This is EXACTLY what I want to do, so I'm interested in hearing some opinions as well.

I am doing a swap right now too, it depends on what 4 speed tranny you are going to run. I'm going to run the later 68+ sm465 in my truck with a 350 in front of it, instead of the 67 down sm420. The only issues I have run into so far is the transmission floor sheetmetal is going to have to be swapped for a taller 4speed on the floor style, the gas pedal supossedly has to be changed, and I'm switching to a hydraulic clutch form a 85+ chevy truck bellhousing that is made for my tranny. I hope this helps, let me know if I can be of any more help.

so i decided to keep my 250 and 3 speed set up because my 6cyl runs too strong i'm just thinkin about camin it and gettin a 2 barrel intake and headers... i'll put a 350 in it when i blow this one up so it will probably be a while
