Shaver is starting out with a nondescript '90s-era Chevy block. It's a two-bolt main unit with GM Performance Parts billet main caps on ARP studs. This foundation is plenty strong enough to support the power Shaver plans to deliver on dyno day. He says "I don't see anyone making the 600-plus horsepower numbers I've read about in other Engine Masters buildups. It's just not gonna happen. If someone touches on 600 at peak, that'd be amazing. I'm hoping to pull down 500-510 lb-ft."
