Did you sign up at the "TheTurboForums" yet? That place looks pretty good for Turbo deals.

Here's one another guy over there playing with a BBF, I saw. Not sure what they have for Turbo Vender Tech. Support but looks like they have a wealth of in the Field Testing.

^ Note post #58. Another 460 guy almost burned on timing sprocket keyways. It's almost like they where made intentional by a Chebby guy to screw us over!

Definitely hit up the Turbo Forums. There are quite a few of us BBF guys over there.

^I bet you are skull and cross swords. The 460 world is just too dam small, Ha. Yea that place is good.

Don't quote me and I'll save you anonymity, if I am right.

Haha yep that's me. I have used that avatar for probably 20 years on various sites.
