saw this truck in person yesterday. i can attest to how healthy it sounds. really bad ass! :)

got 100 psi compression on both rotors before startup. goopy apex seals and refurbed housings.

just did another engine with this refinishing job. this engine is my 3rd kid Sierra's series 5 turbo II. you could follow her build on our facebook page. search for ARP Shop.. front rotor was at 140psi and rear rotor was at 139-ish psi. this was on a cold crank and about 250 rpm cranking speed.
