Two of the first cars ran at the POC Tribute event. They were turning in sub 2min laps at CA speedway. Depending on how things shake out I might end up having one built. The crate engines are about $7500 and the spec is a stock engine. Pretty cheap if you happen to blow one up. Cost to mod a stock car is about $15K plus or minus.
