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 ..
It might be Tuesday before I can look at a couple vans, 2000 and 2001 to see if it has the mounting holes... Tomorow if I go by the shop on my day off...

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..

i dont want to modify anything else ..just for motor mounts ...i already am using the front style speedway kit with the front motor mount plate from speedway everything fits and works .
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:

so i can use this motor ....and yes it will bolt in the front? also the manifold looks to be a bit narrower than the older 80's small block ....if you have links for parts please post for me ..thanks oh and what kinda power does this motor make out of the box
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:

ok so the distributor i have with the bronze gear .cam and intake i will have to get .also the timeing cover ,,motor has less than 20000 miles on it..i just hope that it will infact bolt up to the front motor mount....
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.
I have a '99 Tahoe- vortec 5.7 . I'll look at it for you and let you know what I find.
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...
no problem fellas really appreciate all the help the motor is already pulled i just gotta pick it up than clean it up ...replace all the melted stuff thats on it..but for free i cant complain...
