Picked up a rough "project car" a few weeks ago. Its a 1970 coupe. Appears to be a 350 350 hp car but Im leary about the originality of the motor. The car was built in late April but the date codes on all the motor parts, block, heads, etc. is January 1970.
Is it pheasable that a motor built in Jan. 1970 wouldnt find its way into a car until late April 1970? If not whats about the greatest time difference between a motor build date and car build date you should accept when looking at these cars?

Usually not.

The NCRS will allow up to six months between engine assembly date and vehicle time/build date. In most cases, the actual time frame is much shorter -- usually no more than a couple of weeks. The engine in my '68 was assembled on April 9, 1968. The time/build date on the car is April 20.
Check the pad on the block at the front of the right head. You will find two numbers stamped there. One will be the engine code and will identify when and where the engine was assembled and it's suffix code. The second stamp will be a derivitive of the VIN of the vehicle the engine was originally installed in.
Hi LH,
I'll agree with Mike. That amount of time while not the norm would be feasible.
I believe 70 production didn't begin until January, so I guess there could be some oddities.

1970 was an odd year with a big strike. If there are any years in the C3 that will have skips in dates from production to assembly, it will be this one.
There's lots of weird and wonderful date combinations out there. A January engine in an April car wouldn't get me worried. Got a photo of the stamp pad?
