Valiantmike,
I would suggest a XE284 with the 4 spd. or the XE284HL both will work great and get you some lope. But you'll have to check the piston to valve and the retainer to guide clearences as the guides will have to be machined. If this is too much for you then go down to something in the 268 range. But you'll still have to check the afore mentioned things.
