Any benefit with the 351 block over say a foxbody mustang? Seems that getting a 5 speed for the mustang would be easier then for the 351
In stock form, more torque. Both are the same block, with the exception of the 351M so you can use any transmission for a Windsor small block auto/manual. OEM parts interchangeable(heads, exhaust,intake mani etc). Aftermarket support is vast so mods are cheap.
