So I was telling a friend today that I am looking at Tundra's and that I would never own another Chevy. He told me that he heard that the Tundra has a Chevy engine? He said it is a Chevy 350. Is there any truth to that? Just asking for my info, I don't want to start a war.

Interesting? I don’t know, but in today’s world that would not surprise me. Isnt the 6 lug patterns from the first gen and Chevys match?

I know my 4.7L can crack the shit out of the Chevy 5.3L

 

[Gutz]

I don't think that's true.......????????

our tundra engine with a 94mm bore (all V-8's) is no 350
the 350 has a 3.875" bore where ours is 3.7"
have your friend explain that.

the 350 has a 3.875" bore where ours is approx 3.3"
have your friend explain that.
does toyota add material to the block?

toyota has no reason to steal old technology from gm

I don't believe the Tundra has any components from GM in it; however, it wouldn't be the strangest thing in the world if GM and Toyota shared technology or parts considering their past business relationships.

Also, no one suggested that Toyota stole technology from GM.

I didn't say "Steal" and I don't want to start a thread going that direction. I was just trying to see if anyone had also heard of this and if it is or isn't true.

No, the Toyota 5.7L (5663 cc) is not a Chevy 350. Chevy small blocks aren't offered in a 3.7 in. bore or a 346 ci. displacement. The engine is a Toyota original engine (aluminum block) and is only offered in the Tundra, Sequoia, Land Cruiser 200 series, and the Lexus LX 570.

 

[Toxarch]

The engine block is cast by Bodine Aluminum which has been owned by Toyota for 19 years.

The engine is assembled at Toyota Motor Manufacturing Alabama.

gah... just found where i got that info and indeed all tundra engines from the v-6 all the way to the 5.7 have a 94mm bore...
you are correct and I am edited

HECK NO!!:bs:

 

[xjblx]

Probably the only thing the Toyota 5.7 and the Chevy 350 have in common is that they're both V-8's.

 

[FJtoTundra]

I had heard rumors a long time ago, when the T100 came out, that GM would supply a small block V8, but it never happened. I did find an article on that.

As far as the Tundra's, never heard of that either.

which engine has a 3.7 bore?
one thing that stood out to me as being cool was that all 3 v-8 iforce toyota blocks used in tundra, the 4.7, 5.7 and now 4.6 share an 84mm Bore
the stroke and differences in head volume is what accounts for the displacment (or so I read in a tech article somewhere between here and there)

not trying to be a dick, i just live and breathe useless info and im bored so figured id ask

The 3UR-FE 5.7L engine has a 3.70" bore (94mm) and the stroke is 4.02" (102.0mm).

See the attached file. It's actually a Land Cruiser file but it's the same engine as in the Tundra.

Besides, I don't believe that Chevy trucks have a DOHC with with 32 valves....?? If they built a motor like this wouldn't they put it in their own truck?

heh, I edited a bit back, I found where I got that info from, I was off by 10mm

they do all still have the same bore though from the v-6 all the way up!
thats kinda cool.

I’m curious Tox, what do you do for a living?

Edit: Since we know that they don't share components, my Honda Passport did have a ton of AC Delco parts in it.

There's only one of me.

Yes, shrubberies are my trade. I am a shrubber. My name is Roger the Shrubber. I arrange, design, and sell shrubberies.

That makes sense because the Honda Passport was actually an Isuzu Rodeo AND Isuzu and GM were buds back in the day (the S10 pickup was OEM'd by Isuzu as the PUP in the late 90s / early 00s).

The auto industry is very incestuous, which helps drive costs down while providing variety.
