I don't know Dave most people don't pick up on the height and width difference between a 289/302 and 351W. Dressed properly a 351 can be passed off as a 302 to most people.

This is a picture of my 77 Mustang II engine compartment (as you can see, I'm still a couple of hours away from firing it). What you don't see beneath the blue paint and stock valve covers is a balanced .040 over 351W with Edelbrock Performer RPM heads, Performer Manifold (somehow the name got ground off) , cam etc etc. The exhaust manifolds apperar stock, but have been ported and flow into a custom 2 1/4 in headpipe and from there into a 2 1/2" exhaust. Most people will never look beyond the 302 decal on the aircleaner.
