390pi faster

Response to How do they compare? Long post.

I don't have the Gonkulator up right now but from past files:
The 390pi auto cars Gonkulate to about 310-320hp depending on the year, and run 15.70 at 86mph or so.

The Bird engine I would also GUESS at about 320hp, those valves seem really big though for a 390 with almost stock cam. Probably not helping much.

The Bird is usually 300 lb or more heavier than the Gal so I'd bet on it being a couple tenths and a couple MPH slower.
