Not to draw away from original poster's intentions, but... what I'd like to see is comparisons between Eddy vs Trick Flow. I'm building a 410 with CR about 9.5-10 (Hughes kit, engine partially built)... camshaft (flat hyd) still to be determined ...wanting wide range rpms especially strong mid-range and ability to run strong higher rpms (I do pylon AX, HSAX and road course lapping sessions).

My purchase is on-hold until ~mid-summer or end of this summer, maybe into early 2020... maybe the EDDYs are simply established and proven.
