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

The Hensley 416 that I'm duplicating because of a cracked block had W2 cast iron heads, it was in a 2800lbs car and went 9.40s. My car is 2500lbs with a 408 in it now, hopefully when the 416 goes in it will be in the 9.20 to 9.30 range. The dyno sheets of the original engine showed 623hp @ 6400, so I probably won't twist it higher that 6800.
