6-pin or bolt on?

Increasing the weight by 10 to 15% (or more) is getting too far way. I ran with some 2200 lb, 300 hp Miata's (turbo) on a technical 16 corner course. Half of the corners were in 2nd gear in the Mustang. They never got out of 3rd. I followed them as well as I could (terrible) to try to get some gage of what a 289 might be like (similar weight and wheelbase) They were amazingly fast in the corners. Much less weight to slow, much less lateral weight transfer, and a lot of momentum left on exit. I plan to try running with them.

With regard to handling, we reported that the Cobra, with its light 2020-lb. curb weight and excellent 48/52 balance, was good, but could be tricky: "With so much power on tap, the inept or inexperienced could get into considerable trouble, but a middlin'-good driver can certainly get the car around a race course in a hurry. ..................................................

2020 curb Street - 2400 is 20% - 25 is over the top.

un-sprung weight => lateral weight transfer

Form follows function - build it lite

If its a 427, do what you will.
