Burro,
Since you have 4 engines to work with I would pick the one in the best condition that starts the best, the 329 would be low on my list as they are notorious hard starters.
Your project will be a little more difficult since your lengthening the tractor. Have you considered trading an engine for a 4 cylinder?
You will need a rear engine adapter and the front pump support from a 4030. You will also have to have someone competent modify the flywheel to fit and pilot on a spacer that will have to be fabricated to move the flywheel rearward .500". This is the real critical step, it is very important that the spacer run true and the flywheel is rebalanced after modifying.
Also, you will have to figure out which water pump to use because the big one on the 6 cylinder won t line up with the radiator.
I also imagine you will need to use a set of 4020 frame rails to start with and modify those. Maybe you could use 4030 frame rails too, I m not sure about those.
And it is understood that you will have to lengthen hydraulic lines and some wiring and do something with the hood.
What you ll be putting together is basically a dry clutch synchro 4030 or a power shift. It ll basically be an Argentine 3420.
My little 239T puts out 115 hp on my dyno with absolutely no smoke. It s a stout nimble little tractor.
