The 283 rods will work and your crank all you need is the correct pistons and the crank would need to be rebalanced as the pistons are heavier then the stock 283 pistons.
The block may work but the only way to tell is to have it sonic tested to see how thick the cylinders are.
There are better after market rods out there then the old 283 rods.
I have a brand new small journal crank 3 inch stroke and a brankd new set of 302 standard bore 11:01 pistons and rings and a set of 327 rods if your interested PM me,
