AJ's Rebuild - Cam

[tderrick]

Same guy... Same mild rebuild

thinking about the Crane 2031 cam. Is this a good OEM replacement.

I don't want to put in anything that will screw with the stock computer.

Sorry, Guys!! moving this thought to "Aj's Rebuild" thread....

A statement such as that
and
If you're talking about doing a NA combo

You don't have much of a chance for making any real power

For 300rwhp or above NA

Ya gotta move some air :Word:

OEM stuff just can't cut the mustard in that area
and
Without optimizing the pcm

Most combos I've seen with such a build have been closer to
250 than 300

Please don't think I'm here to be a spoiler or rain all over your parade

I am just trying to have you see what others have done which will
give you an idea of reality

Food for thought

Ever see that Big Ole Thread about making 300 with p heads

If it was easy to do it

There would not be such a thread with so many
searching for a way to make it happen

I could be wrong or forgotten the exact limit but

Tom Moss is a good guy who knows a good bit about OEM stuff

Seems like he says on his site 265 is about it when using OEM stuff

Again ... If I'm mistaken ... Someone put up the correct values

Also ... I've seen more that a few Aluminum aftermarket head based
h/c/i combos with aftermarket intakes and aftermarket (not alphabet)
cams be in the 270 to 280 range because they were trying to
tune with fuel pressure and dizzy twisting.

How much power are you expecting

Seeing as how I've tipped the 200k miles point, just having a fresh stocker would be exciting!!

I'm not looking for big #'s.... Just looking for the most bang for the buck when I do rebuild. I don't race and I don't high rev ... so, looking at some hp spec #'s, it looks like everything pulls the same at 3k revs. The stocker actually has better #'s in this range than the Hi-Po stuff. The aluminum performance heads don't take off until 4-5.5k range, Which I think I 've done
twice in my life!!!

I love the TFS kit, but is probably overkill for my driving habits... But, with a stronger build, I would probably not baby it as much either...

I'm quite torn....

any suggestions??

I mean, by the time I do some work on the E7's, I'm gonna be half way to some Twisted Wedges.... And with the TFS kit, no Intake work... No Cam matching ,,, etc. I feel like just saving up the cash so I don't have to dink with all the small stuff....

I don't understand why a combo with Aluminum heads is gonna have
a power band from 4500 to 6K

Have you ever looked at any of those dyno charts that have been
put up here

Some of em put it all over OEM iron heads at low and mid range
and certainly
On the high end .............

the OEM heads are gonna peter out much sooner :Word:

THe charts I've seen have similar numbers at low revs for almost all heads.
the HP values don't jump radically until Hi rev .... meaning Hi Flow. This is why these are called performance heads. You don't buy them to shift at 3 grand....

This is kind of what your saying anyway...

What I am saying is Aftermarket Aluminum heads from the big three of
Edel, TFS, and AFR are gonna out flow OEM Iron heads everywhere if
the combo is setup correctly
