a friend of mine has a im thinking 2000 or 2002 5.7 lt 350 motor he said i could have it for nothing it was in his van that got crashed and went on fire now i went to the house to see it the motor looks to be good but all the upper aluminum intake parts are a little burnt no biggie ..i know if i was to take it i would make it carburated anyway so a new manifold would be needed my question is ...will it bolt up to the front motor mount plate i already have..i couldnt see if there was any holes in front of the motor next to the balancer can anyone tell me if it would work thanks..

Is the engine a traditional 350 or is it an LSx type engine?

I think the traditional Vortec 350s ended in 1999 in pickups but may have been made for vans for a year or two after.

If it was the traditional engine, Vortec version, you could readily mount it in a 55-57 and convert it to a carb using an Edelbrock or other manifold. You will need an electric fuel pump and some other details.

2000 or 2002, I doubt it being a LT engine...
Most likely a 5.7 Vortec L31... Used through 1999 in trucks and 2003 in vans...

Sorry, I don't know if it has the 4 mounting holes...

yes you may be correct it was in a van ...center bolt valve covers instead of outter bolt valve covers..van was in a fire but motor looks to be good i was just wondering if i coulda mounted it like the older style 80's and down small blocks with the front motor plate ..i mean its free but i dont want to have to re make mounts just for the motor if thats the case ill spend some money and buy a 350 that will mount with the front 4 holes ..

Depending on the miles, and condition you might just have a good engine. You can get simple side motor mounts from any of the Trifive vendors and it will go right in..

Yes it will work it has a plastic timing cover that is probably damaged from the fire and a steel one won't fit either due to the different pattern however the covers are cheap on ebayand can be reused despite what the gm manual says. the cover also has a hole in it for a crank sensor but gm offers one without the hole. also these motors are factory roller cams so you can get a ramjet 350 cam and have a lopey idle too . good luck:happy0030:

from the factory in stock form they make about 260 if you put a cam and a good intake like an rpm air gap it will make 350 hp really easy . it is a vortec motor and thusly you will need a vortec type intake manifold for it. your standard sbc manifold won't work . also you need to use a bronze or melonized distributor gear due to the roller cam. this is the same long block used in the ramjet 350 and 330hp crate motors just with a milder cam. good luck. :happy0030:

jlow, although they only used the front mounts until 1957, they continued to put the 'bosses' on the blocks for years after. They just needed to be drilled and tapped. I think in the later years, they were drilled and tapped, but they used them for accessory mounting, like power steering pumps and such. I have an 89 block in the garage, which was the 'post 86 vortec' type, I'll look at it when the sun comes up and let you know if it has the holes there.

The block that I have from an 89 Suburban is drilled and tapped in the front, as I said, for accessories. I'm not sure if they're in the exact same location, but they look to be.

All bolt holes in the front of the block are the same on all small block chevys. it will bolt in right where your other engine is :happy0030:

The stock bolt-on front brackets won't clear the big 8" balancer that that engine will have.

I believe it will fit with a little clearance grinding on the bracket or just get a 7" balancer...
If you change the balancer you might have to re-mark the timing mark on it to the right location, some are different...

Looked at a 2001 Vortec 350 and yes the holes are there, also checked a 95 LT1 and it has them too... Just be sure and check for threads in the holes after you pull the engine, I do recall that they are not always threaded...
