I knew a couple of ls6 chevelles that would beat a big block mopar and your unbeatable hemi no problem.. I had a 69 442 400-360 hp with 3.73 gears, started out stock about 14.30's and with a little work got to run consistant 13.80's on "real" street tires, and I felt like KING KONG. I could whack about anything I raced on the streets, 440 GTX's 396 Chevelles,Novas and Camaros, Cobra Jets, Didn't matter, until I ran a Hemi Orange 6 Pack Super Bee and He made a believer of me . I said "I'm a gonna get me one of them there Mopars without hood hinges" and I did, but mine was Green. With a small amount of work, the 6 packs would run deep in the 12's. Probably the best "Factory Street Racer" there was. These cars held the National records in their classes back in the day, before all the factoring crap and "replacement parts" they allow to brand x today in Stock. lol
