<<The feature mentioned that the 3B motor was chosen for it's
bottom end being more stout than the 7A as it was designed to
see boost.>>


Not rocket science there, the 7A is 10.3:1, part strength aside, something
will have to change there.  Other than that, both 3B and 7A have basically
the same internals, the 3B using forged pistons instead of cast though.

With that compression???

Its a real 3B motor, no 7A parts...

Yes, it makes about 7 more hp, and strengthen's the entire block due to its
increased thickness...no, I'm kidding, they think it looks better, dat's all.

No cost was spared on that car, no reason to compromise by using inferior 7A
parts.

right...like I said above, its for looks.

Yup, that's him.  Nice guy, really clean car.
