Barry-R MSD finally came out with a dual pickup dis that is to take the place of a crank sensor. On your pistons is there enought air gap to keeps the rings from cooking. I want to do the same setup for motor number2. 4.25 crank, 6.7 BBC rods, Stock deck height on the shelby block. I don't want the
oil rings in the pin hole. Your pistons come with coating to protect the sides of the cylinders and pistons. Do you have piston skirts to keep piston slap to a mininium? What are a set of custom pistons going for and is there a part number for either a 4.25 or 4.28 bore. Are your pistons forged or cast? Thanks for the info. Rick Lake Ps. I want a 11.0-1 compression with 85cc heads and 1020 head gaskets.
