I usually have 862's, 317's and 706's. All have been freshly rebuilt. I will sell the 317's, 706's or 862's for $550 a set. Will knock off $150 from the 317's if you have good cores, but only if you buy a pair of 317's. I will knock off $150 if you have good 862 or 706 cores to turn in. I will no longer accept CastTech 706 cores unless you let me pressure test them first. I will knock off $250 for 243's, 823's, or 799's. Calls are best. 801-244-1599
