I am looking for some opinions on manufacturers who do the turn-key cobras. Iused to live in Massachusetts and visited Factory Five and they seemed to be a good outfit to deal with. I also noticed some discussion here about Rolling Thunder Racing and how they may not be a legitate company. I am looking to buy a 66'- 67' Shelby Cobra with at least 400HP and would like to know if anyone has any suggestions on a good company. I have also looked into Shell Valley and was impressed with what I have seen with them. Any input would be greatly appreciated. This is a big investment and I don't want to make a poor choice.
