I pulled the original engine (274,000 miles) out of my 68 mustang convertible over a month ago and took it to Fonse Performance in Erial NJ for a full rebuild. I get the engine back tomorrow and im starting the install right away. I was told that the engine could make upwards of 300 horses after the rebuild. So I would like to get some knowledge regarding the subject if anyone feels like schooling me. Should I just get another autolite 2100 and which choke should I get? The last carb's choke was just a black circle on the side of the carb. I was told that the electric choke replacements are the way to go.
