what do you drive?

Like I said all I know is that it is supposedly a 350 Big Block. Both my dad and grandpa didn't believe the person we got it from and we didn't think anything about it. Then the guy we bought it off of said the same thing again so we checked it out.  "By the way, The person we got it from was a friend of ours and his dad is also a mechanic." "Damn Coldblooded we have way to many mechanic's here in Dublin lol" but anyways. Then my Ex-Girlfriends dad wanted to check it out also and he said it is just a factory 350 Big Block engine. He said they didn't really produce many of the 350 Big Block it was more for experimenting and testing. It doesn't lose much more gas milage and it has just about the same Horsepower but has a little more Torque. That's why our friend put the big rear end and transmission under it. Here are some photos tho. Like I said you can't tell the different by looking at photos. You just got to believe me. We didn't think it was ether until we actually looked at it.

Here are the photo's of my 1991 engine.

I know exactly what you mean, term.  I want one like this some day:

If that is what you think my International Harvester looks like then your wrong way wrong. Here are some pics of it. I might make a video of it in action one of these days.

So the truck supposedly came with this engine from the factory?  If so, can you post the truck's VIN number up here?  This is fascinating to me...

Heres a complete list of every GM 'big block' motor ever used.   The 348 is technically a big-block, but it was basically replaced with a 409 and taken out of assembly..

actually, if you remember, I also asked if it was one of these:

Wikipedia could be wrong, though.  Whoever wrote the article might not have known about an experimental engine.  Even so, I can't find ANY credible reference of a BB350.  Thats why this is so intriguing to me.

Term, here's a good link to see the physical size differences of the Chevy engines: http://www.enginefactory.com/chevdimensions.htm

Well like I said it was an experiment and I guess they didn't like the results so they didn't even both with putting it on the lists. All that I know is that it's a good reliable engine and the engines average temperature is a little higher than most. It is like at 220. Which is over boiling point. The average is around 180-200. Boiling being at 212. I changed the Thermostat thinking it had a leak or something but it didn't change the temp. There are more 350 Big Blocks out there then you think they are just built for drag racing witch are custom or specially made but entirely different setup then my engine. I wanted to get like a 69 Chevy Silverado with a 396 those are some badass engines. In my opinion the best engine GM ever came out with.

If this is the case, and its that rare of an engine, how did your friends and family KNOW right off the bat what it was?

Term, seriously dude.  I couldn't find word one about a 350 Big Block.  Get a tape measure out and measure your engine.  Compare your measurements to the chart.  If they're close to the small block measurements, YOU HAVE A SMALL BLOCK, and you were misinformed by the people you know.  If they're close to the big block measurements, you are correct about your engine, and you have something really cool.  Now, if it IS a big block, I'm curious how you know that its a 350 and not a 366 or a 454, but thats another discussion entirely. 

Seriously, take the measurements.  There's no shame in being wrong, but if you can prove that you're right, then you have an even better conversation piece because you can show people its true.

Also, despite what you might think, that engine wont last long at those coolant temperatures.  Try running the engine without a thermostat to see if the temperature goes down.  If it doesn't, either your radiator is clogged, your water jackets are full of crap, or your water pump is on its way out.  My guess is that its the radiator, but like I said, check your thermostat first.  I know you said you changed your thermostat, but I've had brand new ones be bad before, so its worth double-checking.

here it is

Nice!  Those are good, solid trucks.  Ford rules!

Love the SHO in the background too!  Ditch that stupid Chevy Cavalier though.  Those things are junk. 

Is that your shop?  I would kill to have a big barn like that.  Very nice!

the sho is my aunt's i love that car  twin TB  all wheel drive and 300+hp  the shop is full of everything but cars lol
but yea i love my truck

[Gemma]

At 220, I wouldn't even drive it till you get it figured out.  When my water pump in a 454 went out, it didn't show any signs of struggle, just suddenly over-heated and I pulled it over, luckily without any damage.  I'd be looking at your radiator.  Maybe it is some weird-ass motor some tweaker put in there, and its just not cooling right with the initial radiator. .   I dunno.  Your truck is a mystery shrouded in an enigma. 

[SnKMaddog]

Term, please man.  This is nagging me, and will continue to do so until I know what the deal is.  I would love to have the VIN number of your truck so I can decode it.  I would also love to know all the measurements of the engine.  If there are any emissions stickers under the hood or visible casting numbers on the block, that would help too.  Lets figure this out for sure.  Take measurements of the five different points listed in the link I posted earlier.  Or at least measure from valve cover to valve cover and from back of intake to front of water pump.  I'm really curious what the measurements are.

[SnKQuaKe]

If I were asked to go measure my engine to satisfy someone's curiosity id say no. lol

Maybe when it warms up some or this weekend when I add some oil and some ... damn I forgot what it is called. The thing for the steering. Power steering fluid. I couldn't think of what it was called. lol Ya I could use another radiator mine is kinda bent up a little. I was going to use that little brush that straightens it but couldn't find ours when I had the grille off for some headlight wiring.

[Gemma]

Your radiator is the only way your motor has of getting heat AWAY from itself.  Don't mess around trying to straiten the tines man, just get a new radiator.  They're super easy, especially if you've got some help from your dad or grandpa.   In the mean-time, if you're going to run it that way, you might wanna get some thicker oil.  I'd go 10/40, or even strait 50.
