So I have been reading all of the threads related to H/P outputs on N/A aspirated 4.6's and it has caught my interest. Let me point out a few things first; Yes I know you will get better results significantly cheaper with FI or NOS. Yes I know that the DOHC is a much better platform to go with, and YES I realize that you will never get the #'s of a 5.0 or LS1... So with all that taken care of, what would be the best route to go if you were to build a motor with the intention of always keeping it N/A? I have been looking at short blocks and it seems that the more I look, the more questions I come away with instead of answers.
With my tax return coming this seems like a fun project as I can put the motor on a stand and slowly build it as the funds allow.
So here is where I am at: I am kind of leaning towards the MPH street/strip short block $3,480.00 . I want to stay away from strokers and it is bored .20 over so that would yield a few extra ci, without sacrificing to much durability. First question, you can get it with Manley or Eagle rods, whats the diference? Which are better? Next I am thinking that you want a pretty high compression engine like maybe 11.5:1 and still be able to use pump gas, so piston selection comes into the picture? Is that too much compression, or could you even go higher?
Now comes heads/cams, For the heads I am leaning towards the Steen Racing Stage II Porting/Polishing Package $1,649 and for the cams I am thinking of Stage 1 Comp Cams $549.00. I read on another mustang forum of a guy who was unhappy with the stage II's because of the minimal HP gains over the stage I's and the subsequent loss of his low end...
As far as intake manifolds are concerned I think that oem plastic ones would probably be the best bet because I AM GOING to start doing this which means that I have to try and keep my cost's down. I figure this would be a good project and I like the idea of having another motor in the garge just in case something happens to the one I have in my car right now.
So you take that motor with all of my existing boltons eg LT's Mid Pipe, Tb/Plenum ect... and I think you could have a pretty Bad A$$ car. What do you guys think? These are all pretty rough plans, I am wanting input on what would be the best overall set up with cost being in the equation... It would be nice if you guys could not only post in your opinion what would be the best setup, but where to buy it the cheapest... The cost of this setup is about $5700 so obviouly if there would be a way of doing for less that would be ideal.
Thanks in Advance all of you here at :SNSign:
