im pretty sure that chevelle spanked your ass, theres no way a 454ss could outperform a 350, but your car is lighter, i use to work on my uncle’s chevelle with him all the time and we did some not so minor mods and that thing threw you back in your seats if you ever wanna see pics of it lmk i’ll show you it, but idk what work you have done to your engine but i would be nice to know:wave:
