Can anyone help with identifying the engine code on my Fender Tag
1963 Dodge Polara - manufactured in Los Angles
My White book does not give an ID for LA produced cars

Other plants would indicate a 383, 4-bbl??

I have a stroker Max Wedge engine in the car now - but if this is an original 383-330hp car - I might go back to a date coded 383

A B H L Q X
2 5 3 1 5 1

1116 4108 632 646 MWJ

Thank You
