Who's put a hellcat in an A-body ??
not sure a full mod on firewall is needed the issue is the cooling lines for the super charger on the back of the intake, but someone has a redesign for that and I think is on here. I have a spicy 5.7 that i run my Cope racing Trans behind. So far no issues and i have not been nice to it. I run either a drag radial or a slick pending on how i feel when i take it out and how energetic i am. takes it like a charm. I would really like to do the 8 speed, but I will save that for another year.
