I've got a Scat crank in a 383 cid engine I built about 6 yrs ago...
Although the crank was new , my engine guy had the crank cut 10 - 10 to straighten up the clearances for the bearings. The crank was not ground correctly. I hear some of these cranks are still "out" sometimes?
I have a new set of old design pistons ( hyperutechnic) for 5.7 rods... I may assemble another engine soon for an old class C chevy motorhome. I hope it will tow better than the 350 motor did
