I do not think the point of this thread was to start a war about why not to mod the 4.8. He was simply saying what he had for a set up. Quite frankly you set your self on fire by posting that asinine comment, esp for some of the half baked ideas you come off with.

But to me it makes no sense to spend $1000-$1500 and have virtually no where to go N/A. When you can spend $1000 or less and be making the similar power with massive potential for up grades.

If I had a 4.8 it would be swapped instantly or FI. I can understand being proud of your work but for me money needs to be spent to get the absolute best bang. There is very little value doing bolt ons and cam to a 4.8 therefore it is useless to me.
Just have to keep pushing the envelope, don't you... You have to consider that he is likely on a budget like everyone else on this site, and may not be able to afford a 6.0 swap. You should be the one to talk about working on a budget, considering your throttle body project... Either you made that thing because you had no money to buy a TB, or you are completely ******* crazy...either way, you have no argument.

I am sure it wasn't the OPs intentions.

This thread is a great solidification of the argument. If you aren't going FI then the first $1000 you spend is generaly best spent on a swap. Most everyone in this thread has at least $1000 invested so the budget argument is irrelevant. I have seen some true max effort 4.8s running mid 12s I beleive but I would guess the large cam and 4000+ stall wouldn't make for a very good daily driver.

I certainly know about being on a budget. Why do you think my truck sat for a year before being able to afford the top end. The best budget build is a 6.0 swap. Anyone who can put a cam in there truck or swap a set of headers should be able to unplug some wires undo motor mounts and separate the engine from the trans.

Again, this thread was not started for any solidification of what to do, simply to share what he had.

Well using your logic it is a waste to even mod a truck when the same motor in a car would be faster... Everbody has different goals , budget, etc etc and if somebody asks for advice or knowledge about a certain combo, then you should give advice or knowledge on THAT combo. If you have nothing positive to say as far as technical advice on that combo then you should stay out of conversation. Another thing is looking at your timeslips you only picked up 5 mph on the bottle so what are you running ? Like a 50 shot . If so that is a complete waste to even install nitrous and only run a 50 shot when we all know the LS motors will take much much more and hold up fine.

I feel that the information given in this thread is a solid reason to give info on THAT(4.8) combo. It showes that there are better ways to spend your money in my opinon.

I was running 100 shot on a 240,000+ engine. I planned to up the juice but started my 408 instead. I know how much these LS engines can take.

Hey guys new on here I got a question. I got a 2000 4.8 Silverado that I've had for a few months and I was thinking bout showing it some much needed love by putting boltons and 212/218 low lift cam, long tubes and exhaust, cai, pcm tune any ways long story short if I do all these mods to the 4.8 and then decide on swapping a 5.3 can I put everything from 4.8 to it oh yeah n if the 5.3 would run the same or better with the tuned 4.8 pcm also it is a daily driver.

Yes you can swap everything from the 4.8 to the 5.3. The cam is going to be iffy because a cam for the 4.8 will be a touch small for the 5.3, but, you shouldn't leave too much on the table.

If you notice my opinion and that of many others is to swap the larger motor before modding the 4.8. A 5.3 or 6.0 is a direct bolt in place of the 4.8 and only thing you need to run is either a stock 6.0 computer or ideally a custom tuned($250) on your current computer. It is around $1000 for a 6.0 or 5.3 and if you get lucky you can pick one up for $600-$800 easy. It will not take you long to blow threw $1000 modding the 4.8. A decent cam swap is $800 plus alone.

The funny thing is is that fooses motor is not built near like your glorified 408 is going to be and even with you on a 150 cubic inch bigger motor he will still pull the **** out of your piece of junk. And did you really have a 6.0, tune and converter and only run a 14.2? If thats the case than you must really suck at this whole modding thing. I really think you should just find a different hobby, birdwatching or basket weaving maybe?
