well i just purchased a set of Comp Cams XE262ah cams for my 4.6L 2V 2003 GT. the reason behind me purchasing this set of cams was a good price and also i have been told since comp came out with these cams that these were the only set that would not require pistons to be fly-cut.

so now after reading numerous posts on www.corral.net i hear of people saying there 99+ GT has either the Comp XE270's or the Comp XE274's and thy have NO PTV clearance problems because they had there cams degreed

WTF DOES THAT MEAN!!!!

im still pretty dumb when it comes to camshafts, i know how they work and all that great stuff, but as for lift/ duration @.050 and LSA, you might as well be speaking Arabic.....

basically what does "degreeing" the cams mean? and if this is possible does anyone want to buy a set of comp cam XE262's???

also how long im a looking at for down time on my car for install along with a rough estimate???

 

they should be able to be installed in a day...ill pm you a price after i talk to jeff

Many of the sets of 270s had a ~5 degree advance ground in and many people had PTV contact with the bigger intake valves. If they are installed slightly retarded, this can be avoided.

The install is pretty straightforward. Are you using Comp springs? Also those 262s do make good power so you might consider using them.

the problem with the 270,s and up is the duration on them so you must degree them to make sure the are set a zero or they will hit.

 

yes, i am going to be using the comp beehive springs with stock heads and valves.

 

i kinda figured it wouldnt take too long. i didnt know if the heads had to be taken off the block or not to install them properly.

 

any price yet Chad? might have a set of P&P PI heads to make it a little easier.

do the heads have to come out of the car for the cams to be installed?

 

Nope!
