    JD 6-1 powerblock re-sleeve?

    Strokedpoked The casting hole and sleeve diameter at the top of the TSC 6-1 Powerblock was 6.563 inches and they ran that diameter to within 1.5 inches of the BOTTOM face of the block where the outside diameter of the sleeve increased about .003 . Then you have that big ledge with a diameter...

    Nail on the head! Indiana Ken. HP is a measure of the RATE of doing work. Work = force x distance . The horsepower measurement takes a look at the total work that was done over a given period of time and then says ok WHAT TIME PERIOD DID THAT WORK OCCUR OVER. One "horsepower" is doing 33,000...

Here is an example of a six and five eighths bore 1951 G with a 8 inch stroke running a 70 gas powerblock that had the old sleeves pressed out and then had the casting bored some to accept steel sleeves with a bigger...
