It's not the record winning #21 that Pearson drove in Nascar to 11 straight pole wins, and still holds the Darlington track record for most wins

The #21 David Pearson set records with has a 429 and is in the Darlington museum... is restored, and looks beautiful. This 351 Merc is likely a tribute car of a fans from the 70's. It was at the Auto Club 500 very recently http://www.rowdy.com/content/profile/blog/29050/auto-club-500-pt-2-raceday-pics

Pearson drove from 1960 through 1986, winning three championships despite rarely running a full Cup schedule. With 105 career victories and 113 poles, only Richard Petty -- who made many more starts -- ranks ahead of him in either category.

The race cars on display at Symbolic's open house

This is a factory works MG, and the body is all aluminum

I can't tell what race series this competes in... the number 2 Miller Lite / PPG

I find the lack of thread interesting, rounded ends of the lugs, and wonder what the safety is in having longer lugs without threads.

on the studs; the round ends and blank lead-in would be for quick changes, with that amount of blank there is very little chance for a crossed thread and the round ends make it easier to get on target with the gun. As long as the nut covers sufficient thread I don't see any issues with safety.

Dan, I was wondering why the length... I recall that extra long lugs were a safety requirement, and thought it was to have the extra inch or so of threads... for the nut to have a hold on if it should lose the torque force smashing it onto the rim, it would then have some thread to keep that rim on the vehicle a little longer for the driver to feel or hear the loose rim, and safely get off the track.. that's why I wondered about the length of the lug... to have it bare is conflicting with what I thought was the safety feature of the extra threaded lenght. I love this, I get to learn from people who know stuff! I dig your explanation of the cross thread reason, and rounded lug end, I looked at those and immediately thought that was a good idea!
