The R302 tooling as I recall was getting old and we sold the last of our production blocks and Sportsman blocks. The Boss 302 was designed to replace both our race block and the Sportsman. For us to have rehab'd the R302 tooling would have been an inferior block for more money.

In regards to other posts I agree that piston skirts can make a big difference. We use Mahle pistons and have had great results.

Thank you for the explanation Jesse.
By the way, is there a way I can obtain a copy of the instruction sheet for the M-6010-R302 block?
I own two R302 blocks, however, I do not have the instruction sheet that contained all the particulars about the block, including the toque values for the fasteners.

Re: 289 better than 302 block for 331 build?

The instruction sheet for the R302 is a one page deal and is not available on the Ford Racing website. If you have a fax send me the number and I will send it to you. I would scan it if I knew how but my knowledge of computers is on-off-porn
regards
