No issue at all by snipping a little off the AA mount. They are very beefy, Others have done this, and have no issues. You will also likely have to widen one or two of the holes for your side to side placement of the motor.
All that being said.... If I could do it again, I would try to use the clamshell (old sbc) mounts with a 4 bolt adapter plate. Most adapter plates allow fore/aft movement which is awesome for clearance on the manifolds. My buddy Matt (clonestocker on here) did this on the cheap and It came out way better than anything else I've seen anyone do on here.
The corvette manifolds are trick huh? Get the aluminum heat sheild though... oh an I would coat them in high temp paint if I could do it again.
You are on track. Take your time and think everything through... do everything as best you can, and buy only quality parts.... in the end you will thank yourself. The cut corners is where problems show up (mine: transfer case - should have rebuilt it - bang head).
Have you decided on fuel delivery?
