I was trying to look up the problem with that block and Ed hit
it on the head about the webbing, it should be fine but the article
said they would not waste their time on it, and i don't know if it
was the gen V or VI but you had to use the stock timing gear
due to clearence would not allow the use of a dbl roller, they did not
have a after mkt cover for it, i could be wrong but i think it was
one of those blocks, they made changes on the 572 block.
Ed i admire the biblical verse i remember reading:
" For when you speak my name and spread my word, they will
throw rocks and close the door on your face, but when you
have come to rest with me, you shall have eternal life with me"
man thats nice

spread the word
