Uncle David rebuilding my 403
At my Uncles machine shop looking at my nearly complete Oldsmobile 403 for
my 1979 Trans Am around 300 hp, used 71 Oldsmobile 350 heads.
1979 Trans Am fun with the rebuilt motor :)
403 olds motor, big block chevy performance valve springs, straight headers
and a big cam. Lift: Intake 475 Exhaust 500, Duration 215/225, and 1971 Olds 350
closed chamber heads machined and port and polished, Edelbrock intake.
403 Powered Olds 442.avi
Quick video of my Olds 442 after installing #5 heads and bumping the
compression ratio up a bit. Motor is a 77' olds 403. The car won't hook
up with the street radials and smokes em though 2nd gear.
