I think that one of the 4 cylinders like out of the mid 70s pintos? would be ok but all the accessories and reliability on the road would be over the hill---a LS 1 that is picked out of a late model vehicle that has all the accessoies ( 12volt, a/c, power steering, water pump) mounted high up ( like on suv or pickups) along with trans, wiring , fuel pump would give reliability, economy milage and outstanding performance-------plus get it in aluminum----------lighter weight on the front for weight distribution for handling and braking
