Hi I have a 2002 f 150 single cab flareside 2wd lowered 2/4 which im planning to turn into a fun ride.
It currently has long tube headers, edge cts with gryphon custom tunes,dual electric fans and 4.10s with 28s.

The 5.4 has 81k miles but its in perfect condition. (I made a mistake in my original post, i have 130k "Km" on my truck)
I wanted more power of it without supercharging it.
I also want to buy a forged rotating assembly for it, but since its running strong i want to wait for it to start knocking at least...

So i wanted to start by adding:
1.trickflow heads
2. custom comp cams similar to the xe262h with maybe a better lift using the advantage of the trickflow heads ( aprox 1500-5500 rpm range)
Better converter with a 1500 stall at least

As you can see this will up my cr to 10:1, I am on 4.10 on a lowered 2wd with 28 tires, so :
1. will i loose that much low end tq to feel it?
2. how much power can i expect here?
3. will my stock bottom end hold a while, atleast without thorwing a rod and destroying everything?
4. Other recommended cams to look at, or maybe keep the stock pi ones?
5. Should i keep the stock pi intake or will i see gains on going to the hps one as i see is the only better option?
6. besides head gaskets and head bolts, what else should I change ? expendable or gasket wise?
7. Do i need bigger injectors and MAF?


In a year or so, I will defenitivly upgrade my bottom end, asi i said earlier, I just want to use up mine a bit more since its running strong and then maybe run a blower or higher compresion, depending on the results i get,

any opinions are welcome and thanx
Joe

 

IMHO, the cam grind you have identified is really pretty mild. Personally, I would not use any time to install it unless i needed to replace my existing cams for whatever reason and without a higher performing cam, you are really not going to see that great of a benefit ($1K) in power from any aftermarket heads- especially in that rpm band...its really low, basic street type performance range.

if you live near any major city there are excellent tuning specialists with dynos who for the same price will tune your vehicle taking into consideration your specific needs including environmental conditions, for your specific vehicle, probably gaining every bit of power that you would see from that cam .

With regards to cam mfg...
Comp has by appearance - seems to be a company that has experience more cam lobe failures than most and places the blame on the low ZDDP in the oils. Is it a factor yes, but I highly suspect that they are also using Chinese cam billets & they do not include Parkerizing their cams (Parkerizing is the final step and a crucial step to help break the cam in- a heated acid bath that microscopically etches the metal surface and adds a very thin layer of graphite coating which allows the cam lube to hang onto and penetrate into the cam surface during cam break in) unless you specifically request and pay additional money for it.

Considering the cam has such critical importance to the engines performance and life, to me it makes sense to use a cam grinder who will talk with you directly- even modify the cam grind to fit your needs even better and to address the possibility of cam lobe failure with the new oils. With regards to price...the difference is nil- especially considering its cheap insurance to know exactly who is machining such a critical part for your engine. And remember, advertized lift/duration/lobe separation is just that- advertized and not the specific grind including ramp profile that is used on the cam.

That is why I highly recommend Iskenderian & Crower...both are family owned, been grinding cams for decades, and both will even re-grind your oem cam if possible- saving you even more $, In the 1970/80's Crower even had a grind that would allow you to run up to 11:1 CR and not exceed 150 psi cylinder pressure....meaning for the pre-mod engines, you could run on pump gas without any pinging! Isky still checks/tests every valve spring befor it leaves the shop! Call them direct, they love to talk and identify what is possible and reality!

As you are probably aware, many of the cam mfgs in the past few years either sold, closed their operations to re-open elsewhere (typically with new staff) or .......

In addition to Isky & Crower, I use to very highly recommend....
Sig Erson & Crane...

Both became part of corporate entities, eventually leading to periodic quality issues and closing their doors- I think Crane re-opened, but with a different staff. Typically the staff is very, very young and well- requires a learning curve and in many cases, the acual cam grinding is outsourced, sometimes overseas- that just doesn't make me comfortable in ANY WAY!

If you do a search on the net, Harvey Crane has posted a little summary of the history of the people who made the cams at Crane, his opinion of what happened and the eventual outcome of several of the staff.

Given the criticality of the component- IMHO, I don't like speaking to a catalog parts sale person- they really don't know any more about the cam than what they are reading- companies like Summit, while their bulk purchase agreements are great for price, when it comes to making an engine breathe, there are so many variable including elevation, humidity, fuel blends/available octane, most cam mfgs will vary a "core grind pattern" to match the external impactors in addition to the internal impactors- which today IMHO makes the different between and engine that runs well, to one that just seems to run a little bit better, smoother and gets better mileage than expected.

 

Thanx for the cam advise, I have had trouble with comp cams in the past with older engines, ive just never modified a modular so was browsing in the popular, i will call isky for a custom cam. Ive also heard of other cusom manufactureres but as i said i have no experience in making these engines breathe.

Any opinions tips on my other questions? Ive been readinga lot on many builds, but nothing specific on what im planning on doing and i know its better to have as much opinions nad advices on anything that im not experienced on so i dont have a reck then,

Thanx Joe

 

I have been running the Comp 262's for 5? years along with SVO ported heads and no problems with 9-13 psi boost.
If you plan on no boost, I would look for a little more cam.

 

What static compression are you running wolf? Whats your peak power rpm? Im a dynoguesser and gonig to the xe270ah (next comp cam) would bring my rpm range to 6500 rpm with the tf heads...

On a side note, On the original post I stated my truck as having 130k miles hehe i ment 130k kilometers = 81 k miles...
