VT, Crower, or COMP

TheBusher · July 30th, 2007, 04:44 PM

I'm looking at getting a mild set of cams for my 04 GT and was wondering peoples opinions on the better brand (by better I mean most power & reliability). I want the most aggressive cam I can get but I don't want to have to get my car dyno tuned, but I will replace my springs if need be.

04GTAMPA · July 30th, 2007, 05:00 PM

crower.

Nate's4.6 · July 30th, 2007, 05:09 PM

Anyone???

02steedagt · July 30th, 2007, 07:35 PM

comp 262.... or if you have a diablo or sct tuner, you could probably get away with the 270's, but be careful with that. i know that the 262's can run on the stock tune... and Comp Cams makes a GREAT product.

TheBusher · July 30th, 2007, 07:46 PM

So maybe a 270, but anything less will work? So what is more dangerous about running the 270, no dyno tuning or running stock springs?

MustangMatt96GT · July 30th, 2007, 08:43 PM

I say running stock springs is worse, but the dyno is needed for them too! I personally am really likeing the Crowers, but I will be going with this cam for my top end rebuild!

Cams

TheBusher · July 30th, 2007, 08:55 PM

I kinda thought it would be worse on the springs. I want to get a 270 comp or a 62801-2 crower, I will replace the springs, get 3.73s & an SCT tuner (I'm hoping the tuner will suffice until I can afford the dyno tune).

If anybody thinks that the above is a poor choice... as in... it could kill my car... PLEASE let me know before I make the purchase.

acmillr · July 30th, 2007, 08:59 PM

Do not run comp 270 cams with stock pistons unless you want problems. I have 8 pistons with half moons right now. Comp uses advanced intake timing to make power and you need valve reliefs cut into your pistons to make them work. However, they do make great power.

zerofx150 · July 30th, 2007, 11:12 PM

so whats the lift on the stock cams, and if the comp 270s are bad why doesn't comp inform people that they need this?

MustangMatt96GT · July 30th, 2007, 11:32 PM

If the comp cams are degreed, I dont think you will have problems, but I could be wrong!

And Busher! When you do this if you need some help or just want a second pair of hands I am always wanting to work on these stangs!

matrixpuba · July 31st, 2007, 02:31 AM

im running comp 262 cams in mine and have no complaints.

acmillr · July 31st, 2007, 08:39 AM

The 262's don't have as much advance on the intake timing. If you degree the 270's (retard the timing) to be able to work, you will lose the increased HP these cams produce. Just run them- I didn't listen either, and I found out the hard way. Comp doesn't tell you about this because they would not sell as many cams.

Here is a quote from another source:

"Comp Cams Stage 2 Billet camshafts 99-04
Our Favorite, awesome sounding idle, great power increase, raised redline, computer tuning recommmended for peak performance but not required. 3.55+ gears recommended, Valve springs required, must use notched pistons for valve clearance."

I had no complaints either- until I opened my engine. You couldn't even hear the PTV contact noise.

StangAddiction · July 31st, 2007, 09:42 AM

I recommend Comp cams... Dont hold me to this because im not 100% sure, but i've heard some bad things about crower cams. I've heard from quite a few people that they sometimes do sloppy work in the grinding of their cams. Again, this is just what i've heard, but i'd recommend you do some research before choosing. Just a tip.

The XE270AH cams are pretty good cams for a street car though. but they'll requite a tune. The XE262AH might not although...im not sure.

bluestang96 · July 31st, 2007, 10:06 AM

The comp 270s will work with flat top pistons if degreed properly. The 4* advance that comp cams grinds in is no defect and is there to make the cam more street friendly as it lowers the powerband in the rpm range. If
these cams are not degreed properly you have a good chance of having ptv problems. Take into account that stock cam gears can be almost 10* off from the factory and the grind advance... well you get the idea. But this goes for any aftermarket cam install...degree them. The 262 will probably be your best choice for the street and makes similar power compared to the 270 but in a more useable rpm range for a street car. The car really should be dyno tuned to get your A/F dead on and also get the most out of the cams, if your already 600 dollars in the hole you might as well shell out a little more to get the most out of your cams.

Yes. Buy those and you will have two extra cams.

Seriously, those are for the 4V motor.
