273 commando cam

Are you looking for a solid or hydaulic cam?


I had a 273 but wasn't running the compression you are going to have. My car is also a 4-speed. I would suggest the old school .474/.474 Mopar Purple shaft. I ran it with a compression around 8.5:1 and it did fair. It was a tad bit over cammed. It does not take much to over cam a 273. Believe I know. But with the 10:1 compression that cam would work really well I believe. I switched out to a Summit cam .441/.441 and that brought the low end torque back up.
