Help Identify This 340

Aug 1 69 would be first day of 70 model year. I would assume an early 70 340 engine. This should be a good 340 builder to go after.
high compression, internally balanced, steel crank. early 340 X-head w/2.02 intake valve.

FW340Pxxxxxxxx - would not be an E being that it would have been cast AFTER the 69 model year began.
