Installed a similar MP .509 hydraulic cam (straight up) in the stone stock 440 short block (original engine,10:1 comp.350 hp version)factory stock 906 heads,used an old CH4B Eddy intake,ootb untouched Holley 750 3310 vac.secondary carb, MP ignition, Hooker 1-7/8 headers I believe...full 2-1/2 in. exhaust, with cheap turbo mufflers, 3.91 sure-grip with rock hard radial 60 series tires out back... Best Quarter mile time? 14.19 @ 99mph Milan Dragway MI. around late summer 1987...in a 4600 pound boat!!! used to street race it some, and whupped a (brand new at the time) '87 Grand National very badly on Gratiot Ave. one memorable summer night! wish I still had that car. Plymouth Makes It!

I like the .528 but I still think a more modern grind can be better depending on the package. Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

I agree but the engine I am going to try it on is for someone that doesn't need the fear of using a cam ground to take advantage of the .904 lifter. I have an Engle KV-1 that I think is similar to the .528 that I want to put in a stockish 383 to see how it runs , I had it ground up for a 432 F.A.S.T. stroker and had the lobe sep spread to 112 to bring up the idle vac, but I need to put that in something with bushed lifter bores ...

I did tons of dyno testing and never found anything that worked better than the .528 cam. Andy's done all the work, and I see no need to re-invent the wheel, so I'll be swapping to the .528 cam in my 496 stroker with manifolds, MP452 heads, and six pack. 4 speed trans. Should I advance it a couple of degrees? My compression is purposely low at 8.82 (measured). This is the land of the free because of the brave

I drove it everyday It was in a 3500 lb challenger.... with a 4500 stall 3.55 gears car ran 12:37 at 108MPH...That cam in a big block would be on the mild side....Just my opinion..my motor made about 390-400 horse 65 DODGE CORONET 440 INDY EZ HEADS STRANGE S60

The .528 is mild enough that the six pack tuning shouldn't be too hard. You'll need to recurve the distributor a little but that should be about it.
