I cant tell you specifically, but its probably a slightly later model smog motor. The most important aspect of big blocks is the heads. Large oval is the way to go unless you go aftermarket ( I beleive thats 1970-70 1/2 truck heads)

My guess is he read it wrong and it is 3999290. Those casting numbers are tricky to read sometimes. This would make it 68-72 truck 396 or 402, and 70-72 chevelle, camaro, nova block.

Well I thought so too until he posted a picture of these numbers.

Oh well.

Thanks for your input guys.
