It is the correct 455 block. The motor and transmission have been modified somewhat but are the correct combination that it came with when new. This W-30 has been in our museum for many years and has a very interesting history!
From our museum collection is this 1970 Oldsmobile 442 W-30 Sports Coupe!!
It ran it’s best time of 10.90 at 125 MPH there and was retired after the 1985 season. It has been restored back to it’s original condition but still sports most of it’s original interior.
