I-6 250 swap ability?

[yossarian19]

Hey folks,
My truck currently has a blown-up 235 engine in it, bored .040 over w/ spun crank bearing on #2. Needless to say, I'm engine shopping.
A guy in the nieghborhood has a 250 motor as a long block, no intake or accessories.
How much if any of the 235 stuff will bolt up to the 250? Is it a direct swap? I don't want to spend too much swapping in anything with a carb, since the long term plan is to go LSx. I just need a running pickup truck to collect the parts & time to save some cash...

I have a bellhousing on hand to put a V-8 in front of the existing transmission & pretty much zero other parts on hand.
