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.





Olds 403 firing
"79 trans am with built Olds 403. Still haven't had the timing light on in it and the carb jetting is completely off being that I bought it used off of eBay, but hey it got it to run. Hasn't been on Dyno yet but guessing 550hp when tuned.
