Just wanted to know if any of you opelers out there have attempted to install or ever seen a toyota supra 3.0 L inline 6 in a gt. I have a 69gt and wish to get alot of HP without going with a v6 or v8. I could leave the engine stock and 235 hp. I know that the gt rear end would not hold up for very long. I was thinking about swapping with a rx7 or supra. Any advice, suggestions, or comments would be greatly appreciated.
