The problem I had with the 216 6 cylinder is that it had a poor bearing design,
"babbit" style and with 80,000 miles, the engine was nearing the useful end of it's life. And a local rebuilder was guessing $2000-2500 to rebuild it, not counting any items to increase horse power. Yes, I wanted to remain close to stock, and I drove the tar out of it for a year, even towing my '57 Metzendorf
3 hours to a show in Illinois, but that engine didn't like it much. Hell, my light weight '47 Kit teardrop made it struggle in the hills of Brown County Indiana.
Enter a friend who just rebuilt this 283, and had nothing to put it in, and sold it to me for less than half of the 6 rebuild price. Since it is still a fairly vintage style engine (not a 350...which in my mind would have been sacriligious) I jumped on it. A 250 or 261 would have been cool. but the timing was great on the 283. I still have the T5 5 spd and just love the heck out of that.
