4.8L in our trucks? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Pl4yboy · 12-29-2007, 09:53 PM

Has anyone seen one of the new 4.8s transplanted into our trucks? I was driving my sisters 07 1500 today and realized that those little things have some serious GET UP. I was driving tonight and broke them loose going 35. Has anyone seen the numbers these little motors are making?

The 4.8 is nothing to scoff at. But if you are going through the trouble of putting the LSX style engine in and the wiring then you might as well go with the 5.3 or 6.0. They make more HP and TQ and get about the same mileage.

I have a 4.8 in my 67 but it is bored to a 5.7

I got a 5.3 in mine (51) in stock (mechanical) form, they will suprise the heck out of ya.

If you have one, 4.8 or 5.3 and all the trimmins, they make a very nice addition/power plant for our trucks. A few tweaks required, but the 4.8 should be a great motor for your truck if you already have it, go for it.

5.7 in mine out of a 2001 Firebird WS6.

There are several threads here (and poject threads) covering what is required, where to hunt the info, etc. Search the forum for: GenIII

Lots of reading to do this swap. It's not too hard though. Worst part is a) trying to get the engine bolted, b) find headers that will work and c) getting the wiring hacked and computer reprogrammed.

I've got a 6.0 and then some, seems to have plenty of power, lol

Pl4yboy · 12-30-2007, 04:52 PM

I wasn't planning on transplanting myself. I have a nice 350 in mine. I was just wondering how the 4.8s power such big vehicles so easily with such small displacement.

i was just thinking ab. the new setups i just found a 5.3 w/the aluminum heads correct me if im wrong but its suppose to push 340 hp stock.. looked one up at a salvage yard couple days ago, its suppose to be out of an 07 tahoe 2k w/tranny wiring and ecu.. worth it? 2k miles also

Sounds like a good deal if thats the real deal. I'm too drunk to look it up at the moment. Will look tomoorrow. <3

smoky02 · 12-31-2007, 01:39 AM

Hell yeah that's worth 2k...or at least it is to me...LOL...but you could find one cheaper...just have to be patient and look for it.

shifty · 12-31-2007, 05:54 PM

2k is worth it, I would buy. Drop another $2k on peripherals it and you've basically got a bolt-in affair on your hands. Go from 8-12mpg to 22-28mpg in less than a week if you work diligently.
