Comp 127400 cams

[BruceH]

Sold.

$450. I've had these a few months shy of two years. They are in very good condition. They were always properly lubed when installed. The cams specs are found here: http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=979&sb=0

They require springs and phaser mods. I can share my tune data with your tuner so the driveability will be spot on the first time you drive with them installed.

112 lsa with 102 intake center line. 256/267 intake/exhaust duration. 221/228 intake/exhaust duration at .050". Gross lift is .523/.538 intake/exhaust.

will these work as blower cams at all

These are designed for n/a. I've used them with a Paxton and Procharger. The blower version of this cam is the 127450. The main difference is 1 more degree of lobe separation and a little more exhaust duration. These have 112 and the 450 have 113 lobe separation angle.

Here are the specs to compare:



This is what they sound like at 800 rpm. Stock cats, GTA mufflers.

Bump. I used comp 26113 springs with these cams. They work well with phaser limiters. I'm still on the original phasers that came with my car over 5 years ago. Many of the spring and phaser required cams don't play well with phasers and usually end up locked out.

Here's some previous discussions on these cams. These threads are what influenced me to buy them.

Edit: Did some more comparison. Apparently Livernois likes the durations used in 127400 cams. Their stage 2 blower cams are the same except they have a 113 lsa vs 112 for the 127400. They also use the same numbers for their turbo cam except with a 114 lsa.

Bringing the price down again. $425 shipped. It's a real nice set of cams that can run on 26113 springs.

Very interested, Please pM details on what else would be required to run these on my 09GT.

PM sent.

You will need upgraded valve springs, maybe spring retainers depending on which springs, and either phaser lockouts or limiters.

I'd go with the livernois 20 degree limiters, comp 26113 springs, and comp retainers. You will also need your tune adjusted.

The cheapest option would be lockouts and Trick Flow springs that reuse the stock retainers.

Here's one of the cam cards for anyone who wants to see it.

Bump. They are in very good condition.

Still for sale. I'd be interested in motor parts and wheels in trade. Specifically 3.700" big bore pistons, head gaskets for the same, Innovators west 6 rib stock size balancer, ATI balancer set up for a procharger, connecting rods, and probably other things too.

How much power should you expect to get out of these with stock heads?

How much power should you expect to get out of these with stock heads?

That's a hard question to answer and I don't have the answer. These cams extend the power to higher rpms. The springs required for these cams also allow you to rev higher. I have gone as high as 7300 without issue.

The more breathing mods you have the more power you will get. Long tube headers would help significantly.

I ran these with stock heads, stock cats, frpp manifold, and higher compression while na. My motor made 337/299rwhp/tq on 92 pump. I'd imagine that long tubes and an o/r pipe would of added to that. I also think that the frpp intake manifold took power away, it reduced torque for certain.

Almost one year later the same motor with frpp cnc heads made 337/337 on the same dyno. I can only speculate at what it would of made with long tubes and the stock intake manifold. I think 365+ would of been possible (maybe I should go back to na and find out, lol). I also didn't have the cam retard dialed in at that point. I was able to get 5% more #min of airflow after experimenting with the cam retard. I never got it on the dyno to see what the additional airflow did to the numbers.

These cams are meant to be part of a mod package rather than the only mod imo. This makes it pretty hard to give an expected number.

I have attached the comp cams 3v info pdf. They test a few of their cams and give more info about them in the brochoure.

When you say stock intake manifold, do you mean with or without the butterflies deleted?

I have long tubes, and the rest of the exhaust performed, so breathing should be pretty good. No head mods though.

Is the price negotiable or are you firm?

I'm assuming cmcv delete on the stock one. The frpp manifold would be what I'm comparing it to.

The price is firm. It's a good price. I'm certain that someone will see the value in it vs paying full price. I just have to be patient and wait for the person who wants 127400 cams instead of the one who just wants cams and doesn't care what the profile is and long as the price is right.

Wow, that's a cheap shot.

Buying used is always a balance of saving money versus giving up warranty and support. I have no interest in having cams that do not add the most useable power for the cost/effort involved,

FWIW I think Bruce was just stating true facts not throwing cheap shots

 

[jmauld]

His responses have been very helpful so far, so hopefully I just misunderstood.

Not really. If it's a cheap shot then I'm aiming it at myself because the first cams I bought were 127300 and I bought them because they were $325 + shipping from horsepower1 on ebay. They weren't exactly what I wanted but they were close. As time went on I ponied up the money for the cams I really wanted which were the 127400 I now have for sale.

I realize that there are buyers who will always try to get a better price. I think of it as the pawn star syndrome. I have these priced at a little over half the new price with shipping included. I think that's a very good price. If you don't that's just the way it is, no hard feelings. You will never have to guess how I feel about anything. I'm pretty straight forward and I don't play games.

I think this is a damn good deal.But it will take a certain buyer who wants and understands what these cams are for.I am interested in them,just not interested in paying for the springs and retainers to be installed on top of the cams.If I had more cash I would have bought them already.
