No problemo.
I believe when we talked he had a lower hp 331...maybe 400-ish hp if I remember correctly. He was wanting to try to get up to the 500hp range, but that would make for a very high strung engine that probably wouldn't be that street friendly.
Going from a 3.46 to a 4.10 would net a pretty dramatic seat of the pants difference. No, you may not be able to flat-foot it in 1st gear, but I think one of the learning curves to owning a Cobra with more than 300 hp is learning to pedal a little bit.
It's a lot cheaper than buying a new engine too....hahaha
