The V8 used in all capacity Ford CMP's was 239 Cubic inches, or a stroke of 3 3/4" and a bore of 3 3/16". They were nominally rated at 95hp. All Australian (and NZ) built "Bren" Carriers also had this same engine. Ford commercial trucks and cars up to the end of the war had 221 cubic inch engines (3 3/4" X 3 1/16) of 85hp.

Howard, just to clarify what you said. The Ford V8 was the first available to the ordinary motorist in an affordable production car. There had been many makes prior with V8s, but they tended to be expensive luxury makes with limited markets, Cadillacs and the like. There had even been French Renault V8s used in WW1 to power fighter planes.

BUT! The Ford was the world's first V8 with a one piece block, the secret to it's affordablity. Took Caddilac 10 years to catch up and Chev more than 20.

Tony, My engine (which I believe to be the original) is/was a chrome sleeve bore 3 1/16". I always thought the 3 3/16 bore became available in '42?? Isn't the 3 3/16 what the old timers refer to as the "Mercury Engine"?
I await your
Thanks M8

Howard,
Check out this link. Although my Canadian friends disparage the fact that these are US-made engines, I doubt if there was much difference if any. Something in the vein of reinventing the wheel..... http://www.vanpeltsales.com/FH_web/f...ifications.htm

The 3 3/16 bore is a Mercury engine, being released in 1939 as the 99A (or the Canadian version C99A). It is the engine size used exclusively in Ford CMPs from the prototype. There have been variations; the C29A in 42, the C39A in 43, and some F15As had US-built 99TF Mercury truck engines but they have all been 239ci.

In 1942, the Ford 221 (3 1/16 bore) updated the main and rod bearing sizes to be the same as the 99A/29A Mercury, but remained 221ci until the "1946" models were released for the civvy market in late 45.

If your engine has a blitz engine number (like 2G1234F, etc), then it has been resleeved down to 3 1/16 for some obscure reason, like road tax, motorsport or availability of pistons! If it has no engine number on the block (remember 'Ol Henry put the number on the gearbox bellhousing!), then your engine is likely a replacement from a Commercial truck or a car.

And the Canadian sourced F15s we see here in Aust.
