This Source shows 49/51 distribution. Now I would assume only Kirkaham and Shelby/Kirkham cars are anywhere close to the original weight and spec. Not to get in a pissing match, on a 2150lb car, does taking 100lbs off the frontend affect the handling of the car? I am not pro or con iron vs alum. just asking a handling question.
I agree the Shelby Alum is the better motor, no contest and your knowledge of engines, well I really enjoy all the free information that you share.
My question is more of chassis/weight distribution and how it effects handling.
