Bill,
For standard or street port that's OK, but for a PP or larger sized side ports on a 13B - 200hp  would be very ordinary at 7,000 rpm.
For a 12A it's pretty good, a 12A PP would be better.
Knowing Lynn's background I figured it would have to be a 12A.
I wonder if they ever PP the old 10A and what they got out of them?
An all Al - PP 10A would be perfect for my install.

George,

What have you been looking at?  That is a pretty hot rod engine for a 13B.  It is making 200HP at only 7K.

We are not going to be making the kinds of HP we are talking about here on the list because we are not geared and propped to get the rpms necessary to make it possible.

Lynn,

What inlet configuration was that rotary on that dyno. It seems lower on power than expected for a 13B, so must be a 12A.

Same thing. Second picture
