new 360

That makes sense, rumblefish. I found a good one not far from me. I also found outthat the shallow dish pistons are for the larger chambers, and as the years have gone by, when the chambers get smaller, the dish gets bigger. So, I can raise my compression by finding some 68cc heads, by my math that would give me a 9.2:1. then I don't have to mill them any more than to make 'em straight. And I can still use stock pushrods. I hope. But I will check! I heard that la rockers are the same as 440 rockers but w/out the spacers. Is that true? Cause I can get crane 440 rollers on craigsllist cheap right now, just thought I'd check it out! Oh, yeah, I got the code off the block, it is 4006830-360-5. Can anyone interpret this for me? Thanks!!
