'61 would be a good year for Pontiac drag racing. I think Lloyd Cox won the S/SA class @ Indy. According to a '61 Winters list I just saw, Pontiacs won D/S & C/SA, I believe it was. Not familiar with either drivers' name. I'll try to go back & find that article & post a link.
In that article I saw something for the 1st time, that I should have known. I knew that Mickey Thompson had lots of Pontiac powered drag cars. But, this article shows him actually driving his X/D Pontiac 4-cyl powered front engine dragster. And, he actually won his class AND "Middle Eliminator". Says he had 3 of these 4-cyl dragsters entered in that race.
For any who don't know, that Pontiac 4-cyl was known as "Half a 389". It indeed did have one bank & head of a 389. I had one of these in my shop for a few years, storing it for a friend. It came out of a dragster that ran at our local track. But I don't remember ever seeing it run. Anyhow, IIRC, it had aftermarket forged rods, hi-comp dome pistons, either a RAIV head or an SD455 head, & a healthy lookin solid roller cam.
This was also the 1st year of the 421SD engine. Hayden Profitt drove a M/T SD421 powered '61 Pontiac to the OS/S class win @ Indy that year. I've read that the OS/S class became the FX class in '62.

Maybe some of you guys can help with a couple of the Pontiac Stockers on the list. D/S winner is Allen Hart. No year or model listed. C/SA is Bob Battelle (sp?) 4th letter don't look like a t or an l. Just assuming it's supposed to be a t, or maybe an i ? Anyhow, would like to ID what Pontiacs they drove. Notice all the Stock class winners that were DQ'd.
