Is a MP 509, 292 purple shaft a decent cam on a supercharged motor

IF that is a crate engine, It ain’t a MoPar crate engine.
I’d run the other cam in a second flat. The 292 Purple cam is more than likely to be on the 108.


The early crate engines were the 360/300 & the 360/360. I forget what the 300/360 had for a cam. But the 360/360 -*IIRC*- used the MP Purple 284/.484 Hyd. cam. I gave away all my old books to friends and old club members. So I cannot check for the particulars.

That cam you list is for the roller cam 360/380 crate engine. I’m not 100% sure they used the Hyd. 292.
It is a good bracket cam. Very basic, performs well, even with stock heads though a good gasket matching and more importantly a bowl porting really help that low .509 lift cam to go. The cam seems to like a good bit of compression. But bad for adding pressure. If it was his only cam and was ready to run I’d just say use it, or, IMO, better yet, sell it and roll the money over into a better cam.

I still think the MP Purple cams are good for brackets. Not a big fan of “that” one in the street. BTDT, not thrilling unless it was at WOT. Even worse in a heavy E body.
I’m starting to rethink this whole project about now. The 360 crate motor is a 509/292 flat tappet and since the motor is most of the way together I might just go ahead and drop it in my old Duster bracket car (naturally aspirated) and use one of my magnum based 408 short blocks to build my son a truck motor. I have 2 408 Magnum short blocks that were built for a supercharger so the only obstacle I have to get around is a magnum style head with LA intake bolt pattern. I’ve got some EQ heads that’ll solve that problem. I’ve got 4 or 5 Magnum roller cams that have better profiles for blowers. Plus the Magnum short blocks are forged piston and cranks, wasn’t certain about supercharging a crate motor with Hypereutectic pistons anyway.
