If that is supposed to be a link it isn't. Even with out seeing a link, I can tell you your transmission will hold up just fine assuming it is in good running order.

Re: lg4 to orange block 350 with 325hp

How does a company sell a NEW 325HP 350 for $1,500?

If it's an ebay motor, run the other way. I looked at a third gen with a "400 horse ebay motor". He had the reciepts totaling 2 grand, it was clearly the same motor. It was also nowhere near 400 horses when I laid into it.

This one maybe ?

"This Engine has The First Generation Swirl Vortec Heads "; just to confuse a unknowing buyer into thinking they have real Vortec heads ; not earlier swirl ports

Always worries me when a seller takes 4 pages and lotta colors to describe how good his engines are
The only time they mention a brand name of a product used it is a a lower end one ( Speed Pro ) so what part of China do the rest come from

Re: lg4 to orange block 350 with 325hp

It worries me when the list of parts is vague. It worries me even more when their is no mention of any of the parts that actually determine it's power output.
It's probably possible to squeeze 325 horses out of a high compression small cam Vortec motor but I'd be skeptical.

Even if they did get 325hp I'm sure it was on an engine dyno, using dyno headers, turning no accessories, etc.

Re: lg4 to orange block 350 with 325hp

We have all seen this game played a million times and there are a nearly endless number of either frustrated, disappointed engine swappers or blissfully ignorant ones who are confused about why 90s minivans can outrun them.

Do yourself a big favor and read through this thread:

http://www.thirdgen.org/techboard/tr...tion-side.html

There are many like it, but this is just the most recent example.

If you want to believe some ebay dude's marketting hype and vagueries and think you're actually getting a 325 hp 350 for $1500, then by all means go ahead and spend all your money and work on it.

To get 300hp out of a 350 requires a lot of attention to detail, and good, well-matched parts. It's not hard, but you have to know what you're doing.

Re: lg4 to orange block 350 with 325hp

325 HP with swirl-ports takes an awfully huge cam. In this scenario, the cam starts working just when the heads are all done. Worst compromise possible. No low-end TQ, no top-end HP, and no driveability. THE ONLY all-new 350 for $1500 is GM's own Goodwrench, and it's nowhere near 325 HP. Sometimes you see claims around 250 HP, and that's possible if you don't figure the p/s pump, a/c compressor, et cetera. But if you want an all-new 350 with a warranty, it ain't a bad way to go. Be aware it isn't really 8.5:1. It's actually 8.0:1 w/ GM steel-shims, or 7.8:1 with GM 0.028" composites. Comp's PureEnergy makes for a perfect upgrade cam for it. Then you can hope for around 265-275 HP with headers and a decent intake. If you want 325 driveable HP, it's going to cost more. If you want a warranty, it'll cost a lot more.

Re: lg4 to orange block 350 with 325hp

Oh maybe they are on eBay I just googled 350 engine and it gave me a list of sites.
It wasn't eBay or Craigslist but the link (Vetteoz) posted does sound just like it!! No pretty colors or 4 page write up , but yes ebays seems to be same parts.

Thanks guys

Re: lg4 to orange block 350 with 325hp

Obviously everybody else who responded is right but I am still trying to get past the gimmick Midnight Hot Sale Orange part or the description. I am definately not the most knowledgable but none of that means anything to me and doesn't even sound like a good gimmick catch phrase. I might let the Orange go though.

Re: lg4 to orange block 350 with 325hp

I can't clearly ID those heads as vortecs because the picture is too small, they are obviously center bolts. They claim they are Vortec heads but many people call the earlier TBI swirl port heads "Vortec" heads.
If it's a swirl port set of heads, no way in hell in any scenario they are making 325 hp.

I'm about done assembling a true 325 HP motor , reusing the rotating assembly (polished crank, new bearings, rings, etc) I'm in it for about $2,200. I had the long block (vortec heads) laying around. Only labor I paid for was $800 in machining on the heads, valve job, mag/polish crank, install new springs/retainers/locks/seals/guides. About 9.2:1 compression; took a 224/230 duration .502"/.510" cam to get there.

