Thanks for the welcome! As I said, I bought this car new in early 1978 as a leftover. It had a 318 with overdrive 4 speed transmission. It was pretty weak actually. In those days everybody wanted a "Smokey and the Bandit" Trans Am so going with the Road Runner was a leap of faith on my part. Not long after I got it, I swapped out the 318 for a low miles 360 I found in a boneyard and put 70 340 heads on it with a Competition Cam. I also swapped out the overdrive for a real A883 and added headers. Ran that way for a while then swapped in a 70 B body 8 3/4 rear with a 3.55 sure grip. Ran good like that until 1981 when gas got high so I bought an 81 Dodge Omni Charger as my daily driver but kept the Road Runner. I wanted more and found a guy selling a motorhome 413 with less than 2000 miles on it because the motorhome burned down. Engine was good. Word of advice. Leave the motorhome 413's alone and go for a 440 if you can. I wound up swapping everything out of the 413 with 440 parts and still wound up with a nice 413. Money I would have been better off spending for the extra cubes. Just sayin'. Anyway, the bottom fell out of the economy by 1982 so I put the Runner in storage and joined the Air Force. I took it out of storage in 2008 and now it's in my garage in pieces. I'll get it together one of these days.
