The Mustang Is actually my brother Georges'. We are thinking about a big block clone but if the shock towers are different we plan to keep it a smallblock.

Boss 429s use unique shock towers. All other big block mustangs for 69 resemble small block cars. Big blocks have some extra reinforcing at the upper control arm mounts. A big block clone would not be turned away because it lacked the reinforcing. It is almost unnoticable.
Build the BIG BLOCK, we need more FORDs.
