Does any one know how to tell if a '71 Ford 429 is internaly or externaly ballanced. It has a sleeve behind the balancer. Was purchased as a short block with no flexplate.

The 68/78 429/460 is internally balanced. The 79/97 Light Truck 460 is externally balanced.

An external balance mass (the spacer sleeve you are describing) is behind the neutral balance damper.

off topic but i was wondering if any of you could hel me to identify what it supposed ot be an old 429 in a 69 fairlane my stepdad bought it runs good and the car was 4 linked with a 9" rear and bars and tubbed out and entire rear floors removed and such, stock car otherwise but rusted junk now from sitting

how could i ID it if its a 429, something that only a 429 would have ?

so a 460 is virtually the same as the 429 ?

im not much a ford person, i learned alot about ford v-8 engines when i replaced the crank bearings in the bottom of a 351 C in the 77 pickup last fall for him after he had it turned for new ones, it runs like new and has been great ever since

thanks for anything

Ford Classics has a description of the "385 - series" engine family which includes the 429 and 460. This engine family is also often referred to as the "Lima" engine, as it was mfr'd in Ford's Lima, Ohio engine plant.

Other characteristics not mentioned there are:
7-bolt valve covers
Canted Valves
Fuel Pump bolts are horizontal

More info including some casting numbers and where to find them.
