My '69 Charger R/T that I had, I went and put in a .509 Purple cam, and installed a Summit Racing Double roller timing chain with billet steel gears (seemed like a nice piece, esp. with a 9 way crank key....).. And the Holley Street dominator intake, 1" 4-hole aluminum carb spacer, Moroso Blue Max wires, Accel plugs, MSD Blaster 2 coil, Mopar Performance electronic ign conversion (Orange Box), mechanical f.p. with Holley regualtor (had to put this on), Barry Grant Speed Demon carb (rated 750 cfm with electric choke), and a 14x3 drop base air filter. This car had a most certain "idle" to it, until I idled it up some..... The previous owner installed straight pipes on it, unsure of the muff's that were on it. I had to change the factory starter out, and ran a Power Mater XS torque starter, man oh man what a change.... Anyway, I'm not going to sit here and say anything bad about anything, well, I will one thing, I hate that Carter AVS that was on there when I got it, man that thing was shot.....
And the Holley 3310 that I had on there for a little bit, and still have it... well, I found myself adjusting that thing quite some bit
. I praise the Demon b/c of I've had no problem, and have heard none, but that's another topic later.... The Mopar Cam that I installed, ran great while I had it, after I sold it however, the new owner, wiped a lobe out, dunno how, but he did. He said he installed another cam, little smaller, he said the 509 was too big for his liking?....?
The tran's that I built, with CRT's help and the folks over at dodge-charger.com when it was there, he says it hurts him b/c of how hard it shifts
, I told him I built it with performance only in mind, and that's what it is...
But anyway, as fas as cams, I say each cam is ground with an engine in mind. Some cam manufactures do look more toward certain motors like chevys, fords, ect.... As far as comp, I think they do focus more on Chevy than any others, want proof? Look at the new Thumper series lineup, right now there are only 3 grinds, but all 3 are for chevy. I like the sound bites they have of them, but still, it's chevy... Don't help me out any. Anyway, Mopar cam's, from what I've heard and seen, are old grinds, and there are better grinds out now. IMO it would be nice if they'd do some new grinds, but to each there own. The things I've heard about Crane are from a buddy of mine that runs....chevy.... Not a whole lot of Mopar in this immediate area
. There are a few around here, but nothing out in the open... Anyway, I've been thinking about a Lunati VooDoo for a 383 build for a freind, later post. But as far as the Stroker build, when I talked with Indy, they said they will install valve springs matched to the cam, hince this post. They said the SR heads should be able to handle 600 plus horse power. For a street car, in this case a '70 Duster, I've decided on a manual trans unless someone changes my mind... For a bad boy street car that want be driven a whole lot, maybe more like a weekend here and there, what would be an ideal #? To me it seems like 600 maybe a bit much, then again... You can never have too much. I've been leaning toward the fast ramp design mechanical flat tappet because you can get a close to roller cam performance with out the
required for a full roller setup. The 440/505 Stroker uses the Fast Ramp design, but it over a .600" lift, and the duration to go with it.... Big ol' cam. Anyhow, I didn't set any numbers, so cam spec's are at a hault right now, I'm just trying to figure out what everyone thinks about different cam companies, and what kind of problems they've had with them, and what pro's that they've had with them. I know CP has built god knows how many motors, and I do look to him for info, once again thanks CP. Moper has a lot of info too, and seems to have built a motor or two also, so thanks for the info so far, and keep it coming, maybe this will become a posted topic for people to look into. Hmmmm, how about this question:
How do you determine the best cam for your motor?
And no, I'm sorry to say, hoping online and coming here and posting every little and large detail about your whole car, and what you want it to do on each build doesn't count
What I'm getting at is, something we can use as a guide line to specifing a cam. There's a lot involved, but it would be nice... And cam deisgn, the break down of a cam, for those who don't know. I'll hush now.
