Post 300 catrbs

I'm replacing a fried 351M enigine in an '81 F-150 with a 300 ci 6-cyl. (also replacing the C6 transmission) Can the 2-barrel carb on the 351M be adapted to the in-line six without going to a great deal of expense and bother? Would it be worth the effort?

I'm also considering other modifications. My goal is to build a truck that is as rugged and dependable as I can make it, and still be easily maintained and repaired under the shade tree. It will get driven on bad roads, rarely off-road, and frequently up steep hills. I'd like to get as much pulling power out of the engine as I can, without defeating the rugged and reliable requirement.

Too much trouble and hassle to retro fit the carb. Your better off with one made for the six because it will be calibrated for the six.

Some people have put 2 barrel carbs on but I'm really not sure if there is a big benefit unless your willing to change the intake system and exhaust. The 300 six is one of the best pulling engines you will find. I just finished pulling a 24 foot fully loaded U-Haul truck out of the mud with my little 300 six 4x4 and the tires did not even spin once. Find something to beat that?
