Good lord lol i barely run my 340 past 5,000 rpms lol thats some confidence there
That thing sounds sweet for sure
Since we are guessing i would guess 6500-7000rpm max,its singing some nice tunes but dont think its on the other side of 7000rpm.
It's a X block W2 head 349 cube mill in a 4500# truck. Sweet music.
