Got 4-5000 to spend tops.

Keep the 200,000 mile 4.8(doesnt smoke or leak a drop)
cam it(which one)
100 shot of nitrous (wet)
new transmission with higher stall and lower gears in rear end

or
lower mileage 5.3
cammed(which one)
nitrous
new trans with higher stall and lower gears in rear.

Don't want to go 6.0L for budget reasons, unless I can find one under $1000. Tons of 5.3s for sale between $5-700.

I need this thing to drive daily, behave decent in traffic from time to time, and not overheat in traffic. I live in the country so my daily drive doesn't involve much stop and go, other than the line dropping off my son at school. When I do drive in the city, the traffic isn't usually terrible around here. My goal is to have a daily driver that will run at least 13s at the track and on the street without the nitrous. Currently running mid 14s with the 4.8 with minimal mods so I don't think that goal will be hard to achieve. I want this thing to pull hard off the line when I hammer it but drive decent when taking it easy. I want it to idle, not have to two foot it at red lights. Give me some suggestions guys.

 

I would think you could pick up a 6.2L/6L80 combo for that budget, just saying...

 

Posi trac
4L80E
Turbo

go 14s, 13s, 12s, 11s.. you decide... haha

baby torque cam, and go. idles like stock, drives like stock and dont even have to put gears in it..




Well you asked....

 

If you want to spend 4-5k, what is the problem dropping 1k on a 6.0? I just don't see the point of camming a 4.8 unless its in a Miata.

 

If you have 4000 why are you afraid of the 6.0? You should easily be able to find one under $1000. Then tune it and you will be at the same price as the 5.3 with a cam and tune or less. Makeing the same power probably and should be a bit more torque.

If it were me I would build a turbo for the 4.8, should be able to build a custom set up for $3000 or so if you can do most of the work. If she blows then you have 1000+ to find another engine.

 

There is no replacement for displacement. Turbo or not.

 

Every 6.0L I have found has been close to $2000 or had a ton of miles on it. The 5.3s are plentiful. I am going to keep looking for the next month, maybe I will run across a 6.0 for a decent price. Remember this budget is for everything, including a trans and tq convertor.

 

I strongly disagree with this. The replacement is boost! Will you most often if not always make more power with more displacement, YES. But a boosted 4.8 will make a lot more power then many 408 n/a set ups.

 

Thats fine, I am a lil biased of my own opinion.

Have you boosted an engine yet? Maybe I missed the thread.

 

I haven't but there is plenty of proof! I will be boosting an engine next summer so I have done tons of reading and learning.

I don't see this as a matter of opinion but if you do then you are entitled to that.
