how to identify 351w as opposed to a 302 or 289?

Very very simple to tell a 302 from a 351.
just look at at the top assessory hole on the FRONT off the block where the heads bolt to. The top hole on a 302 is about 1/2 inch from the top of the deck and a 351 is about 1 inch from top of deck. Done, anymore questions.

Hey 2cents from a nickel, what a surpirse.

i could give you the whole nickel but i'd need a LOT more room and you'd still owe me change

This is a 351W, the increased deck height is most visile around the distributor.
