I don't understand the reply to my comment, but hope your classic runs (mine is in perpetual storage mode right now, midst of restoration). I almost wish someone would steal mine & come back to me with all the metalwork done, with a few thousand $$ of add-ons to-boot...
What I’m saying is that while reliability of the new engines has gone up, those figures are misleading. I am doing old cars not just for my health, but have done my spreadsheet homework on long term economics. If you aren’t driving the crap out of a car (like a company car), the long term costs are pretty decent for keeping the old cars running. The new ones cannot really be back-yard repaired and certainly not inexpensively. I can get all the parts I need for the 57 - overall cheaper maintenance.
