Yep you see the diff between his times in the 1/8 compared to JOHN times and both have the same mods except the 6.1 has stock heads and same tuner except for the engines. 6.1 compared to 426. There race wt is about the same and i think Sacramento is about the same in traction as Irwindale and both DA were at 200 ft. 1/8 mile = 6.1 7.82 & 426 was 7.61 & DYNO HP was 6.1 420 & 426 was 480 on the same dyno.
