Cams

[loud2004marquis]

If you change your cams, do you need to get a tune?

[MMBLUE]

Simple answer: YES!:banana2:

[J-MAN]

Yes, but put the $ towards the Trilogy fund!

[SC Cheesehead]

Simple answer: YES!:banana2:

Uhhhh, what he said.... ;)

[dohc324ci]

Save your $$$ for a Supercharger.

[Spectragod]

Get the cams AND a Trilogy...

Save the money, don't buy cams, just go with the Trilogy...

My dyno sheet says different, get the cams, pricey, but I pick up quite a bit off of them.

You running cams and a blower? I did not know that!

Inquiring minds want to know.

Most recent dyno sheet.....

You can almost see that, 521 horse, 526 torque.

Just had a "small" tune up done.:D

[LANDY]

Just had a "small" tune up done.:D so 50rwhp gain on a cams swap, not too shabby.

A "smidge" more than that.:D

[Cobra25]

My dyno sheet says different, get the cams, pricey, but I pick up quite a bit off of them.I Have to agree also, When I Rebuilt my motor a few months ago I had Stage 3 Comp cams put in. It sounds great. It made a nice difference but it can be hard too tune correctly dependant on the cams you put in . Take your time and read up on it more before you choose the cams you want to install .

[MOTOWN]

Im considering crower stage 3, or comp cams stage 3 for my build, i love the way they make power, and sound thru out the power band!

Or a really loose converter... That is the direction I went with the comp cams stage 3's

[Cobra25]

Or a really loose converter... That is the direction I went with the comp cams stage 3's BY loose you mean a Higher stall correct ? I have a BC Auto Stage 3 * 3200 stall TQ in mine. For me it works fine.

Yeah im minutes from Lidio!:banana2:

[Cobra25]

Yeah im minutes from Lidio!:banana2:Well all I'll say about that is hes one of the Best !

[loud2004marquis]

Lidio's AWESOME!

[Spectragod]

Why weren't you there to meet me there last week? I was the lone Marauder in a shop chocked full of Mustangs.:alone:

[TooManyFords]

Yes, loose = higher stall. Mine stalls at 5000.

[Pops]

yes, loose = higher stall. Mine stalls at 5000.

:d :d :d :d :d

[SC Cheesehead]

5K stall! :eek:

Good thing you don't live in San Francisco...

I had no idea you were there, i would have come over, and checked out your ride! let me know next time your there:rolleyes:

see ive been wondering how a SC would have a positive effect on cams with more air flow.

[na svt]

Any cams with more tha 226 degrees duration and a wider LSA than 111 will not work in a heavy, automatic trans car. Both the Comp and Crower stg 3s are a bad choice for a marauder...for a few reasons. A maruder needs a boost in mid range power and tq and the 234 degree comps will kill both. The Crowers are a little better, but not great. It is possible to make them work but the driveability will suffer (very loose converter, lots of gear).

You can get cams that will make more usable power and use the stock valve springs saving you a lot of cash.

To get a rough idle all you have to do is tighten the LSA a little and you'll have the best of both worlds, power and sound.

[Spectragod]

I wound up using Crower stage II cams, part # 62822-4. With a twin screw, they are a good choice, driveability is good, mid range is good, and..... I am running 3.55's. Then again, this is not a DD, and I don't think it would be a good choice for that application.

[FordNut]

Mine are Comps.

222/224 duration, .475/.450 lift, 114 LSA

Sounds and drives good, no lope though. I'd kind of like a bit more, maybe 234/240 duration

Already have the Trilogy, and now getting cams. Good to hear they are a boost to my boost!

The next step would be a part # 106360 ( Stage 2 ) which would most likely be the best cams to up grade too in our cars. I had part # 106460 put in ( Stage 3 ) when I had my motor rebuilt only because the ( Stage 2) #106360 was out of stock at the time & I had no time line to when they would be avalible. . Their are some drive issues with the ( stage 3 cams ) & unless you have a really great tuner I wouldn't advise most people to use them. Most of my drive issues have been resolved but I still have to do another up grade to my fuel system. Then I'll have it fine tuned. Comp cams web site has excellent info on these cams , just do a search on the part #'s.

well i have two marauder buddys with stage 3 crowers (tuned by lidio) and they run great!, both have 4:10s not sure what stall speed, upgraged feul lins ,pumps, and sumped, one is supercharged, and the other is n/a, this is what attracted me to the crowers, they do say that the car will need to be tuned after the cam swap

I kind of figured a 106100 (226/222, .424/.425) would be first step above stock (185/195, .398/.398).

I do have 106260 now. I don't know about stages... How about we just use part# and specs? What I'm thinking about would maybe be a stage 2.5 based on the stage# quoted above.

Intake would be like a 106400 (234/232), exhaust like a 106460 (238/240).

This is based on a well respected custom cam maker's suggestions for my particular setup.

This is based on a well respected custom cam maker's suggestions for my particular setup. I didn't know about the 106100 cams, but the site states that no computer tuning is necessary or any thing else & being I don't know the spec's of our factory cams I can't comment. The site states that the #106260, #106360 & the #106460 are : Supercharged & Nitrous Series cams. Theirs no listing of that on the #106100 cams so I take it that's for N/A cars . On the #106260 their is a RPM range listed 1200 to 5800 , The #106360 Has a RPM range of 1500 to 6000 & the 106460 has a RPM range of 2000 to 6400 .The higher the RPM range the higher TQ stall you need . I'm no expert on this I only know what I've learned so far & what their site states. I think I understand what your saying about maybe a (2.5 stage cam Intake 106400 - Exhaust 106460 ) but I don't know of anything like that out their.

Cool, I've just always had a thing about cams being referred to in "stages". Minor changes can put a set of cams in-between a specific "stage", so there are technically an infinite number of stages possible. And sometimes you find that one brand's stage 2 is hotter than another brand's stage 3. Check out Comp vs Crower vs ModMax and there is a wide variation in their mild, intermediate, and hot cam specs when you look at the different brands. My Dad was an old-school drag racer and he always taught me that cam stages have little to no meaning, what counts is lift, duration, overlap.

I had this conversation with Lidio when he was doing mine, he basically put it like this, the stage 3 cams are $300 more and don't give you that much more for the $$$, hence, I went with the stage 2 cams that he recommended. Then again, I have 3.55's, so maybe that was the push towards what I got :confused: ?????

Are you happy with the 3:55s, or are you going to try 4:10s?

[Spectragod]

No real need for the 4.10's, the TS makes up for it, + the extra 100ft lb's I picked up after going to Lidio's this last time.:burnout:
