I recently purchased a 67 Barracuda fastback. I want to make it into a nice streetable fast car, but plan on occasional bracket racing. I have access to either a 1972 340, or a late 70s 360 (from a Ramcharger). Which engine would suit my needs better?

It won't exactly be a daily driver, but will get driven a fair amount. A cam, compression boost, headers, maybe some head porting, will be in the plan somewhere. Any opinions on which engine would suit my needs better?

Also, I already have all of the disc brake stuff off a 73 swinger and the k member, plan on a sway bar, new pittman and ider arms. It currenly has Manual brakes and steering. Will I need the center link from a 73 up also? Is it the same steering column if I use the 73 k member? Are 73+ V8 and slant six center links the same?

I recently restored a 73 Dart Slant Six car, it was kind of my practice car, and I learned a lot, and I want to get the Barrcuda right the first time.
