Yeah, I remember Meyer Speedway, all right - my uncle Bill Blumrick #7 was one of the champions out there. I've posted a video of the 1967 Labor Day 100 lap Modified Stockcar feature on YouTube, and here's the link.
Bill led almost the whole race. Joe Plowman #28 had been on his back bumper the whole race and finally passeed Bill on the 95th lap. One lap later, Joe's engine went kablooey! Bill retook the lead for 3 more laps, and HIS engine crapped out. Charlie Schild #1 took the checkered flag.
Bill was sponsored by Frizzell Pontiac, off the Gulf Freeway at Gulfgate. "Whale Of A Deal!" Therefore the "Whale Tail" on #7.
