The Vo is the plant that built the engine 720 is the month and day and the zzz is the engine code or parts make up for the engine. Now with that being said the engine was built at Flint V/8 engine in Flint, Mi. on July 20 year is not shown. I can also tell you the zzz engine is hand built off line on a special operation. Most of the hot rods like this engine because of the horse power it puts out. I know this as I was the General Supervisor for the job that built these engine and retired with 37 service. Hope this helps.

Vehicle Identification Number (VIN) stamped on metal plate located on left side of dash panel. The VIN is also stamped into passenger side of engine compartment bulkhead or driver's side of dash panel, visible from outside of windshield.

Engine block stamped number location

its by the motor mount bracket area.. on the block.. its really hard to see. so you need to clean it off really really good.. and don't use a wire brush for they are not stamped in the deep.. they are barely their... should be a flat spot in front of the mount on the block.. get plenty of light and a some really good glasses to see it.. it looks like they used a engraving tool on it.. not a stamp like we are use too .. just be careful cleaning it.. NO WIRE BRUSH... IF SO VERY VERY LIGHTLY..

Cant find engine number on 2001 v8 jeep grand cherokee

On V-8 engines, the serial number is stamped on a machined pad on the left front corner of the cylinder block.

On the six cylinder engine, build date information can be found stamped on a machined pad located on the right side of the cylinder block between the No. 2 and 3 cylinders.

I hav a 65 f100,motor has been swaped out,i think its a 302,the onley block numbers i c r on the front block pansenger side that reads 2(over)80

There should be a serial number stamped on the block itself in front of the one of the heads (the one that sits back further. With this serial number you should be able to contact a dealer and find out the correct engine size. Older Fords had either a 289 cubic inch, a 302 and a 351 small block which from the outside will all look the same.
