Living with a '66?

I used my '65 barracuda w/ a 10.5 comp 340 in it as a daily driver for a while and it's livible solong as you can pay for the gas. with 95 or 97 RON gas you should be fine, in Cali we can only get crappy 91 and I was able to run the 340 on it alright.

As for parts alot of places like Napa still carry alot of the parts that you would need to keep it on the road. If not, many other later A-body parts can work sometimes. Body and trim parts can be a pain but stuff comes up on ebay and forums from time to time.

Hope that helps
