So how hard is it going to be to get 300 rwhp out of my 4.8 w/108k miles

as far as mods go now i have

Hamm mids
K&N 77 series intake
W4Me tune
stock 3:73s
vette servo
tb bypass (lots o power )
Taylor plug wires
2.5 single exhaust imco extreme 12" dumped at axle

future mods are efans and ported TB

 

i think a healthy cam and you would be close. i would be more worried about getting more torque...since that is what our 4.8s lack

 

A decent cam and good tune will get you there.

 

I have a tr224, LTs, K&N CAI, dyno tune, and I made 300 on the dyno....

Talk to 01 Thunder. He's kept his 4.8 na and done well with it.

 

I had a 4.8 for a long time and had alot of fun with it! How much would you like to spend? You can turbo a 4.8 and put a cam in to see some really good numbers. All depends on what you have to spend!

 

I don't think I want to turbo it. I'm thinking about getting a TR220, and a stall and having some other bolt ons done. Pullys and efans, Right now the W4M is doing fine, although I deffinitly need to send it in for a retune since the headers were put on and I deleted the A.I.R. Just waiting to port my Tb so I dont turn right around and do it all over a week later. There are a couple places close here that can do a tune, so thats not a problem. How hard was it to tune your 224, I mean this is still my DD.

 

I drive mine everyday, and it gets lots of attention....
pulls like a raped ape, above 3000....

 

thats cool, I think that I will go with a 224 then.

 

hell yeah it does!!
