are not out of round and appear to have a honed finish. The engine has only about 3500 miles since the last rebuild. The question I have is----do they make an oversize roller lifter? If not I assume that I am down to finding a different block, what a PITA. /forums/images/graemlins/confused.gif The motor is a newer style 350 that is bored and stroked to a 383 and has a roller cam. Any input is appreciated!
