SB torque plate

We made them out of 2 1/2 billet aluminum. My son used 2, One on each side on small blocks. I don't know the reason why but he does it on all race motors. He gets the material at a machine and metal recycle yard.You pay for material by weight. They were about $70 each You can get two out of each block of aluminum block.

He bought 10 to have them on hand. He is doing a subaru motor. He said he only needs one for that motor because its a split engine block while honed. we got lucky and they had the blocks cut in 28 x 14 x 2 1/2.

He just did a bore check on the mill and you can see the high spots at every head stud/bolt on a motor done without one. .004 to clean it up.

I will take some pics of the one tomorrow. He is setting feed rate for this new machine. He puts dye on the wall and it shows the high spots on a skim cut. Wait until you see these pics you will never hone a cylinder without plates again

Some shops have hot coolant going through the block while honing.
