suggest a camshaft

[0X01B8]

So, I've got the notorious Purpleshaft .484 cam in my 440.  I decided I'm just gonna go ahead and replace it and stop trying to treat the symptoms - low vacuum, almost impossible to tune the carb, etc.  I'd rather not 'cause I've never done a camshaft before, but I guess I'm up for it.

I notice there's a newer purpleshaft 484 (P5007697) but with "revised centerline for improved street drivability."  Should I even risk another one of these?  Does anybody have any suggestions for a replacement?  Despite my problems with this cam I've been happy (sometimes terrified) with the engine at WOT.  No complaints there.

Anyway, thanks and here's my config:

440
Stock intake & exhuast - hemi mufflers
Carter (Edelbrock) 750 AFB
TCI saturday night special torque converter w/ shift kit
3.23 gears

I like the .484 cam for its sound, if you spend alittle time on the timing curve & then set up carb, i think you'll be happy, any perf. cam you get, you'll have to do these things unless you stay conservative on the dur. & spread out the LSA to a 112 minimum, but you will not get the rumpidy-rump like on a 108-110 LSA, now i went with the larger summit cam, never ran it before, it performs well & pulls 15 int. vacuum, for the 90.00 bucks for cam & lifters, its a good deal, but it has a fairly mild idle

465/488 lift. 224/234 dur. @ 50  112/114 LSA, this is also a very good nitrous cam

There are a lot of better options than the MP purpleshaft profiles.  Engle makes some really nice street profiles that will idle better and make lots more power and be easier to tune. The k56 grind would be perfect for your car, inmo. Another member just installed one in his car which is similarly equipped and had excellent results.

jg68 - yeah, I love the sound.  It's fun to have a new passenger with me, sitting at a stop light the whole car is just rocking back and forth.  I've had people look at me all worried and ask 'IS IT SUPPOSED TO DO THAT?'

ron- that's a great thread, thanks! I think I will go with the K56...  Carbs & timing are pretty much like voodoo to me so anything that might make it easier is fine by me.

I got the cam used and have had suspicions about it being worn or screwy ever since.  I don't know what I was thinking at the time, i mean, i was already spending money on the car like the proverbial drunken sailor, so a few bucks wouldn't have mattered.  sigh.  It will at least give me the chance to take care of some other issues will the motor is torn apart, so that's good.

You could always get the elec. vacumn pump, it works for the power brakes, '69 headlights, etc.
