.590 cam (install straight or advance?)

[Sweet5ltr]

I think you're gonna find it'll run fine. You sound like me. You just wanna have some fun.

pretty much, it is just a turkey shoot knowing if you should advance or retard a camshaft from the get go unless you run the car on the dyno or due extensive testing at the drag strip. It's all for fun, I don't like making small issues soo serious that your own enjoyment is taken out of it. My dad always says, "just drive it."

If I had to choose on or the other, without a degree wheel I would advance it 4*. That cam has so much duration, you're gonna be hard pressed to ever cut back the upper end HP much. Remember when you advance one, you add bottom end torque and take away from the top....BUT what's taken away from the top is nowhere the amount that's added on the bottom. Conversely, when you retard one, you add to the top and take away from the bottom, but what's taken away is nowhere near what's gained on top. With that much duration, it's GONNA pull on the top end no matter what.

Maybe I'm stupid. But I don't understand why someone who would build an engine from scratch would NOT invest in a good cam degreeing kit, rather than printing out one on a hunk of paper stickin it on carboard and runnin the risk of getting it out of place. Just makes no sense to me....and I'm a broke *** mofo. But I scraped up the hun the get the Comp Cams degree kit. I already had one, but I wanted the Comp kit because my dial indicator had seen better days being from the 1940s. I mean, a degree kit is a tool. Tools are what separates us from the beasts.

I guess maybe you don't understand...... But that's OK, those who can appreciate the drawing will no how to utilize it best. I'm certainly not going to force anyone to take advantage of a perfectly good FREE degree wheel.
I have a dial indicator and mag base,,, so it makes PERFECT sense to go this route!
To each there own I guess,,,,,,:argue:

Sorry dude....I wasn't trying to insult you or anybody. I dndn't mean it like all that. To me, it's kinda like....."Lemmie go download a picture of a wrench and see if I can make it work." It's a tool. A basic engine building tool everybody oughtta have if they are ever gonna assemble an engine. I mean, you gotta have a dial indicator, right? You caint use a paper one of them. ...I know, somebody on here somewhere will say you can. lol

But like I said, sorry if you took it as an insult. I know you were trying to help, and it IS a help. I know people who have used the thing and made it work. I'm all about savin a buck. I guess though bein a mechanic all my life, I just don't cut corners on tools.

Well, I'm not sure whos .590 lift cam you have but Ma Mopar says on the purple shafts the center line on that solid lifter cam is 106 and should be installed at 104 using a degree wheel. That info is in the mopar engines, 9th edition and the info does work. good luck with your build.

Hi 5 ltr, I also am running a 451 in a 69 RR. I'm using the 509 cam and 12.5 to 1 C/R. I installed it straight up, and it has good bottom end, pulls like crazy about 2800 RPM and up! Did you say there is a big gain from the .509 to the .590 lift cam? I am totally happy with this engine and would recommend it to anyone. 906 heads, mild port job. Using a Holley 700 dbl pumper atop a Holley street Dominator intake. Stock HP ex manifolds, stock ex system all the way to the oval ex pipe tips. Gonna take it to the track in a few weeks to see how it will E T in the 1/4 mile. Just put in a 3.91 Sure grip unit, and even with 16' tires will still screech awhile when the 727 hits 2nd gear!
