350 block w/vortec heads
 

I have a 1998 350 2 bolt main with VORTEC heads I really need to get out of my way. I'll take $300 and that will get you the block, heads, valve covers, oil pan, push rods, roller lifters, rocker arms. Does not have a crank or cam. Was going to build 383 but changed my mind.

350 block/Vortech heads
 

Sent you a PM

do you still have this for sale?

yes

:whine: Why I gotta be on an island?!?!? Thats a deal I would grab in a heartbeat here!!:whine:

A little curious here. All 98 350's were vortec 350 motors. ALL vortec motors are 4bolt blocks. :confused: :confused:

1998 Vortec engine
 

Well buddy you're wrong on this one. This motor came out of a 1998 Chevrolet truck. I thought for sure it would be a 4 bolt, but when I pulled off the oil pan there were only 2 bolts on each main cap.

gldevall, i used to work for a GM dealer, and with all of the L31 blocks i have seen, all were 4 bolts. the service replacement for the block is PN: 10105123

this is also the same part number as the factory replacement block that you will buy from a GM dealer.

I'll get the number off of the block and post it. I'll also take a picture of it showing that is only a 2 bolt main.

this is really interesting :)
kinda like those super rare 4bolt 305's

Well, it may be a 305. But I was told it was a 350. Now you guys have me wondering what the hell kind of motor I have.

hmmm, never thought about that. It might be a 305. Just take a head off and check the bore size. If its under 4", its not a 350 ;)

Block Clarafication
 

OK guys, I finally found out what I have. I found a casting # on the top of the block near the rear and it is 10243880. It has a 4" bore and I looked up the casting # and found the following.

MorTec.com

"10243880...350...95-00...2 or 4...Vortec truck, Gen.I crate motors and "ZZ4", roller cam, one piece rear seal"


I also took some pics of the block and the heads that I will post tomorrow. Any more questions? Just ask.

Thanks to everyone,

Gary

How far are you from Beaumont?
Do you still have the engine?

Yes, I still have it and I'm about 3 hours from Beaumont down I-10.

TTT
All still available. Any takers?? Will sell separate.

how much you want for the heads?

what kind of shape is it in? i would love to take it off your hands but i'm eight hours away.

I think the 1st $275 will get the heads.
