Splayed main caps on a 360?

I figured the added weight and pistion speed should not be an issue as im running a roots blower so no need for high RPMs.

I think the stroker on 7 psi should be a street stomping machine and enough to get me down the track at a good clip.

My car is FULLY gutted, all aluminum interior, custom 9", spool, 35 spline chrome molly axles, 12 point cage, frame connectors 29x10.5 DOT drag radials and all the good stuff...
