4.7 vs 5.7

[Dook13]

Hey guys I'm new to tundra talk and I need some help! I am buying my first tundra and I'm stuck between a lower mileage 2008 4.7 trd with 36000mi and a 2007 sr5 5.7 71,000 mi. I understand that the 5.7 is the best option for towing but is it worth going with a higher mileage truck fOr the occasional tow? Any help would be great thanks! Also at 71,000 is the 5.7 going to be dependable over 5 years? The price difference between the two is minimal

5.7
I bought a 4.7 and within 1 year traded it in for my 5.7.

5.7. You get a better tranny, stronger rear diff, better gas mileage. You didn't mention price or option differences, I'd pay more for a 5.7, better resale too.

The 4.7 is much too small for a vehicle of this size and will not produce sufficient acceleration for drag racing.

4.7 is a powerful engine. 5.7 is a monster. You can't lose either way. Ask yourself if you are likely to regret not getting the monster engine later on. If you are, get the monster. Hey, I haven't towed anything yet and I don't feel guilty. And when I step on the beast, the feeling is awesome.

111k on my 5.7....nothing but maintenance but I don't tow much either

4.7 requires timing belt changes too...

5.7L no questions asked. Dealers in my area cannot even sell the one 4.6L engine they have rest are all 5.7L engines. However, if you are getting a 2wd ONLY, then 4.6 or 4.7L is perfectly fine in my opinion. If 4wd even if not going to use it much, get the 5.7L no doubt about it.

Dealers do not even want a 4.6 or 4.7L as a trade in and low ball you more than you would expect come trade in time, at least in my area anyways. Gas mileage difference will be minimal 1-2 mpg at most and if tow anything, the 5.7L will get even better mpg not working the engine nearly as hard.

I was going to get the 4.6L over the 5.7L, but 2 dealers convinced me otherwise on this. Bigger is almost always better.

I bought a 4.7 used and i regret it. I don't need the 5.7, but want it. Also, if you don't regularly haul things in the bed of your truck get the crew max. I love my Tundra but i wish it were a 5.7 CM.

Get the 5.7, try to talk em down as low as u can. But here is some reassurance for u, I have 185k on my 07 5.7 general maintenance, alternator & starter.

I have the 4.7 and it is fine. I also have the grade. Would I have like a 5.7 limited, well yeah at the same price and quality.
I've hauled 5 tons with my 4.7 without problems.
Concentrate more on the two trucks and compare options and wear.
You will be able to deal more on the 4.7 because there are people who hate the engine. Funny thing ,it was the engine to have in the first gen. and they were not that much lighter.

I've seen this come up a few times and there is a constant theme.

No 4.7 owner is going to complain about their engine, it's a solid performer. What you hear them say is the 4.7 is fine or it's good for what I need.

Most 5.7 owners talk about turning off their nannies, having fun, it's more engine than I really need.

You will not hear, gosh I have too much power or wow I'm bored.

Something to think about, if you are going to lift and put bigger tires on, or you are going add a camper shell, the 5.7 will only help.
