i need help i cant find any number on the block, cylinder head nrD2TEAA intake nrD3TE9425A2A what sise on the engine
There isno number on the block that defines the size of the engine, or what it's from.
Block and etc casting numbers cannot be cross referenced to Ford part numbers.
1965/67 F100/350: The only available V8 was the 352 2V, but the numbers you listed pertain to 1972/76 F100/350 360/390 engines.
1968/76 360/390 engines share the same engine block (and heads), only the stroke is different.
Measure the stroke to define the engine size: 352/360 = 3.50" / 390 = 3.78"
The D2TE-AA heads were introduced in 1972, used on F100/350 360/390's (without a smog pump) thru 1976 and have hardened valve seats.
The D3TE-A2A intake manifold was used on 1973/76 F100/350 360/390's. So, it's possible the engine has been swapped. 352/360/390 engines look identical.
Post the Warranty plate information and the VIN. If the engine has not been changed, the information can be found from that. Welcome to the FTE, post some pictures of what you have, including under the hood.
