450/455 SBM Purpleshaft

hydraulic?
Pn 4462761?
that cam is 268/272/110 and 228/231@050 and 450/455 lift
I think all the cam companies have a copy of that, and if not, then at least close to it, like 268/276/110 OR a 230/236@050
Or
the old 340 cam was
268/276/114 and 228/235@050, 429/444 lift

I guess it depends on your application
Yep hydraulic. I was talking to Jim at Racer Brown about having him make an exact copy of it because I pulled the original cam our of the engine, just was rusted. Figured I would see if someone had a NOS one before I had a copy made
