Good merning JRT,Wow a 400 hp in a 65 barracuda !!!.
Wish my first or last car was that strong. :thumbup:
That's is alot of motor and I am sure he will never forget it.
The rear end will be fine and as far as the gear go's 3:23 would be something I would use.But give some of the expert's here a chance to get to you.
,Just give them time and I am sure help is on the way. :toothy7:
You can get some sweet /6 power allso about 185 and sound's nice.
