330 hp and 380 lb ft, is this able to run low 13's. I've seen times of high 13's, but with good traction and good tuning can this engine pull off low 13's. I like the engine, like the ZZ4 more but the 350 HO(330/380) is more in my price range... then again you get what you pay for.
Thanks Matt.

Also what do you guys think of this engine, is it pretty durable? I looked at a parts list and it looks decent, makes good power.
Thanks.

 

It's the most popular performance crate engine GM sells. That should tell you something.

The HP #'s are with carb, long-tube open headers, etc. The induction you use will affect performance. If you want to put a bigger cam or the like in it, you'll need better valve springs (probably a good idea anyway).

 

It's a 4 bolt main roller ready block (1 piece rear seal) with nice heads for $2000....it's an awesome deal. Great motor but I wouldn't put any power adder on it. Keep in NA and it's capable of running low 13's depending on traction, tuning, and weight of the car. If you got your car down to 3400lbs without you, had a decent exhaust system with headers and slicks with posi and 3.73 or 4.10 gears the car could be really low 13's maybe even high 12's if you get crazy.

 

I would like to this swap but I have to pass a sniffer test. How, if at all, do you route the EGR. Does anyone have a diagram or pics of the external routing, i.e. corvette or vortec truck?

 

I passed the sniff test in NJ with the dyno and at a state inspection center. I even had a visual inspection but I have NO idea how I passed that one.
EGR helps but this engine is clean enough to pass emissions testing even on these darn dyno units, I'm proof. All I had was a cat converter, no air pump and no EGR. I only had problems with my Nitrous fumes because my thermo was broken and the heads were cooking.
goautocenter.com and a few other places sell external EGR intakes and plumbing. I think the intake manifold was something in the ball park of $300 and the EGR pipe going into the header was an extra $50.

 

My local dealership here in Connecticut has one of the 330hp crates in the parts dept. Someone ordered it and canceled after the dealership had it delivered. They are looking to dump it for $2100 I think. I don't know if that helps. If you want more info e-mail me.

 

Thanks Prevost, as a matter of fact I also have the dyno sniffer. Didn't i see in one of your other posts that you were thinking about the "HOT" cam? When do you plan on doing it and do you think that will cause any probs with you passing emissions? I have 185k miles on my LO3, and I know it can't last too much longer so I'm trying to decide which 350 to install and whether I'm going to stick with the stock TBI or go with the Holley. I am concerned with the emissions though because I would hate to spend $3-4k total (engine plus other stuff), and not be able to pass. How hard was it for you to tune a chip for this engine? I would like to keep a roller setup and I know the HO350 isn't, do you think the 97 LT1 cam I have would give me a few more ponies or would I be sacrificing some of the HP to go with that cam? Thanks again.

 

The hot cam will definatly not pass emissions. It would take EGR and some fancy eprom tuning to get it to pass. I plan on slapping in a factory Lo3 to pass emissions tests. Since it's only once every 2 years I figure it'll be worth it. The engine swap isn't difficult. You can reuse the fluids and the engine will bolt right up to the tranny with 8 bolts and 2 on the engine mounts. If you can get access to a complete Lo3 with TBI then it's a matter of just slapping the thing in there and driving it over to inspection. With good hands and a dedicated bunch of friends it's possible to do this in a day.
As for the Lt1 cam, you'd probably give up just a few ponies compared to the 212 222 cam. The Lt1 would have no problems passing the sniff test. I'd have done the swap if I had the time and the roller cam...but I didn't. Oh well

 

Whoah, wait a second. The Hot Cam should pass in a New York minute. If you want to talk about a cam that will be hard to pass, try mine...... 235/242 .568/.592 114 on an engine that runs cool.

Its going to take lots of dry gas and a quick upload of a program to keep the engine running a bit to the warm side. I'm going to have a tough time passing. LT4 Hot Cam though? I seriously doubt it. That thing barely has a noticable lope to it. GM wouldn't be selling them in the numbers that they have if they were not emissions friendly.

Go to Camaroz28.com and do a search in the LT1 and 3rd gen sections on the cam.

As far as GM engines that will pass emissions and make power for about $4k.......I can get the ZZ4 for $4400, Fastburn 385hp for $4900, or for a little more $$ I can get the Ramjet 350 which will dump right in - give it spark and fuel and go - for $5500 or so.

Any of those engines will do the trick. Take the fastburn 350 with 385hp and add the Hot Cam and it makes 430hp. Then you would have a ZZ430, just without the snazzy valve covers.

 

Man, I don't know what you've been smokin', but keep it away from me. I prefer a clear head.

I was with you on the Hot Cam discussion, but none of those engines is a "piece of cake", emissions-wise. None is EGR-friendly as-is, although the ZZ4 can be externally plumbed. And a RamJet 350 would "dump right in" and pass emissions? Get real! Try that here, and they'd laugh you off the smog test lot - if they didn't arrest you on the spot, that is.

Okay, they wouldn't arrest you, but no way an open-loop system is going to cut the mustard. A ZZ430 may make it if you have the rest of the emissions system installed and completely healthy, including EGR. But, you're in for a tussle getting it to work properly.

A hot cam'd 350HO with EGR plumbing (and valve spring replacement - oh, roller lifters, too) would be much easier. But, hardly a "drop-in".

BTW, 1991 RS 305 never did say anything about emissions issues. Guess we all just wanted him to consider things he might not have thought of yet...

 

im thinkin about gettin the 330 hp GM crate motor as well-does anybody have a clue or a guess on how much Horsepower it would make with either a superram or the new stealth ram?thank you.

 

Thanks for all the responses. A crate 350 will probably be an option this summer provided finances continue to look good. I have decided that if I go that route I will defonatly get the 330 hp crate 350.

And here in Minnesota I don't have to worry about emissions, don't have em!:rockon:
