289 and 5.0 have the same 4" bore.... its the stroke is whats different :-P

I am also considering a 331 stroker. My local machine shop says he can sell me a good 302 block for $100 if I have him do the machine work. I have found 331 stroker kits for about $800. How much block clearancing is necessary for the 331? I sure like the idea of 42 ci over the 289, especially if I can get if for only about $500 above the cost of overhauling the 289 bottom end.

block clearance? if you mean clearance with the crank and connecting rods to the block.... it should clear no problem..... they dont have the problem like those chevy 383 strokers do
