We are trying to put a motor together however our rules say we must remain stock. we have a 2001 chevy cavalier with the stock 2200 motor and have quickly came to realize (after two races) we need more motor. we don't want to really break the rules just push them to the limits. does anyone have any input on what parts to use from different years to build a the best motor possible? ive herd of people running he 97 heads on the 98+ blocks and it raises the compression to 13:1. I will use the search button I was just wondering if anyone wanted to put their input on here too. thanks.
