The full size Oldsmobile 88 was launched in 1949 and by 1950 it had become the General Motors brands best seller a position it maintained until 1974.

In 1971 all General Motors full size, B-body, cars were restyled and enlarged while maintaining the same 124 inch wheel base as the previous models first seen in 1969.

The seventh generation Eighty Eight launched in 1971 was available with five different body styles including a convertible and the first 88 station wagon since 1964 and with three different trim levels.

Only two engine options were offered with the seventh generation Eighty Eights either 155hp 350 cui / 5.7 litre like the 1972 Delta 88 Royale Holiday Coupé seen in these photographs or 250hp 455 cui 7.5 litre V8.

All seventh generation 88’s appear to have been fitted with the same 3-speed TH400 automatic transmissions.

Delta was the name given to an upmarket trim on the 1965 sixth generation Eighty Eights.

By 1972 the Delta 88 had become the base trim level for the 88 model and as can be seen on the boot / trunk lid this example is the top of the range Delta 88 Royale.

For 1972 the 1971 only Flo-Through ventilation system had been completely revised to use vents in the doorjambs rather than the earlier systems trunk lid vents which proved most unsatisfactory with customers.

Thanks for joining me on this “Doorjamb Vented” edition of “Gettin’ a li’l psycho on tyres”, I hope you will join me again tomorrow when I’ll be looking at the last in the present series of jet cars. Don’t forget to come back now !
