Olds 403 cam run in ready!
11.05:1 CR, iron #7 heads with mirror polished chambers, Exhaust runners and piston tops, running 10% xylene in premium gas, can't hear possible knocking due the noise with open headers. Revs get up and down quite fast, nice.





403 Olds Overview
This is a shot of the 403 Olds in my '84 Cutlass. Propelled me to many 11.50s time slips. Swapped the cam out to something more streetable for prospective buyers. $3500 with lots included. Less than 50 miles on the motor...under 100 passes.
