Well i have had some parts laying around for a few months and I finally decided to start install them and get some results... I wanna see just how fast the 4.8 can go... I want to see 12's... My fiance is out of town this week so hopefully i should have the heads on and retuned by this weekend ...

My fastest time at the track is 8.58 @ 81mph (1/8th)... I plan on installing each part then go to the track to see what results come from them, maybe the dyno (that is a big maybe)... I don't care about dyno numbers, i am more interested in track times

So the parts are:
First - PRC stage 2.5 heads, milled down to 58cc, Dual spring and Ti retainers. I will be installing them with a .04 head gasket.
Second - Custom Cam from Ed Curtis @ FTI specs unknown
Third - NNBS 90mm (actually 87mm) intake and DrX harness...


So now for the pics.

Today's Progress.. All this only took about 1.5 hours, previously i had reran all the wires on my motor which makes removing the intake super easy, only like 10min... Hopefully this time i can get the wiring covering back on



PRC heads






Now a side by side pic of the new 90mm intake versus the 78mm intake. You may not be able to tell but the runners are alot longer, the intake itself is a lot bigger... From what i have read, longer runners promote more TQ... Well we will find out...

 

isnt 90 a little overkill on a 4.8? looks nice though.

 

The NNBS 4.8s come from the factory with a 90mm

 

Nice, I'm looking forward to your feedback with this swap. I just barely got my tuning problems taken care of. LOL I kinda wish I went bigger with the cam...

 

interested in the outcome...keep us posted

 

you will love the tbss intake it was night and day over my stock one but i've got more cubes but think it will help you out too should be a badass 4.8 you got going there.

 

I think you ought to sand and paint that intake. i think it would look pretty sweet

 

hey thats my intake lol. Looks like fun corey.

 

Thanks colton, yep i decided to install my crap instead of selling it...

 

Yeah i saw it in your cam thread. I dont blame you, maybe it will give you some more motivation as well as results. Im interested in the intake results.
