general rule of thumb: duration makes HP; lift makes TQ.
The 509, with its duration advantage will make its power up higher in the RPM range, and probobly more total HP. The Lunati with a little less duration, and more lift and faster lift profile will make more midrange torque, and probobly be a better all around street cam.
My choice:
Race only: MP .509
Street/strip: Voodoo.

Can you teach me more about cams please?LOL Cam selection depends on more factors than the op posted so any answer is a guess at best. The Lunati isn't the most modern lobe design,but I have seen a direct TRACK comparison in a similar combo and the MP wasn't better at any point. So all I have is a slightly edjucated guess.
Metcoll, asked a Direct question. Witch cam would be More radical and have a Higher HP peak.
No doubt!, Between the two it would be the 248* @050 MP 509
As far as performance at the track, Now That, would depend on the "Combo"
But even viewed with that taken into consideration, IF, Both combos Optimized, IMO the 509 would still win. And Optimized is a Key word here. mike

In this case the .050 numbers are the determining factors that will decide whether or not witch cam is More radical or has a Higher peak HP. In the engine as listed there will be a measureable difference between 240*@.050 vs 248*@.050 in reguards to "HP RPM peak" and the Radical Effect. The Radical effect not always being a good thing. As far as a Optimized combo, He didnt ask about that, your right. So we will leave that out of the equation. If Metcoll wants the best cam for the combo he needs to give more info, mike The actual question as to

which cam would be more radical or make more peak hp...mopar 509 cam or lunati240/250 520/547 hydraulic...030 440 six pack pistons 452 heads (3-angle valve job standard valves) rpm intake 750 dbl.pump & 13/4 headers...
question is what is the rest of your set up? both cams are going to want some stall and gear to work. The 509 will need a 3200 stall and at least 3.91's to get it up intyo it's power band. Between those I'd take the Lunati.

Shows most people in hear don't know crap! The old as people call them MP cams were actually way ahead of their time. the were true .904 lifter cams taking the big lifter and using faster ramps with less probelms when all the others just used the cheby lobes fitted to a mopar engine blank.
But woo now many of them use the marketing magic of wow we use the .904 lobes making use of the mopars bigger lifter to do X and y!
The old mopar cams properly installed and for the motor and Torque converter were and always will be killer cams or mild if that is your flavour.
Everybody sells a copy of the 509 !! Why because for a stout street cam it still works!!!!!!!!!!!!!!!

Thats your oppinion and your entitled to it,but i've run the .509 in one of my previous 340 and was not impressed with it whatso ever,i've also run the .484 and thought it was another dog Mopar cam too..by the way the correct spelling is HERE!!!

Let me start by clearing up a few things. The MP 292 measured @ the same point as the Lunati(and the lunati isn't a Voodoo,but an older Legacy lobe for an .842 lifter) measures 305 degrees or so,since the MP cams are ground by the cheapest source of the week on gang grinders(lowest for consistancy,but very fast and cheap). The MP lobes are NOT .904 lobe!! They will function with a .842 lifter,sorry guys,I'm really not trying to hurt any feelings but why spout garbage info??I'm not bashing the MP cam and have run them,I've also AB tested with other cams. Carry on and keep the internet thriving.LOL

Well stick to spelling as you motor skills seem limited. First your comparing a 340 to a 440 100 cubes is huge on the way a cam performs but I know you don't understand that. with the right advance and things know only to us guys that can't spell but know motors I could have made them work.
Course anal retentive internet spelling correctors are so 1998!!!

Lunati makes about 8-9 more h.p and 2-3 ft lbs more than the .509 ground on the 108 LC. The .509 112 LC version is about 6-8 h.p. less than the 108 LC version. Almost identical performance with the same set up.
The new 904 lobes make only slightly more peak h.p. however the difference is torque under the curve.They kill the old cams there.Esp in a basically stock engine.Torque is what you need to move heavy cars.
Leave the gun.......take the Cannoli's....Mike
