Hy Alex Arrow and guys, I must have been away in Oregon when this topic was first started. At any rate a little education on Canadian GMC and Chevrolet Maple Leaf trucks, Canadian engines on which the serial number begin with the letter "G" are 248s. GMC 9700 series and Chevrolet Maple Leaf 1700 series are more often than not powered by GMC 248 engines whose serial numbers begin with the letter "G". There was an option available back in the day to install a 270 engine in the GMC trucks 9700 series.
