I am looking to start a Countach build and am looking for advice relating to the chassis. I am on a budget with this build so I am limited on where I budget money for this build. The car will have a 600hp ls engine in it. Would a stretched fiero be able to handle that kind of power without twisting or is a tube chassis necessary for this application? I have some experience welding, are there any plans for the countach chassis floating around that I could use to build my own frame?
