Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION

I have a build planned this winter for my autocross/roadrace themed , D150 Shorty. Currently building a 371 inch, 11.0 comp, Eagle steel crank, Scat I-beam rods, Icon Flat-tops ,BigMouth RPM's, SuperVic intake, and solid flat tappet cam. I don't trust solid rollers in an engine that I plan to put thousands of km's on per season-hence the solid flat tappet. As a sole result of this thread I have had an idea: In 2015 I ordered a pretty aggressive flat tappet cam from Comp for EMC 2015 use--It featured lobes that I don't fully remember now but it was something like 251/255@ .050" on a 104 LSA .600" with a 1.6 rocker , fully nitrided. Now because I have that cam already and will likely never use it or sell it --why don't I at least try it? Here is what I propose if anyone really cares- Since I know I would hate that cam the way I intend to use my vehicle, I will get a custom cam ground on the exact same lobes except I will specify a much wider LSA , something like a 113-115. Testing would be cranking comp, full dyno testing, and idle vac @ a common RPM. I should also state that I want and fully intend for this engine to be a 7000+rpm piece, preferably with a peak HP @ 6900-7000 and power that hangs on 'till 7400-7500 rpm.

This is the rotating assembly to be used in a different 360 block with the only difference being lifter bore bushings for better oil control.J.Rob 360 Street/Strip Bruiser-Dyno results
