5.7 hemi swap in a non A body?
Trash truck went back to the track with EFI. 100% stock truck computer with no tune. I Datalogged with HP tuners.
In a nutshell the factory EFI intake is superior over the carbed modman. We knew this!!!! We are faster now!
Made less MPH in the 1/4mile then when it was carbed but I had adjusted the timing on the hemi 6 and the carb tuned to 12.3 with a wideband.
Made 2 mph more with EFI in the 1/8 mile over my old timesheets.
60ft was slightly better but only by a hundredth or two.
It was hot tonight! 94 degrees and my intake air temps were 122 when staging. Hope to go back in a few weeks when it’s cooler and I will have made a tune to try.
Made the 196 mile trip at 27-2900 most of the way and delivered 13.4 mpg. Enjoy and laugh at my slow times
