=====================There are numbers on everything ...carbs on 427's were different then
on small blocks and varried with the Hp output...The distributers also
were different... if every number checks out Block,Heads, Carb,
Distributer etc to a 400 HP 427 you can be reasonabily assured that is
what you have if everythin g works our to a 435 Hp 427 then that is
what you have...no way to tell if it is the OEM engine however.
