I'm getting everything together to rebuild my 250 and I'm considering changing my intake manifold and carb setup. I would like to hear from anyone that is using a single Holley/Weber from Langdon's or a Rochester 2G on the stock manifold, twin Carter W-1's or twin Holley/Weber's on a 2x1 manifold, a single 4-barrel on a 4-barrel manifold, or 3 Carter W-1's on a 3x1 manifold. What kind of performance do you get out of these setups on your engine?
I use the truck as a daily driver and it hauls light loads regularly and pulls the occasional trailer or heavy load in the bed. It typically cruises at 55 mph and less although starting in August it will begin to see extended drives on the interstate between college and home at 65+ mph. I'm also planning on installing either a Borg-Warner R-10 overdrive in place of the original 3-speed or changing the 3.73 gears over to a 3.08 gear. Thanks in advance for your input.
Edit: I'm also planning on using a Fenton split exhaust on the truck running to a single exhaust with a dynaflow muffler.
