When I built the truck with the 261 7 years ago, I moved the radiator foward.I relocated the radiator side brackets,enlongated the filler cap hole in the nose piece,looks like it will clear with room to spare,easy.
Buzz, I nixed the home made intake,bought a 4 bbl intake from Patrick's.But I did make the headers,didn't spend any time on finish grinding,no one see's em anyways,lol.The header isa foward dump to clear the steering box, using 3 inch single pipe and muffler.
