Terry, No one knows that more than me and I hate that it has come to this. All my stump pullers still use 130 seat and 330 open, the extra rpm these spring pressures allow are no advantage to me. On the other hand if I don't play by the new rediculous rules the L88 would be left way behind.--------Danny

Those $279 Crane Gold rockers for Stock don't sound so bad against a $900 set of stamped rockers now do they?

Jim, I was just wondering when it became legal to weld or customize stock rockers??
When we went to Indy in '04 with the 350 Buick, I had already split a couple of rockers at the shaft hole. I wonder how long we would have lasted in teardown if I had welded a bridge piece across the top of my rockers to strengthen them up?

Let's do a poll:

5 seconds

10 seconds

15 seconds

Mark, who knows? All I know is that there are many things out there that are in now and no one knows why.....
