Re: Mods for 350

The B&M pro ratchet shifter is a nice piece. Also you should make sure that your shifter cable is routed properly and it is rigged to go into each gear.

There might be a few Neons out there but this is mostly a 3rd gen board.

Either way there is a lot of info about upgrades Here

Have you ever considered reading what you typed before you clicked post?

Rear end gears, true dual exhaust, turbo, supercharger, camshaft, heads, intake, nitrous, weight reduction, full suspension, 383 kit, etc. There. A list of mods, which is what you seem to be begging for. GIVE US SOME CRITERIA AND PARAMETERS TO WORK WITH BEFORE GIVING AN OPINION

Re: Mods for 350

You first mod should be getting your car running correctly including your shifter.

It would also be a good idea to post up actual details about your engine besides it came from Jegs. They have at least a dozen 350s they sell.

Looks like a flat tappet small block made between 1950s to 1986.

Got any casting numbers for the block or heads?

Re: Mods for 350

most of your post's are confusing. I agree with the post above and getting your car running and figuring out what is wrong with your shifter. What exactly do you even mean by mods anyways? Be more specific with your questions and i am sure people will be more apt to give some advise on different items.

OK sense it looks like you tried on this post I will help you a little.

You want to know about "mods", mods for what? Specifically the engine?

Well you could do heads but then we run into an issue.

Do you have good heads? We don't know because you wont pull off the valve cover and look at the casting numbers.

Do you have money for good heads? Again we don't know because you never stated a budget.

Are you heads good enough for your power goals? Again we don't know because you never stated a goal.

Maybe you could install roller rockers.
Do you have roller rockers?
Have you looked?
Would 1.6 rockers be better with you cam?
Do you know what cam you have?

Maybe a cam swap that is a mod.

Flat tappet or roller block?
Would you be willing to spend the money for a roller conversion?

How about twin turbos? Budget? Skill?

Are you starting to get the picture? We know nothing about your engine and there are over 100,000 combinations of parts that can make a SBC V8. I could create a massive list of possible mods but why type that when I don't even know what is under the hood and what would be helpful.

You could have a crappy low compression 200hp V8 or a nice 400hp V8. We don't know all we have are fuzzy pictures with no detail. At least get some casting numbers and report back.

Considering you did not even take the time to turn the pictures right side up you should probably be happy with any info given

Probably the cheap 260HP version

But as they all look the same it is hard to tell anything besides the fact that it is most likely flat tappet.

Which means use a decent oil with some zddp

Saying you a jegs 350 is no different than saying I have a 350. They sell dozens of them from different manufacturers and different specs.

We cannot tell you were to start because we don't know where you are starting, where you want to go or what resources you have to get there.

You are basically asking how to get to Disney without saying which one or where you are starting from. Could be across the street could be Easter island. Are you going to swim, drive or fly?

Right now all I can recommend is reading. learn about the engines and how to identify them.

Buy these books and put the on the back of the toilet for reading. If you are learning too slow get indian food and try again.

Probably RTV on the gasket. Tap it with a piece of wood or RUBBER hammer.

Ouch but at least it is a start. Better go buy those books and some tools. There is really nothing more you can do to bolt on easy power.

The dished pistons kinda suck for anything performance and the compression is really low for any decent cam.

You could probably get away with a mild cam and head swap for about $1200 in parts and make a bit over 300hp. Make sure the heads are 62-67cc. DO NOT GET PROCOMP HEADS.

If you are looking for easy thing get some roller rockers. 1.6 if you want to but make sure you take that into account for any future cam swaps.

Have your front end checked out, make sure the ball joints and other suspension components are in good shape. Also have the alignment checked.

Personally I would get the suspension up to code then work on the engine.

If you go any decent cam you will need a new stall.

That is a Scroggin Dickey goodwrench 350 with a xe268 cam. You do not have that.
The XE268 is worlds apart from your cam.

Re: Mods for 350

You may have that engine....but 500-700$ in bolt sons is not gonna get you 400 HP to the wheels. Which I'm assuming is what matters to you. That's why your suspension should be gon over 1st. How are your strut mounts?..because the factories aren't the greatest brand new.how about frame connectors? Less body flex will make your car FEEL a lil more powerful....do you have a wanderbar ? Do you know what that is and what its for? The factory panhard bar is VERY flexible. And you will for sure need that to keep your rearend under control @400hp.....and with shipping that's most of your budget rite there. Those parts will give you more satisfaction that buying a 400.00 intake and roller rockers...which will be the top of your budget n you still haven't paid for shipping....there plenty of threads of guys on here asking the same questions, not listening to the advice and buying half the parts out of a tech article next to there toilet and expecting the full results....baby steps man...gotta crawl for you walk n all that stuff people hate to hear, If you don't have 5k to start with

Re: Mods for 350

Idc how much hp I thought it was a good article id b fine with 300 hp I just want a good dependable car that will last. I'm not aiming for fast &furious id rather put mods that will help my car last I want to have good handling n I need to do some minor stuff like headlight repair kit ebrake cable a/c unit and a radio then I gt couple dings on the left fender I whonder if I can get one painted and my hood needs to be painted too that's probably a good $500 right there but id like to put in some minor things to better handle the car

Not good that you don't see the problem. The cam and heads are where all the power is made.

