It's a good thing nobody was injured period.

Yes, the driver of the Chevy11, the starting line crew, and spectators were all very fortunate.

Let's look a few things here:

Mopar ring gear is attached to the converter. I can buy them from a number of sources. Not SFI certified, in any case.

Fords have 4 bolts on the converter..Possible a stronger deal.

You cannot modify an SFI part i.e. cutting a window or a door in a bell housing. How do balance an approved flex plate then?

Turbo Grand National Buicks run way run way down in the 11's., as a V6 combo.
Same for Saturn Sky and Pontiac Solstice Eco-Tec 4 cylinder combos in Stock.

Seems to me that this should be done by ET, rather than singling out a particular brand or two..Maybe 12 flat ET..Not by class or eliminator like the stupid roll bar rule.

Just a thought or two, but whatever anybody does , don't show this post to the NHRA lawyers or insurance company..They're all pacified now.

Yac. Get back over to the Hamb and keep us all straight on the Jr. Stock thread.�� That'll run off the rails if you stay away too long.

Tommy, I just call 'em like I see 'em...
The Tokyo Rose deal? Easy peasy ;-)

I used The Wheel from JW transmissions on my powerglide for years. I guess some people like a lighter weight but it was consistent and heavy duty, I trusted it 100%.

Mark, you don't think it might have more to do with RPM rather than E.T.

It might but would be hard to regulate that in an equitable manor...Re: Eco-Tec 4

I don’t think the ring gear knows any difference if it’s being spun to 7000rpm by a BBC, SB2, SBC, V6, or a 151.

They'll check it when it's laying on track or out from under the car. Then you will get a nice letter and a fine.
