Comments: Fresh motor with 2000 miles. Nice lumpy idle and very drivable. Smooth off-idle transition, even with 3.55’s. Pulls 12-13” vacuum at 800 RPM. The motor is just as happy at 1500 RPM as it is at 6000+. 12-13MPG, but I didn't build it for fuel milage. Can’t wait to get this thing to the track, hope to go low 13’s at least.
