I just had a 1974 360 completely rebuilt for my convertible along with new pistons with stock compression,3 angle valve job on the heads, '68 340 intake, Edelbrock 650, TTI headers, a nice adjustable valvetrain and the Hughes Whiplash 360 cam.
I haven't heard it run but my guys told me it sounds healthy on the break in stand. Should be in the car later this month!
I will let you know how it runs and post a video.
