What is needed to build a 7 second (1/8th) street car
Yes, if the tires aren't a hoosier quick time pro or et street and more of the BFG radial T/A or cooper, you're giving up a ton right there.
My biggest issue is the MPH, that's a direct hp/wt relationship. Tire won't make much difference there. 85mph is weak for what is here.
I'm also not a fan of strip dominators or M1 intakes. And I HATE HATE HATE those holley mechanical fuel pumps. Never had any luck with them, ever.
Goal should be high 1.5x 60' and find the missing MPH.
