CAMs and stuff

[Pheonix_LJ_KID]

Some of you know i have a Pontiac Phoenix LJ with a 2.8L v6 in it..
i was wondering if some 1 here could help me find the right cam for me

My engine is carbed so no computer tuning right?
i want it to lope you know sound really cool were it can idel but not realy...

im kinda lost on what i should get and were to even get a cam for a v6

and when and if i do get a new cam i will get new bearings, hyd. lifters, pushrods, balls,aand rocker arms

and would i use new stock rocker arms and just a new cam

some 1 wana help a guy out lol
thanks

Get the Crane Cams 272 cam with Comp Magnum 1.6:1 roller tip rockers. No sense in buying new stock rocker arms when the magnum arm are under $150 for the set, are roller tip and higher ratio they come with new pivots and nuts also. The lifters will come with the cam kit and you don't really need new pushrods if your trying to same some cash.

You wont be able to change the bearings with the engine in the car. It will have to be pulled.

You will also need new valve springs, retainers and valve seals.

Hell you know what after all this shopping you should just buy the comp Cams K kit. K16-233-4 it will give you the comp cams 260H cam and all the related parts you need to support the cam. Then you just have to buy the rockers on top of that. It wont have quite the lope of the Crane cam but will perform very nicely. Just lower the idle to get more lope LOL

If your using an automatic,you may might wanna stay conservative on the duration to avoid changing to a higher stall converter. Those 2.8s are sortta doggish anyway, so you don't wanna compound the issue any further

Summit is good but don't overlook your local suppliers. I get my parts CHEAPER than the American price on Summit's site and I am buying in CDN dollars.

Your engine does not have that high of compression unless it is the HO engine. So going with a large cam like the Crane 272 will hurt performance. I would stick with the Comp 260 package. Do you know if you have the HO engine?

[Pheonix_LJ_KID]

i dont think so

[geoffinbc]

If not then you have 8.5:1 compression which will not be good with a high performance cam. You want a cam that will help build cylinder pressure.

To get significant lope at idle, you'd have to install more cam than your engine can use unless you change a lot of other things. Catch 22, I'm afraid.

I use the 272 cam and it doesn't have much lope at all. Mind you I am using it on an injected 3.4 - I have no idea if the experience with a carbbed 2.8 would be any different.

- I have no idea if the experience with a carbbed 2.8 would be any different.

That's the smartest bit of info I have read on this site since I joined! It's Refreshing to hear someone admit there not sure or just don't know...

Look kid sorry to tell you but you motor is down on luck.. your piston compression height is just too low (.020) and your valves a bit small to enjoy
a lopy cam....
Cheap fix: glass pack, advance timing 4-6* turn down the Idle to 750-800
and have fun!
Mild cost: Eldelbrock manifold, 350 or 390 Carb, with time adjustment and glass pack or Junk yard 86 or newer 2.8 - 3.1 - 3.4

Asking mom and dad for cash build: 3500, 3X00, efi, and so no and so forth, to many threads listing options we all wish we had time and money to build....umm

Start with a 85+ block if you can. Those early ones are weaksauce in the bearing department. Mine started to let go at 150k. use a F body 3.1 or 3.4 block as alternative if you want to build all out. Are you sticking with that craptacular rochester electronic carb?

[robertisaar]

didn't all of the gen2 blocks have oiling issues/downfalls compared to a gen3?
