Some good reading, I didn’t recognize a single member on that thread, my how time flies.
Unfortunately, most of that information is no longer relevant with the Turbo system we have now. I have been studying this for a while now and do believe it worth a least a try.
The mounting and plumbing are probably the largest issue. With the 235/261 having both the intake and exhaust on the left side of the engine space is at a premium. A cross over tube on the exhaust could move the Turbo to right side and allow for more room. The oiling is a major factor, 235/261's are not known for their oil pressure. Some modifications would be required.
Camshaft selection and valve springs need to be researched. Head work as well.
The carburetor is another concern. Using a Blow thru design would require a much larger CFM. It would also need an adjustable regulator and stronger fuel pump. All of these are workable nowadays. The Holley 500 2 Barrel seems to fit the bill closely. It has 375 CFM, the metering block allows for easy modifications and an adjustable power valve is available.
I have 2 of the Turbochargers pictured above, they are from a 4 cylinder Cummins Diesel. These are Military Surplus from Planet.Gov (cheap). They already have a waste gate mounted and are rated up to 8 LBS of Boost.
I may do a mock up of this system over the winter with the 261.
