NHRA Junior Stock That post, made by someone else, not me, says that slicks were not allowed in 1973 NHRA Stock. I think I can agree with that. I took my car off the street, & put it on the track in '73. Our local track was running what I believed to be NHRA rules. The tower had a div 4 Good Guys symbol painted on the side of the tower. I have pics of my car, with me bolting on some wide M&H hard rubber street legal tires, in the pits, after towing the car to the track with a '68 Caddy & a tow-bar. Our track ran off track records, rather than nat records or index. I lowered my D/S track record several times. The local track called our class "Top Stock". The real street driven cars which were actually driven in the gate could run "Street Stock". My car's engine was still almost exactly, as it had come from the factory. Had an aftermarket timing chain set. With the original 3.90 gears, close-ratio Muncie, & hard tires, the best I could run was 13.90's. But, for 1974, NHRA made some soft compound tires legal. I've actually read where someone said those tires were made legal by the US Nats of '73. Maybe some of you guys remember. Anyhow, I bought a pair as soon as I heard they were legal. Swapped out my alum flywheel, for a new Hayes steel flywheel & clutch. Those changes alone dropped my ET by about 1/2 sec. For the '75 season, 9" slicks were legal, at least at our track. So, I suppose those tires were only used for 1 season. Below is a pic I found online which IIRC is exactly how those tires looked. Any of you guys ever run those tires ?
