Decision on a new engine..........

Well its time to start saving so I'm looking around at new engines. This is about the price range I want for the street engine. Just about 3 grand tops to get it in the car and running with 330 HP or more. The 350 sounds good, not sure about the 400 anymore. The computer has got to go. I'm not deal with its shat anymore. Its like a nagging woman, My sensor is bad FIX IT! The motor runs just fine its just the ECM that is a load of shti. Anyway here is a 330HP\350 2,222.80 The rest of the parts I can pick up here and there but here is a link.

Hmm, If I'm not mistaken those are decent heads, and if you don't mind voiding the warranty, just port them to flow a little better.

The thing is I have had these bad *** heads laying around that would flow like hell. But I dont know they might be too extream for that motor setup.

You must be able to pick a really well rebuilt 350 shortblock for around $1000 US. Then just transfer over your current parts to complete the engine. $3000 for an engine only pushing 330 hp is a LOT of money.

Use your imagination.

Well, I got my GM Goodwrench longblock for $1290 and it is 4 bolt main. The cam in it sux, so that would have to be changed. The heads aren't the best either, but can be ported to flow decent, for some power. Though do shortblocks come with heads? I thought they did.

Short blocks don't include heads. Long blocks mean the heads are included.

If you can't find a really good 350 freshly rebuilt shortblock then you haven't even looked. ANY place that rebuilds engines can supply you one for that price.

Mark that 350 you got for 1295 sounds like the same one i got from GM, everything brand new..includes everything except flexplate,intake,exhaust, front access and carb... I put that same engine in my 70 Camaro cause i was a on budget and couldnt get like a ZZ4 at the time, but i swapped in edelbrock cam/lifters/carb/intake/headers/hi-vol oil pump/double roller timing chain/hei distrib from a 79z28 w/ accel parts, im thinking of getting the performer heads and the edelbrock TPI setup for it later on, but it runs great and has a good amount of power right now.

Good grief!

What on earth do you think you are buying? You could easily find a great rebuild for that money. Probably even less.

So Redbird_400....if you're not sure about the 400 anymore, does that mean we'll have to call you Redbird_350 from now on?

What I mean is How much HP can you push out of those parts for that price?

It might run or it might blow up they just give you 30days.

Well, you get a shortblock. You know, the block, crank, pistons, cam, etc.?

Your hp comes from what you surround that with. Assuming you can ask them to build the short block with 9 or 9 1/2 to 1 compression ratio, assuming a certain size of combustion chamber, your hp will then only be limited by the heads, cam, intake, headers, yada, yada, yada ...

Go read the recent Hot Rod mag where they have the 3rd gen Formula on the cover. That guy has his stock 89 350 L98 short block running 10s in the quarter mile.

This is no great mystery. Your hp and torque are merely the sum of your parts! It is only when you want to start turning more than 6000 rpm that a standard rebuild will be lacking.

You just want to be sure they are using standard quality parts. Hypereutectic pistons, resize the crank journals and rod journals, use the proper size of bearings, align hone and deck the block, etc. This is standard fare for any reputable rebuilder.

My personal rule of thumb is that a small block Chevy makes a nice reliable daily driver when it is pushing 1 hp/cubic inch. Beyond that, it starts to become iffy. Thus a 305 pushing 300 hp makes me happy and I can count on it to get me anywhere. Same with a 350 hp 350.

I'm sure others will disagree.

What do you want?

Help me understand...

Your computer control system gives you fits, so you're going to downgrade your short block???

Why not do away with the stock CC components, freshen up your 400 short block if necessary, put a set of decent heads on it, and a cam and intake and carb, and enjoy the 50 more CID? You will be buying a set of heads either way; you'll be buying a carb, intake, cam, etc. either way; you'll be either buying a new built short block, or repairing your old one (I think I know which one is going to cost less); what benefit do you get from using your own money to start out with what you now have and end up with less than what you have now?

Those are used engines. If you are on a budget and don't mind taking a chance, go for it.

But if you want to do this ONCE, and then drive it without problem for 150,000 miles or more, spend $1000 and get a good rebuild. In fact, I'm sure you can get one for less than that.

Check out this link:http://www.mooresengine.com/machineshop/index.html

This is a rebuilder here in Calgary but these type of REPUTABLE rebuilders are all over the continent. This will show you what a good shop will do when rebuilding a shortblock. Then check out the price and knock off 1/3 for a comparable US price.

http://www.mooresengine.com/engdescript/chev.html

A LOT less than you thought, eh? I put 400,000 kms on a 350 rebuild I bought from these guys.

Even if your heads are shot and you have a phobia of rebuilts, do what Mark Shields did and get the GM Goodwrench 350 for $1300. That includes heads, etc. Chevy Hi Performance did a nice buildup of precisely that engine and pumped out about 425 hp with bolt ons. It is on the web starting here: http://www.chevyhiperformance.com/ed....jsp?id=46320& viewtype=text

But why bother when a rebuilt is just as good and CHEAPER?

However, you MUST tell us what is reuseable on your current engine. Then you can get some GOOD advice

400s are very streetable engines. I can drive around all day and never go over 2000 rpm, and with my gears, I can do about 65 in OD at 2000. As a result of this, I manage to get about 17 mpg in the city and about 20 on the highway. The only problem is my current engine setup sucks with a 700R4. It is too hard to stay in my power band. But once I get heads, cam and headers, this problem should be solved.
