7000 RPM small block
Should have forged pistons, better crank and at minimum rods with arp bolts and reworked. But is cheaper to get better rods.
Why not build the 360 with enough torque to live below say 6200rpms?
I had a 273 that lived in the 8000 rpm range, but it had to so it could make the power I needed, but you have the cubes for more torque.
