Let's Build a 416 with Cast Iron Heads and Manifolds

I built a 511 low deck FAST combo for a customer.
12:1, ported 906’s, solid roller.
Went a best of 11.58@3650lbs on bias ply red stripes.

This was a very basic build, with no real “trickery”.

It didn’t quite make 530hp on the dyno with ex manifolds.

Conversely, I dyno tested one that had lots of fancy parts in it, more CR, noticeably better heads, a much better intake manifold, and way more valve lift........and it made quite a bit more power than the one I put together.

The owner of that car stopped running in FAST before really getting the car sorted out well enough to make good use of the extra power.
