Now I know the Cam guide is there for reference, and I know that I can purchase a Cam Kit; however, I would like to reassure myself that I am right or wrong, or if something is highly recommended that is not mentioned in the HowTo guides or Cam guides etc.

The two particular cams we are looking at today, are the

G5x2- 232/240 .595/.608 114LSA
and
Futral Motorsports F14 232/234 .598/.598 112LSA

The G5x2 will be going into a full bolt-on, '99 Z28 w/ a LS6 Intake Manifold, 3800 stall torque converter and 3.73's.
The F14 will be going into my car which will be a 6-speed w/ 4.10's and most likely a Textralia or Z06 clutch.

Heres what we were looking to use for both
Springs: Comp 918 (would this work fine .625 lift they say)
Pushrods: Comp Cams "HiTech One Piece" Chromemoly (what length 7.350 or 7.400?)
Retainers: Stock or Titanium (see below)

Now I know there are other things needed, this is what joggles my mind a little bit. We could get the Dual spring kit for his car, but he would prefer to go w/ the Comp 918's and I could go w/ Comp Cams Conical Spring kit that works on stock retainers, but I do not know if this is recommended or to go with titanium retainers. (There's also no full details to say what this valve spring kit actually contains) It is good up to .600 lift even on aggressive cams, according to FMS but I am really unsure.

We are also curious to know as to what Timing chain to go with, will we need new lifters for these sized cams? Is it safe to use the stock rocker arms, or should we get aftermarket ones as well.

I have been reading up and have helped several friends with cam installations, but all have used different cams, different sizes, some used different heads, parts etc. Too many variables to compare to these 2 cams, particularly because they are going to be run Cam only and they are larger than most I have dealt with. The only one similar was a Head/Cam swap which we did replace the lifters and everything else.

Thanks in advance,
Adam

Well, I'm going to be doing an F13 install here in a month or so hopefully, and I'll give you a run down of what I'm going to be using, and explain why.

F13, PRC Platinums, FMS 7.400 Chrome Moly Pushrods - Using the dual springs b/c while the 918s could handle the F13 when properly setup, I don't want to risk that big of a cam with the bigger/faster lobes on a daily basis on singles. Just my preference. On a race-only setup, 918s would work, but my car is a DD. I'll be using FMS's CM pushrods, I have 7.4s.

I'll also be using an LS2 timing chain. The stock one has worked fine in my car for 75k miles, and the LS2 chain is a hell of a lot beefier. Lots of people have been running it without issues.

I am also going to replace the lifters, either with Comp OE-style replacement lifters or Mellings replacements. I've heard good things about both. My buddy just had his motor wipe out b/c his lifters went bad on an F14(had nothing to do with the cam, his car ran hard w/the cam in it), but I would definitely suggest replacing the lifters.


Personally I wouldn't suggest running single springs on either of those cams on a daily driver, but thats not because the springs can't handle it when properly setup, its because of the single point of failure. With dual springs you have a second spring to hopefully catch the valve before kissing the piston.

918's are only good to .600 lift. You need dual springs.

I went with the Dual Springs, LS6 Ported Oil Pump, Dual timing chain. I would also change the value seals. I did not change the lifters. I did change the rockers but many people use the stock ones.

Good luck.

the patriot dual kit would do nicely....and it has a very resonable price at that!!
