I am going to get another Vortec block, free exchange from the same seller, will see how that goes. I am sure that they are of better design than the old style. My machinist was just telling me what he had seen of them. Another thing is that they are ballanced differently and he said I need a vortec specific flywheel? He is a racer, builder and has been around for a long time. Anyway, this guy is GOOD. Alot of guys use him and as I have said before, he doesn't jack you around. He said you could go .010 over on the cam bearings but that .010 wouldn't have cleaned up that particular bearing journal, the bearing spun and freely slid in and out of the journal. Was pretty nasty. Thanks dmyntti for your input, it does make me feel better about using the Vortec.

Just got back from ALMOST dropping off the motor. My machinist did NOT want anything to do with the spun cam bearing. He said it would never be right, also voted against using the vortec blocks and rods. Apparently they are not forged, they are powdered metal, and break easily. SO I am in search of another block. Hopefully I can get my $$ back AGAIN for this piece of cast bulljive. Man, this is really disheartening. Luckily they guy was selling the block and heads seperatly so I will hopefully be keeping the heads and get my $$ back for the short block. I am going to seriouly look into buying one of those ballanced short blocks from someone like summit or whomever, maybe even a 383 or something. Any suggestions? I am still trying to keep this cheapISH If anyone has a deal or input or ENCOURAGMENT, please subit it HERE!!! I am so bummed right now... This SUX!!!!!! UPDATE Just got off the phone with the guy and he is going to get me another block, will see how that goes...

THis is why i don't have cable, or dish. 60/ month to watch a handfull of chanells is just nuts to me. Plus I am finding that the less I watch tv, the more I work on the z, or doing other stuff that counts Untill you can pay per channell here, I am not paying for anything. My rabbit ears work fine

Thanks, I will get it to the machine shop on Friday. I will tell him what I am wanting and get his quote. I got the ballancer pulled last night, so I could get the crank and cam out. Crank is out, the cam however, spun a bearing. THe bearing came out of its housing towards the BACK of the enging adn got crushed a bit. The cam will spin but won't come out. Will take it to the machinist like this, hopefully he will have some ideas. The front crank journal is horendous! This engine lost pressure, and although it didn't run long after it lost pressure, it was enough to badly score the front main, the rest are decent. I hope we don't find cracks under all that caked oil goup. If so, I am going to start getting tired of Engine searching!!! Will see...

I will venture to say something similar happend there then, because it was NOT in the pan. Thanks dmyntti! So, I am looking to replace the stock roller cam with another? I CAN reuse these lifters right? Since they are roller? How much is a roller cam and spring set?

Looks like 300Ft/Lbs from 1500 to 4500. This will be mostly a daily driver with a T-5. Do you know if this is a roller?

Apparently this is the stock cam specs for the L31 5.7 V8... HR 202/207 .410/.424 115 L31 Vortec Any comments??? 225 HP and 330 Ft lbs. I think for the sake of time and money, i will try to reuse the stock cam unless someone can convince me that a different cam and the expence of modding the heads is worth it. I am open to suggestions but 330 ft lbs is looking good! Plus i don't have to break down the heads. I won an Edelbrock Performer intake on ebay and looking at a used Edelbrock 750 for now. Just FYI.

Jeff, the guy here at work that knows at least one guy for any task at hand dealing with cars has no one. He said that radiator shops used to but don't want to deal with them anymore. Looks like you might be on your own. Let me know if I can help out in any way, would be interested in learning

I started tearing down the Vortec I got last week. The lower end HAS been rebuild but VERY VERY recently. I have a couple of questions about this new style bock. Are these roller motors? I guess I will find this out this evening if i can get to it, the lifters have flat spots and a keepr that keeps them from rotating, so I am thinking roller lifters right? But no roller rockers There is a crank trigger on the front just behind the Ballancer, any thoughts on what I could use this for? I am going carb for now and wondered what I might utilize this sensor for untill I can afford injection. The ballancer is 7-3/4", it needed to be 7-1/4 right? How much clearance is there? If I bump the mounts back in the "slotted" poition can I clear? The main caps are "only" two bolt but the bolts are bigger than the old style, 5/8 heads instead of 9/16, the spacing looks to be a bit wider and over all more BEEFY The rods are also wider, again BEEFY. I am happy with the overall condidion, the bottom end (as i said before) has been gone through, every thing is number stamped and the xhatch at the bottom of the cyl's is still there and sparkly, could not have hardly any miles. The ONLY concern of mine is what I found in the lifter galley under in intake. The oil was glossy and caked on the walls of the galley and there were several chunks! of this porus oily coal type crap. Big chunks and I am sure there were a lot of little chuncks lost in there too. WHat is this stuff? Never seen it before. Thanks for your thoughts, I am hoping to stay mostly stock in as is condition, of course I will take the entire assy to my machinist to have cleaned and I will put new springs in the Vortec heads. If this is a roller, will have to think about putting a differnt cam in, thoughts? Should I match the roller cam with rockers while I am at it? Just can't seem to stop typing. Adress what you want, I am all ears!

