Hello, New guy around here I want to rebuild my engine 292 yblock . I can not afford all the parts and machine work at the same time . Can I take the engine apart bring the block to the shop and if the shop says that the block needs to go .30 over can I have the work done then down the road buy the pistons and rings or does the shop like to have the pistons . Will .30 over rings need to have end gap checked or is .30 over .30 over. Please excuse my ignorance thanks
