[quote:24nexv71]I see it is a 57 model. How many cubic inch 185 block or otherwise.[/quote:24nexv71]
Actually it is a 57 paint scheme. Serial number is "amoung the missing" so we aren't really sure what year it might be. Dad bought it new in fall of '55.   Original block, 3.5x3.75, punched to 4.0, stroked to 4.0, should make a 302 same as Super 99 gas,  1100 MF, gas, or 1850 gas.  Real trick was a 4 main bearing crank.
