Anyone? UD Harold, whats your opinions on this cam? Thanks.
I'm not using it, but I can tell you that it'll be a choppy idle with only 106LSA and have poor vacuum. It's a big cam, so I assume you've got heads flowing upwards of 285cfm. Typically when you shop on the bottom of the cam page, you get a totally unstreetable cam. Will kick butt in a 4000+ stall, 4.11+ gear strip car. Will also be mildly brutal on valve springs.

Umm, Anthony,,
Hate to be picky but,,, I think even Harold is going to have a little trouble with this one without some more info,,,
It would help to know if you have a 265 or a 421 or something in between along with compression, intake, heads, carb, gear, weight, intended use,,,,,
It will work great for what it was intended for.

Your right Mike. I don`t have a motor built yet, I was just wondering if anyone was running it.Wolfplace said:=

I`m thinking about building a 11 to 1 383 with either AFR or Dart Iron Eagle heads. Thats about as far as I got. My buddy gave me a 350 4 bolt shortblock, the car has a TH350 tranny, I`ve got 4.56 gears in a box. I already have 1 3/4" headers and a complete MSD set up in the car now. I did`nt think it was too much cam since it only has a few degrees more duration than my old solid cam but I`ve never run a roller and I thought it would be a good step up.
Thanks for the replies and if you got any other input lets hear it.

Well now,,,, that don't sound too bad,, should be a raspy little devil on a 106.
I kinda like it with those gears & compression especially with a good head.
Should make good power to about 7000-7200 in a 383 with say a 210 head & a Super Vic.
Let me know if I can help you with the heads or rotating stuff when you decide.

Thanks Mike. I was actually planning on buying the crank and rods through you and if I decide to go with the AFR`s I`ll get them from you as well. I had a set of AFR 210 heads done before and the guy who ported them got mid 280`s cfm using 28". I had to sell them before I got to use them. As far as the intake, I like the GM "bowtie" intake. I had one ported to match the 210`s and the guy really liked the set up. I`ve got a few questions about the 210`s but I`ll wait untill I have the cash. Tax time is just around the corner. Thanks again.
oh yeah, any guess on how much hp it would make?

Anthony,
The Lunati 50103 is one of their Legacy cams, dating back to the 1970s. I only know that I used to compete against it, and that the people at Lunati like it. It would be the type of cam a 11:1 383 with some 210 AFRs would like. It would definitely need a 3500 SS converter, and probably a 4.10, although a 3.90 might work just fine.
I would talk to Steve at Lunati, 662-892-1526, for more details. I have never sold one in my life.

Thanks Harold. What would you recomend instead of the 50103? What were you using to compete with it? Thanks again.
Anthony,
What I have used for years is now called the Lunati 501C1LUN and the Lunati 501C2LUN. They are the same cam, but on different LSAs. The C1 is on a 106 LSA, the C2 on a 109 LSA. The 501C2 can spin rims on the street, and needs screws in the rims. What does that tell you about the 106 LSA? Hooked up, the C2 will run low 11s, high 10s in a 3300-3400 lb car. I even had a 455 OLds at 3670 lbs running 10.90s at a BOP National even, launching at 1200 to avoid roasting his tires.....
I have some AFRs, and the last cam ground at UltraDyne was the same as the 501C2...
It will need a good fuel system, as I don't see how you can avoid 525-550 BHP. In a 12.5:1 383 with a good port job you're looking at over 600 BHP, with the 501C1LUN.

Thanks for the specs. I don`t have a new catalog, I was looking at the online catalog and could`nt find either cam. They look better than what I was looking at. Thanks again to all who offered input.Wainman said:
