273 Commando Engine Clone

You can get the Commando/Charger 235 hp cam a couple of places. Racer Brown can grind one close, I just ordered one. I think Cam Craft has one also. The Commando/Charger cam is very small, .415 intake lift and 203 duration @ .050 with .425 exhaust lift and 207 duration @ .050. All 273 engines had solid cams and rocker gear from 1964 through 1967.

Commando/Charger 273's came with a Prestolite dual point distributor, Single plane intake, AFB 4 barrel carb, cam, valve springs, 10.5 pistons, 2.50 OD straight thru single exhaust, unsilenced chrome air cleaner, and the black krinkle valve covers with aluminum fins and spark plug wire holders.

I would not run 10.5:1 pistons on the street today. We built a flat top piston Commando 273 with the Isky E-4 cam with no extra parts that made 266 hp on the Dyno.
