It was MORE than enough for those bias ply tires!
No kidding...my first ride in a Mopar muscle car was a new 67 GTX 440 auto red with white interior
We were on the hwy doing about 50 MPH and when floored it smoked the tires like John Force and those tires were "singing" a few later we were almost Warp speed with the speedo sunk down around turn signal...
Ahhhhh.......That is what we all try and relive with these things--those kind of moments.
