i just recently picked up a 54 f100 with a 223 and a 4 speed. I haven't had much experience with these motors other than my dad had one when I was growing up in his f100, and now I got some questions: 1. This motor makes power up to about 2000rpm, and then there is NOTHING. I can understand it's not a race motor, or a high rpm motor, but even in fourth on flat ground with a tail wind this thing doesn't rev over 2200. 2. Holley 1904 carb has a cracked glass bowl on it. I'm going to pick up another carb (buying it tomorrow) but is there anything I can do to ensure the bowl seals to the carb correctly, and the bowl doesn't break on the new one? 3. Lastly, I have been looking into the t5 conversion. Has anyone done this to a 223, and does it improve absolutely any aspect of the drivability? My trans works fine right now, but if I could raise the top speed of the truck with a t5 a little bit or make it a little more driveable it may be worthwhile. I have seen the kits online, but never heard any reviews or anything.
