Mile High Perf Dyno Tune 340

Love this thread, thank you. I'm at 6250 ft. with a similar combo but a 360 in a duster. Ported X heads, 3.55s, LD340 intake which is similar to your eddy rpm,headers/H duels, 284/.528, but 11:1 comp and a 750. I say increase compression. I ran 14.7 at 96 and after 5500 rpm it gets a little flat.
