mshred, haven't we been down this road before lol, I'm sure i gave you the rundown on my 71 "no thrills" 71 Swinger, junkyard 360 magnum, RHS heads, re-ground roller from bullet, Crosswind intake, 650dp. 3.73 gears & a 2800 11" converter, drove it too & from the track (100 miles round trip) several times & pulled off 12.5s shifting at 5100 RPM, With a converter change & some more tinkering i'm sure 12.3s were there, thats flyin for what it was, a NON stripped all steel/glass 71 Swinger, granted i'm a light weight at 145 lbs., so that helps, I ran a Sniper system pilled for 125, on my best run (but still not great) I pulled off a 7.58 @ 94 & change, I personally would run a Roller, **** all that flat tappet ****, sorry Moper, I also ran the thick factory head gasket with the factory pistons, my compression was close to 9.1, If you want to know more about doing something like this & ideas, talk with LXguy, His factory dressed 71 Swinger runs 11.7s with a "junkyard" 360 magnum short block.
