New hammer what will it run?

Just curious what size of rear tire you’re running and what your chassis is certified for. What block is your 416 based on and re you running a girdle, four bolt caps, or block fill? I do like that Erson cam profile for everything that's planned. While you could make more power and run faster with a roller, it may not be worth it if you have to upgrade the block or chassis to handle the extra power or to pass tech for a different e.t. range. What you have is more than adequate for that 7000 rpm shift point, and running it on e85 will equate to about a 10-15% power gain, possibly more with the good heads and 12+:1 compression.

E85 is no way a 10-15% power gain. Your talking 50+ horse gain.
Most guys i know who run it with a carb may or may not pick up a few hundreds, not much more, if even that.
Car will run cooler, and its cheaper more consistent than gas usually are the real bennies