We already told you what to do next. Get some books, read them and save money. The cam and heads are where the power is made. What you have besides them is just a low compression shot block with dished pistons. That is like saying I am exactly like an Olympic athlete minus the heart and lungs.

Learn about cylinder heads and cam profiles. Learn how the work. Then save money.

Also you seem to be forgetting that going vortec requires a different manifold, valve covers and rockers so you are missing more than you thought.

Please for the love of god please type entire words.

unfortunetly, those are some of the worst heads for performance. known as "882's" 76cc, open chamber=low compression when combined with dish pistons.

a set 58-64cc heads would be a huge improvement for power.
add a decent cam and you'll be in the right direction. too big of a cam and you'll need a different converter.

do you know what rear gear you have?

We cannot tell you were to start because we don't know where you are starting, where you want to go or what resources you have to get there.

You are basically asking how to get to Disney without saying which one or where you are starting from. Could be across the street could be Easter island. Are you going to swim, drive or fly?

Right now all I can recommend is reading. learn about the engines and how to identify them.

Buy these books and put the on the back of the toilet for reading. If you are learning too slow get indian food and try again.

Re: Mods for 350

well, that's why the guys are telling you to do some research. take your time before you go buying stuff randomly. vortec heads require a vortec intake manifold. in stock form they're only good to about .450" lift before interferance issues between the retainer and seal. theres just too much to write. google vortec heads, you'll see tons of info. gotta do your homework.
same thing with selecting a cam, do LOTS of research. knowing your rear gear ratio is important to selecting a cam, along with many other things.

If you can't figure this out, you shouldn't touch a motor, so that brings your budget down as we now have to factor in labor. Maybe you should just get an air filter or something. Spend the rest on grammar lessons so you no longer come off as a dyslexic monkey banging on a keyboard.

Since your having reading comprehension issues, I compiled this for you......

Personally I would get the suspension up to code then work on the engine.

Less body flex will make your car FEEL a lil more powerful....do you have a wanderbar ? Do you know what that is and what its for? The factory panhard bar is VERY flexible. And you will for sure need that to keep your rearend under control @400hp.....

That takes care of what you "should" do first.....

If the car runs good now, LEAVE the engine alone and work on all the above that other's have suggested per YOUR request......

Once you have completed all the needed repairs/upgrades to make it handle as You say you want and look good as you want, Then work on upgrading the engine. But..... Keep in mind, On a daily driver, The more you upgrade a engine the worse fuel mileage will suffer. So in the end, It will cost quite a bit to make this engine what you want and will continue to cost at the gas pump......

Re: Mods for 350

Again...... Leave the engine alone for now and work on the rest, There will be other deals down the road when you get to that point.

Upgrading a engine in a sloppy driving car is stupid at best......

Re: Mods for 350

After a bottle of quervo and a 12pk I'll try to help 1 last time....yes you can make power switching heads and cam...question...what type of automotive work have you done? N after 3 fbodys why don't you know any of this? Can I suggest smokin a joint on this forum? How bout wwoooohhhssaaahhhh....You missed every car part I suggested and went straight to hostility...which tells me you aren't very perceptive... which is gonna cause you problems when trying to change these parts, PERCEPTIVE...I'm sure you could see rtv around the edges of the valve cover...you never thought...hmmm that's weird there supposed to be a silicone gasket there....you have to think like that when "MODDING" these cars...if you don't know what type of can and lifters are in that block how are you going to set valve lash when you reinstall the heads??? Don't get mad...think about it.....if you set them like hydraulics and they are solid flat tappets...there goes 100 bucks real fast....and your good running engine is now a shelf until you replace....what??? Don't get mad....answer the question....I really am trying to help you get your gears turning before you are looking for your 4th fbody. I watched a guy changing his cam for the 3rd time because "it was such a bad *** race motor" and tap his #8 exh lifter in with a hammer because it wouldn't drop in....fu***** genius he was....that's another thing...have you installed a cam before? The last journal is....more difficult than over coming rtv to say the least....have you read about can bearing wear patterns? Might wanna check into that....for 500 buy a drop out lt1....don't do anything to it just read about wiring and fire it up....I don't give a **** about vortec heads so I don't want to offend any 500hp builds here when I say "theoretically" that should net you more power than vortec heads and can will, plus efi....do you know what I mean by efi? (Just tryna get you think in) will help with early morning starts in 10° weather and keep your neighborhood happy @ 6am....just a guess but I feel like your the cherry bomb, glass pack type....yes I'm a lil judgemental....but I'm sure you've spent a night _______ and woke up __________
Cheers bro

sure, why not? You sure as fvck aren't listening to anybody here anyway, so yes, you should def. Get them. Even though you can't figure out rtv, you're DEFINITELY ready to change heads.. on that car with the worn out suspension.
