273 Commando or Not?

If it is not numbers matching original formula s like my 65 you can do anthing with it to make it a good driver. Mine now has 318 dressed up like a 273 4bbl. Looks original but runs much better than 273 ever could. It is much easier to build a 318 and much more available hp. Most people who look at mine cannot tell difference unless I tell them! I have black wrinkle valve covers and 4 bbl intake, engine painted red. Looks great and runs great! Lots more build options for 318, cams, heads ect! I have converted to electronic ignition, which your distributor looks like and dual exhaust. No formula s stripe yet but when body gets finished I plan to put stripe back on it, mine was originally blue as it will be again with white stripe I do like your silver color however. It should have a tach left side of dash if it was an s car. Mine also now has dual brake cylinder and front disc brakes, much safer to drive. Still manual steering and brakes but not an issue as it handles very nicely with front sway bars which are original for this car. Mine had a 273 but was not original so we made the change to 318 for hp and future possbilities at strip. I want to be street/strip eventually. I also have nice rally wheels to put on when I can afford the rubber, I have seen some others with this and it looks very cool with the ralley wheels!
