This 1955 F1oo has been on the back burner for a loooong time. I got into building open wheel hot rods. I chopped the top 1" above the back glass, 1" through the back glass and 3" below the back glass. I did it that way to center up the back glass with the side window. I used the top center sheet metal from a 1956 cab. I think it is about 1/2" lower. I raised the windshield opening 1" up into the roof. I cut off the drip rail and added rod to look like 33 Ford. I love the SBC but more than that I like something different. Out comes the SBC [and the cold air induction] in goes the 312 Y-block. It is .060 over with a mild cam. I built the block hugger headers from u-bends not a SBC kit.
