Still having issues with the cooling on my 67 Dart GT convertible, 273 4bbl, 904, 7.25 3:55. Still getting way too hot on 20+ mile runs, and burning oil. Pretty sure there is corrosion in the block that’s preventing flow, and likely a head gasket issue (some oil in the coolant).
Torn between seeing about having the 273 rebuilt (to the 273 Super Commando 275 hp specss) or getting a 408 stroker with about 400 hp.
I assume a pull, rebuild, and reinstall will run me around $3.5-4K ish,...
Rebuild or replace?
