Anyway, through our friends at GM Performance Parts, we got in touch with Mike Morgan, the parts manager at Lattof Chevrolet in Arlington Heights, IL. (800-441-5150, www.crateenginedepot.com), and got the correct timing set for our motor. Finally got to installit this morning, and everything fit like a glove! Once the motor's buttoned up I'm gonna write an overall story about the build/assembly right here on the Super Chevy website, so stay tuned!
