this is my dads 1957 4 door bel air wagon. it runs a very mild 327ci small block chev with a 500cfm 2 barrel holly and small cam. the transmision is a fully manualised 2 speed powerglide with a 1500rpm stall converter, as for the diff we think it is a 3.55.1 or 3.7.1 nine inch. the interior is basically standard and the radio is still playing out of the original dash speaker. the exterior of the car is all detailed including the undercarage.i will be adding more info about FAT57 in a few days but for now tell me wat u think of her.
