LT1 vs. Vortec vs. LSx - The 1947 - Present Chevrolet & GMC Truck Message Board Network

You can usually get a 4.8/5.3 with everything ( harness,PCM and accessories) for under $1K here, with a trans ( 4l60e) for around $1500.00. That would be under 100K miles. Now I think you can do the swap for probably under $3K pretty easily ( 1500 motor\trans, 500 Fuel pump/pre-filter and misc, 500 harness rework and PCM flash, more misc $500.)

You will get better fuel mileage, depending on your foot, tune and cam you put on it, you will also get better starting and reliability. the LS motors will easily run 300K miles if you take care of them, my BIL had a 5.3 with 400K on it when he traded it.

Good luck with whatever option you decide is best for you!

I am going to put my foot into it no matter what, so I should still get better mileage, right...

4.8/5.3 is fine for a half ton gonna make tons more power than even a healty sbc would

I would stay away from the later model motors which i think is o6 or 07 just because I'm not interested in dealing with vvt/afm which can be a hassle but also can be removed as for the price of 1800$ for a long block you can buy a full 6.0 wired, accessories all for that with good miles

As for head flow I'm pretty sure stock tbi heads don't flow very well especially compared to 6.0 heads

it might be better to buy a wrecked car/truck for cheap money (if you can) that way you can take all the parts you need to do the swap then scrap or part out the rest, cousin of mine just bought totaled 03 truck for $1200 with a good engine and trans with only 65k
