Nice!
Could use some tipside pics. Is the Trick Flow Track Heat intake from a 351C application? I wonder how big (width/height) the runners are nearer the plenum base.
L-o-n-g ago now here on Jay's site, before he started on the adaptor path, we had all discussed two other intake schemes: one was the two piece, bolt together single plane intakes (Chevy...but) that allow almost unlimited porting options, easy ones at that.

Have to admit I have not heard much about these intakes in some years now but it's a viable idea for the adaptor.