Re: lg4 to orange block 350 with 325hp

my goal is to just have something fun to drive around in, not looking to do 10s on the street! but would like to break 13s when i want to mash my foot to the floor. real 250-300hp from the rear wheels would be nice.

it is and will remain an everyday driver, emissions not a prob, but decent fuel mileage would be nice when driving like NANA.

i want go,mileage, and highway manners. dont want to cruise at 60 at 4000rpms

Re: lg4 to orange block 350 with 325hp

You have a ton of options for a 12-13 second car that can break its tires lose on demand... can it be done for less than $1,800? Maybe... but not reliably. I am telling you though, that motor you are looking at won't blow 13's even.

Your options are unlimited. If I was you I'd find a cheap high mileage Vortec 350 that's in descent shape. From my experience they are usually in awesome condition as long as they weren't starved of oil. I had one with 275,000 miles that still showed cylinder cross hatching, reusable lifters, crank measured perfect although I had it polished while it was out, new rings and all new bearings. My labor to have the block cleaned, inspected, crank magnafluxed/polished, new cam bearings and new freeze plugs was like $300. I had to purchase all the bearings (which shouldn't be more than $100).
For the heads you'd want to have them cleaned up, valve job and rebuilt with new springs/retainers/locks/seals/screw in studs. I spent about $350 on parts and the machine shop did everything from disassembly to reassembly for about $500. My factory pressed in studs were very secure and probably didn't need to be changed for what I was building. Could have saved $150 off the total price (parts and labor) if I didn't change them. So for around $850 you have an awesome set of heads. (You can also buy them from Scoggin Dickey for that price).

Total price is around $1,250 at that point. Factor in another $300 for the cam, $50-150 for rings, $50 for the oil pump, and about $200 in gaskets, push rods and water pump. You would be right around the 2 grand mark and still need rockers (vary depending on what studs you use $150-250), timing chain, vortec specific intake manifold and a carb. You'd be around the $2,600 mark not counting what you paid for the motor.

Easily can make a reliable 350+hp/400 ft lbs out of a daily driver Vortec 350 for about $3,000. Can get you into the 12's relatively easily if your car is set up right and would make a very fun street car with all that torque!

votech 350? does it matter year? i like the carb set up rather then fuel injection..
what would i need to put this in my car? my 700r4 was rebuilt about a month ago i have a transgo shift kit not installed but i herd its better then the b&m.
i can get a vortech from a wrecked camaro few streets over from me. for about $1000 it has 80k on it and runs great back of his car wrecked front end and motor untouched

There's no H in Vortec. It ONLY applies to 96-98 trucks. I think there were a few in 99 and 00 that might ahve still gotten those heads, but you're looking for an engine from a 96 to 98 truck that has 906 or 062 casting heads.

Do a stock rebuild, upgrade to LS2/LS3/LS6 style GMPP "yellow" beehive springs, Comp beehive retainers, run 1.5 rockers, and an LT4 hotcam and you'll be in the 330-360hp range for pretty reasonable money.


And to be completely clear, I think these ebay engines are probably reliable and well-built, but they're just not performance engines. Its not hard to build a reliable engine at the power levels these engines are probably at, and with that in mind they're really not that bad for the money, but that engine that vetteoz linked to, with its factory roller cam, is still going to be a better buy and a better deal. Just swapping in something like an LT4 hotcam (some minor tweaks needed to make sure that works out due to lift limitations of those heads) will make it a total beast as long as you can fuel and exhaust it adequately.

The other concern is that these factory rebuild type engines dont use ARP rod bolts. In and of itself it's not a huge deal, just a little high RPM insurance for down the road if you ever want to spin it to 6000+ RPMs.

