Welcome to the forum.
Good luck with your build.
I agree with the thoughts above.
Once you decide on your supplier then talk to the engineer. You have the option of going either Gen. motor or quad cam Ford. Both are easily fitted and the supplier will have all chassis work done to suit.
So firstly, think about what engine. Pick your supplier of the kit and keep talking.
Kits such as those supplied by Warrick and Classic Revival are not new to the engineers. Additionally, once you decide on the kit talk with people here who have your kit and they will guide you through the process and the build.
Again good luck.
