With such a light car I feel that stroker motors are too much.
I ran a, as close to, stock 427 FE first in my car and was very happy with the power to wait ratio with 360hp to the rear wheels. Cam came on about 3000rpm. Very controllable.
Due to engine problems I was talked into all new crank rods and pistons to get away from the 40+ year old parts.
482 is very fun but way too much for the street. I haven't dyno'd the car yet but she is a beast.
It is all in making sure you are pointed straight when you nail it.

I ran out of road quick with the 427 but with the 482 it is unbelievable.
I like it but for my next Cobra it will have a high revving stock stroke 427.
It is what I fell in love with 24 years ago in my first car.
