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.
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 Grady
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: Grady
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 Grady
