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.
