Oldsmobile 455 data

Introduction

The Oldsmobile 455 engine was built in the USA between 1968 to 1976, and produced power outputs between 210 to 400 BHP and was used in everything from Saloon Cars to Muscle cars. The 455 is known as a very forgiving and long-lasting engine, not to mention being powerful. Spare parts are still readily available for this engine, especially in the States. There are a number of companies in the UK who can supply parts off the shelf.

Sources of Information

• A simple web search can provide lots of useful information. Some good sites are: [1] and [2]
• The Haynes Manual, Number 19025 "Buick, Olds, Pontiac Full Sized RWD models from 1970 to 1990" covers this engine. The club has a copy - should be on the bookshelf in the clubhouse.
• Ultimate American V-eight engine data book, 1949-1974, Books 1949-1974 By Peter C. Sessler. Available new and used on Amazon, but the text appears FOC in full online here on google books! Has information about all American V8 engines, a bit of background, etc, but - most usefully - how to identify and date an engine. Has block, head and manifold castings number information - an invaluable book when buying a replacement V8 engine. Also gives power and torque output data.

Spare parts

• Oil filters are available from local parts factors (e.g Motorists Discount Centre, Newbury 01635 42015) But don't confuse the people by asking for a filter for an Olds 455 - simply ask for the filter by part number: Fram (the manufacturer's name) PH25 (the part number) or alternative, Fram PH3429. (Other info I have suggests the following makes/model numbers of filters will work: AC PF45, Motorcraft FL-331, Purolator L20123)
• I have ordered parts from USautomotive (01234 273155). They're very helpful and have the parts in stock, or can get them quickly.
