Hey guys, I've been searching through as many old posts as I could find that were relevant to me, but still got a couple questions that I couldn't figure out from them or werent exactly pertent to my needs.

I'm looking for a set of cams for my stang, which is mostly a summer DD, rarely strip used and never sees rally.
I want a set that gives me a lumpy idle, as I see no point in getting a set that doesn't even change my idle at all.
So Im curious if there are sets that allow for stock heads/springs that will give me that lumpy idle im searching for? I will get a tune im sure as keeping the stock tune doesn't seem wise, and if i must i could get the springs swapped out.
I've heard lots of good things about HiTech cams, so would they offer a set for my needs?

I was also seeing mention of TB/Plenum swap but not sure if its a must for when doing cams? Cause I know that they will pretty much net me nothing hp wise without iternal work, from what ive researched and witnessed.

Thnx Guys!

u can get some basics vt stage 1's.......

don't expect more then 10-15rwhp off of them though.......

Ok got the Comp Xtreme Energy Stage II. They say mild to rough idle. You have to change the springs. They are going on this weekend. I will try and get a video. As for the t/b and plenum, if you do heads, it would be wise since the engine is going to breathe alot better. If you want Im selling a t/b and plenum, check my signature. PM me and we could work something out

you need to get a hold Jim@cushmanmotorsports...he sells vt cams..

[tom2000r]

take the he off off there...lol

i thought VTs werent sold anymore

they arnt.

thought so, theyre comp cams right

[zerofx150]

no Jim is the original designer of the VT cams so they are now call CMS but same cams different name

You can get a pair of cams of cams set up for exactly what you wanting with a custom grind. Tightening up the lobe seperation of the Comps would probably be the easiest way to achieve your goals.

comp xe262H Good street cam. Wont cost you low end power. gains starting at 4500 and pulling to 6000. Dynos show 48hp and about 15tq on an engine dyno with no accesories hooked up, stock manifold straight pipe. and a f.a.s.t systme managing the a/f. So on your car at the wheels probably 40hp gain.

I wouldn't look for a 40HP gain with the cams you mentioned. The 2V's don't respond to cam changes like the 3V's do.

[07stanggt]

Um actually they respond better then 3vs. I scan and post a picture of the dyno if the thread starter is interested. those numbers are on a 2v, pi heads.

The numbers will depend on other factors of course but that is with any cam he chooses.

OK, let me rephrase the:

Having installed many pairs of Comp cams on 2V motors, I know that you will not see a 40 HP gain to the wheels. You can print off any dyno sheet you want, but it would be like me advertising my cams at the extreme high end and adding a disclaimer.

AC Miller Mod Motor Cams
With these cams, our test motor made +90RWHP and almost 70 extra Ft.Lbs. of TQ.

*Your results could vary based on several factors uncontrollable to AC Miller Mod Motors..

[07stanggt]

What gains would you expect with those cams?

And what cams do you recomend and what gains could be expected.

I would expect about a 25RWHP gain with the cams in question. I would probably suggest almost the exact same cams with a tighter lobe seperation given the fact that the OP doesn't want to change valve springs or go all out, but he still wants a choppy idle. There are cams that will give you a 30-45 HP gain, but there will be some valvetrain modification required.

[07stanggt]

You would recomend almost the same cam, then we are in agreement. 25 depending on other factors could be what he gets. I specified the conditions that those gains were acheived. There is no garuntee on power gains. It doesnt change the fact that 48 has been acheived at the crank. Custom grinds for street use, isnt my thing. Not when comp alone has hundreds of tested and proven grinds to choose from but if your that good, cut him some cams.

I speak with Comp on almost a daily basis. Even they will tell you that they grind cams for the average consumer. That is, they don't grind cams for specific applications. You will always make more usable power with camshafts designed for your specific engine.

[07stanggt]

Maybe I'll give comp a call someday. Daily you speak with them? You must be moving a lot of cams or something. It sounds like your well qualified.

I guess the thread starters comment about "summer DD, rarely seeing strip action and never road raced" just kinda threw me. Sounded like an average need to me. Figured he would want a mild cam that would show some good power up top but not give up too much down low. What are the specs on the 262Hs? What seperation would you go with to enable the continued use of the stock springs but bring better power gains?

What cams you got in your 2 vavle?

By the way the cam i said, the xe262H. You dont need to change vavle springs, thats one of the reasons i recomended it. The lift is actually a tiny bit smaller then stock, im not sure what the seperation would have to do with VSR or NSR, but hey i'm just learning.

the xe262AH you would need to change vavle springs.

I don't order cams every day, but I do talk with Matt Summerfield (Tech) frequently about different profiles and what Comp is doing with some of their grinds. The seperation doesn't have anything with replacing valve springs; Lift and ramp rate has the most to do with that. Generally speaking, a tighter lobe seperation will make more power on a NA motor to a certain degree. Comp grinds their stocked cams with a 113 degree lobe seperation, so customers can use the cams with NA or FI applications. Also, tightening the lobe seperation will produce a choppier idle, which the OP was wanting. I have a pair of my custom grinds in my motor. 250/246@.050" lift- I will leave it at that. I just had a pair of cams ground for a member on the boards (98SilverStang), and he can let you know how they do after I get them put in.
