There is a great list in Jeremy's cam tech thread with a bunch of different specs from all different cams

That should be stickied as well as the fuel injector one.

What are Hot Rods?

Is there a list anywhere of the specs on the popular cams?

I suppose I could make one... Hmm




*edit* Look what I found (Ill add the specs you posted as well)

Anyone know the specs on any of the other common cams? Ill post what I can find. Any requests?

[S197gt07]

It doesn't shoot a hole in any theory, since those specs for the 205's are wrong.

The LSA is 116.5, also, no way in hell the stage 1's are a 100 LSA, thats super wrong too.

Davenow. Theres is alot of wrong data in your post, 109/110 lsa is less than idea for forced induction. See the cam tech thread for a list of specs.

I got the comp cams info off comps web site.

I know I got that one with the 116.5 wrong. I dont know where I got that number, I was looking at the page, I saw the number, and it just didnt make it to my fingers on my keyboard.



As for the less than ideal.

I am a bit tired of people pointing that out, when I very clearly say it. I am not like coming at you specifically with that (so please dont take it that way) , I'm just saying its a little disheartening when I say something, then someone comes and says it to me like I dont know what I am talking about because I dont know it. When I just said it They arent giving me some new info lol. I have always said an NA cam isnt IDEAL for a blower, however, and this is what I have been saying, it can, and does work, provided you dont go nuts on the NA cam.


That said, I REALLY dont want to be putting bad data out there. So other than the 205s, which I fixed now, what else is wrong? So that I can go fix it

Please note the NA cams with 115.5 and 116 LSA.

The reason I point that out is that LSA seems to be the hot-button when people talk about NA vs Blower grinds.

I know one isnt ideal for both applications. However, what I am saying is that both CAN work, with both applications, provided you arent going to a more aggressive cam (more aggressive than mild)

115 lsa for the 127055 cams. I can see what Dave did, he typed the centerline instead of lsa.

Comp has a nice pdf on 3v cams here: http://www.compcams.com/3valve/COMP5-124.pdf

What I saw off the top of my head I highlighted in red.


Na cams work great with blowers the stock cams are na. Whe the lsa is too small/tighter it does not work great with boost (cams in the 109-110 range) for many reasons but mainly it restricts flow due to the increase in time both valves are closed. Not a big deal on a na car but with boost its very evident. The only gain here is up top/peak due to increased lift, but power under the curve is affected. 113-116 is more acceptable for a boosted car.

Hello , I have Anderson Motorsports cams for FI .. The cam # is AF-F43L and the specs are 215/232 @ .050 , advertised duration is 257/274,
timing events -5/35.5 intake 52/0 exhaust lobe lift is .245/.245 gross lift is .495/.495 with a 112 LS. This cam can use stock valve springs,but needs phaser lockouts.

What do you think about Hot Rods VS Motha Thumpers power wise, on an NA car?


I love my Hot Rods, but I am always looking to change things around and if the MTs will pick up enough power, then I may consider it.

The other question is how are MTs going to be driveability wise with an Automatic on 4.10s but stock converter? I know the 4.10s will help, but with the stock converter I am concerned about driveability...

I dont even know if I want to bother with it. I am happy with the HRs, but the MTs seem to lope a little harder, and if they make a little more power.....

As for the stuff you highlighted, some of it I cut/pasted from other threads, like the 4.5 thing and such. I dont remember if I looked the specs on that other cam up or copied/pasted.
