where u get ur custom short runner?Yeah, I have and SWEET2KSTANG has done a set for Doc8824. I ghighly suggestion some serious massaging of the intake. I notice the biggest gains when I was running Comp Stage 1's, A custom short runner intake, and set of PHP ported heads. Although I don't remember what kind of numbers I was pushing back then N/A I do remember making 570/611 on a 150 pill.
i meant with the 4v termi heads they are already pretty efficient so port work doesnt do a whole lot unless you plan on flowing some substantial air,in my opinion the cost of porting (unless you already have your heads off for whatever reason)isnt worth the gains,just my $.02:blahhuh? there is nice gains n/a if done right.