I'd say that package would be good for 230fwhp or so with headers and good exhaust. That package would be a very very mild combo. Perfect for someone who wants a nice daily driven package. As far as performance, the intake of choice is the Edelbrock Performer RPM. I have that carb and I like it. Most prefer Holley though. As you should if your intentions are most power and tune ability.

Didn't see it said swirl. Quickly glimpsed over it. I figured for the price they were probably swirl ports but with the vague cam information the only shot it had of making anywhere near 300+ hp was with a real set of vortec heads.

If you're going to pay a shop to do all the motor work for you than just buy an assembled crate motor. It will be cheaper in the long run... and some crate motors have pretty good warranties on them.

the engine Vetteoz posted is what i was asking about?? would anything from the lg4 transfer over to it? or lg4 stuff just a waste??
Actually, the '99-'01 Vortec 350 full-size half-ton van engines were slightly better machined, and if you aren't buying new aftermarket valves, these flow slightly better on the exhaust side, where the Vortecs need all the help they can get. 1-ton engines had more emphasis on durability than power, so any year Vortec heads can have the worst-flowing exhaust seat angles, and need 1.6" valves to fix. But they're still the same casting numbers. You must pull the valves to see what you really found.

If it's a swirl port set of heads, no way in hell in any scenario they are making 325 hp.

I'm about done assembling a true 325 HP motor , reusing the rotating assembly (polished crank, new bearings, rings, etc) I'm in it for about $2,200. I had the long block (vortec heads) laying around. Only labor I paid for was $800 in machining on the heads, valve job, mag/polish crank, install new springs/retainers/locks/seals/guides. About 9.2:1 compression; took a 224/230 duration .502"/.510" cam to get there.
You're 50 horses short. Something's very wrong. And getting a 9:1 swirl-port 350 to 325 HP with no power adder isn't that hard. It just takes a huge cam, a decent intake manifold, and headers. The catch is that you'd hate trying to drive it.

Blue Print makes some pretty descent stuff. These are fully assembled and can be dropped in the day it arrives for $3,800-4,200. They are also backed by a 30 month 50,000 mile warranty if I recall correctly.

If it is a late model block you can't fit a mech fuel pump ( without drilling holes )
Easier to use a elec pump

No, it drives awesome. Just a top end kit, cam, intake, carb, timing gear set, and new fuel pump to feed it.
Hasn't been dynoed yet but,
Messing with a friend in a dyno tuned 345hp stroker Mustang, stock I watched stangs tail from start to finish. Now with my motor done he'll never see my headlights again. Haha.
Not true buddy, (I still have to pull up to your house)

I don't consider a motor that is engine dynoed with no accessories and dyno headers as a true XX hp motor. The way it sits in a vehicle with full exhaust is how I estimate my power numbers. I could lie and give you guys a comparison to a crate motor and guess around 375/440.

Fully dressed I doubt it would break 350 horses and I'm usually conservative on output.

Re: lg4 to orange block 350 with 325hp

Youre better off with that engine vetteoz posted. It has a roller cam. That's a big advantage.

http://www.jegs.com/i/GM-Performance...oductId=813788

You can piece together a whole carb setup for probably $500 if you look hard enough. Re-use everything else you have already and you're good to go.

If you put some beehive spring in it you can spend another $300 or so and put a roller hotcam in it (spend another 250 and get an XR276+better springs and it's 375hp) and hit 325-350hp.

That's still significantly less than the engine you posted, which doesnt even have a roller cam.

Re: lg4 to orange block 350 with 325hp

to many choices.. for engine in your posts what would be best distrib, whould long tube headers be better? what if i went with top end kit (carb,cam,lifters,rockers,intake,heads)

in all honesty id like to purchase a turn key engine, take away all the guess work out..
something more of a (drop in) deal

If you reallly just want to drop something in, go ahead and go with the $3999 motor. It'll have a warranty so it makes it easier for you. No risk of valvetrain mistakes in setup. You may still need to change out the water pump though, depends.
