I questioned that as my Grand National only had 3 plug wires per cylinder bank:-)
Is it really a new style Chevy?
Thanks guys!

It appears to me to be a new generation big Block GM engine w/ a turbo charged induction system. The fender wells also appear to be from an older vehicle style. This could make a good " Guess what this is".
