Scream'n 318 ?

true story.... One of my brothers had a '67 convert Camaro with a built 396 rock crusher 4 - speed. Headers, aluminum intake, side-saddle 850 DP, etc, and he wouldn't race my '70 Duster with a 340, and I didn't even have headers. I drove both, he and I both knew... :D
I regularly played with a Duster 340 on my way to work in my '65 with a 68 340 in it. Id beat him every time to the point that he wouldnt even race me anymore. Mind you this was on a resi blvd and we'd take it up to about 60 and then let off but I'd beat him to 60-70 by about 3 car lengths every time. 3.55 SG 7.25 rear too! His 340 looked 100% stock, most likely an auto like mine. I beat a buddy in a Camaro with a 6.6 motor too. He had that weird diagonal carb mount Edelbrock torker intake.
