good morning boys,when the car was from me I repair the 124 engine and drive it like this.The 124 have lot of torque.You can always look for a 1000cc engine but its not the same.Also a PBS have a value.For the records there where OT engine with filter "lump " and whitout on the end.I recive one original OT spider from USA like this and find in the records that it was correct
