Nice build!

Do you think the factory 2x4 and carbs would yield more power?

That's a bit better than the Ford advertised 425hp  ;D

We have a dyno sheet on a high riser that was intended as a 100% stock rebuild, made 530hp with the 2x4 intake.

Absolutely.   

Or Jay's intake adapter with a big fat single plane.

Which cam Brunson?

I'll look for you this weekend. If I remember right it was a comp custom grind trying to mimick the factory cam. Not quite an exact match but close.
