I’m running 4.75 Callis crank with Oliver rods. Indy Max aluminum block, cnc Indy SR heads, 11:1 compression. It went 10.15@133 in 100 degree Arizona heat the first pass on the new engine and suspension on 91 octane and very conservative timing. Waiting for the Indian tribe that owns the land the track is on to lift the COVID mask mandate to go back. We’re already 100+, probably wait until the fall.
