I have a MR1 block, Ohio forged crank, Ross forged pistons, Eagle rods, High port Heads, Solid Roller Cam, no expense spared. It has done 1000 miles and the pistons have picked up in all bores, really bad in 3-5-7 bores.Suspect Incorrect bore to piston clearance. All ring gaps were set right. It was assembled by me as a ready to assemble engine package. Any one else had a issue with one of these blocks so I have some reference when I get back to the engine supplier. Thanks Bob in Australia.