Sorry to see that time, I can't say I feel your pain but I scratched the top of my Z this eve pulling out the weed wacker. No poo, Sucks.

Glad your ok, stick you 4 wheeled toys, much better off.

I like purple I am still interested in using these but don't want to end up with the extra set of headers. Some are going for 160! Anyone got a second SBC project that would buy them from me if they don't work on the Z?

Finally got that little bastard!

Well I bought the motor, it was hanging from a tree! WEIRD. So anyway the guy is going to deliver it today, he hadn't taken off the accessories or the intake yet. He turned it over with the flywheel and it had good compression and everything looked good. The rods are really FAT, and it is only a two bolt, are all newer blocks this way? PYRO, I am going to go mostly stock, will do the cam change now since I am going to go thru the motor anyway. It lost oil pressure and I don't want to risk spinning a bearing after I take it around the block once Getting excited, this think will hopefully be running by Septemer which is the Texas/Oklahoma track day at hallet race track here in OK. Hopefully there will be LOTS of HYBRIDers at this event as I would love to meet some new Z freaks. Most of the guys here are into Stock, which is fine but they show no love for the V8. Anyway, will keep you all posted on this small block build. Grumpy any cam suggestions for this 350 Vortec? Will be using a performer intake, 750 edlebroc carb, T5 all in a 260 z with subframe connectors. I will match the springs to the cam but other than that it will be stock. Oh yeah, it did come with the stock exhaust manifolds from the 98 chevy truck, will those work by anychance??? Thanks!

It is a 5.7 L. Is there any worries with the crank or rods with this 98 block? A guy told me they were weak, dunno if he knows what he is talking about, I thought I would run it by yall. Going to pick up the motor tonight, guy went clubbin last night and wasn't home, LOL.

Safety First LOL

Does anyone have the newer one or both, is it worth the price to get the new design?

For $650, complete long block, came out of a 98 chevy truck. Said it was 315 hp stock. No intake or dist. His Story... Guy's son was driving along and the motor lost pressure, pulled over asap, took it to chevy, they replaced the long block. Guy sold it to his dad and he pulls the pan, the sump had came apart from the oil pump. I can re-ring/bearing/gasket this dude for cheap! Buy an intake and maybe the cam. What do you guy's think, will the stock cam be too torquy for the Z? The heads are stock so they don't have the higher rate springs. Should I leave well enough alone and put this back together stock or what? Suggestions again. Machine shop said he won't charge me for any part inspection, this guy rocks, just for work completed. I will look at the motor tonight or tomorrow, get it and go from there. Will be only 450 more than I paid for the crap long block I am getting my money back for, I am happy again.

THanks for the input fella's, I am open to suggestions. The crate's seem to be a bit too pricy for me. I don't want to spend 1400 on a long block that is bone stock. I am going to see about this $200 shortblock that needs assembly this eve. Seems like a good deal. I want to run the Vortecs, the HE cam PYRO mentioned, a RPM or Performer intake (Any input on the actuall differences between these?) and a 600-750 carb, I think I am getting a deal on a 750 from a member on here, so most likely will be that.

Cell is mounted and in place, looks good. I still have to get my fuel filter and lines aranged. I got my JTR kit and when I get this cracked block back I am going to bolt it up the tranny and dry fit it in the car, drill my holes and any other fab stuff that will need to be done. There is another block in Manford with new pistons and the machine work done, just needs to be put together, for the same price 200. Will see how that goes. Oh and I have been working on the Free pooltable, that is going fairly smooth

Come on over to OK! Couple of years ago we got rid of all state inspections. Sure, there are alot of cars that drive around stinking up the roads, but you could be one of them! YEHAW

15 times in each hole with the tap, sounds like you could have over sized the thread ID, are you sure that the 4 or so that bottom out do not wiggle at all?

Machinist found a hairline crack in the lifter gally called the guy that sold it to me and he is giving me my money back. anyone need a crank and a set of rods ? He didn't want any of it back. Back to the dwg board. This sux. Side note, I went 4 wheeling on my wife's uncles land this weekend (first time). What a blast, going to be looking to buy one soon, need you guys to tell me to finish the car first Anyone here have a Yamaha Wolverine? Likes dislikes? Will start another thread when i find alother pwr plant.
