Looking for any reviews and info on the Lingenfelter 670hp Edelbrock Package on a LS3 engine. I know it's based off the Edelbrock SC which I've read has great reliability and reviews. What about the LS3 ported heads and GT9 supercharger camshaft? Will these hurt reliability and everyday drivability?

Le Mans Z06

The blower cam helps you obtain more power out of the blower, ported heads would not hurt reliability or driveability. The more power you obtain, the less reliable the car becomes (To a degree....). If you don't want the camshaft or ported heads you can just do the s/c install by itself.

Ya I was debating whether or not to go with just the SC or go alittle further. Wanted to make sure it wouldnt kill street driving to have anything extra than the SC. thanks for the info

Then port the heads it will lower the Torque for better street driving.

Not sure I really agree that to improve street driving, I would suggest to somebody to port their heads. Porting heads will not result in lower torque numbers either on a FI car in all cases.

When your forcing air in to the L92 heads, I don't know how much difference it will make on the intake side. I think the exhaust side will benefit more from a little work and probably leave the intake side alone. I'm sure the experts can chime in on this.

OP, the GT9 cam has proven very good results on a couple forum members cars here. I'd ask around. There are quite a few guys with a lot of knowledge of PD blowers and specific cams to go with.

If it were me, I'd go with a centri blower. If you are set on a PD blower, I'd add exhaust and the proper cam, and leave the heads alone. Good luck.

I'd leave the heads alone too. LS3 heads are pretty good units as cast by GM. I can't believe the $/hp gained ratio is a very good one swapping LS3 heads. I wouldn't use the Comp Cams LSK lobes (which the GT9 uses) on anything. Too much lift and too hard on the springs. I'm sure you'll be told different and sold a very expensive set of valve springs. 247 duration .656 lift exhaust lobe? On a 670 engine hp (590 rwhp?) build? As much as I don't like the LS9 cam, I'd sure use it before using the GT9 cam. Better yet would be to have Pat G spec you one for your exact wants and needs. I'd bet that's not an option if you go with Lingenfelter.

Ya unfortunetly the package has to both add the GT9 and port the heads to achieve the 670hp number. Think is would be better to get a base package and then add a better camshaft for the engine and not port heads at all?

I overlooked the Comp Cams dual valve springs, titanium retainers, and 10 degree locks that come with the package. Would this solve the high lift the GT9 creates?

APSGTO

The GT9 cam makes huge power and have heard that it is very streetable despite the high lift. It will eat valve springs though. I would worry less about how the cam specs look and focus more on how it performs. 215/247 .629/.656 will throw red flags for most but Lingenfelter and several other tuners have had great results with this cam on LS3 heads ported or not.

The Linginfelter 670bhp engine package is a lot more then removeing the heads and porting them, replacing the cam and then slapping on a blower. It is a package that includes forged pistons/rods, plus other work to ensure the engine is reliable. Don't compare it with taking you car to a tuner/speedshop and having them do a cam/SC install for less bucks.

Where did you get this info? On their site it only listed half that stuff in the 670 package and the price is $13,995.

Nevermind your looking at the TVS2300 install. Im interesting in the E force 670hp install.

old motorhead

Yes, I'd get the EForce and a good exhaust (LT's and high flow cats if you must run cats). No way would I have the heads ported. There are lots of cam combo's out there that will out perform the GT9 and still play way nicer with your valve train. I'd bet the cam in my LS3 would do just that. 219/231 .607/.617 115LSA. The GT9 might catch it on the top end but I'd bet below 5500 rpm, there would be no contest. I know my valve springs are going to last longer.

Sure, those springs will last a while on top of the GT9 cam, but why fool with it? It's not making you any more power than a cam with milder lift numbers (and maybe slightly more duration). With a decent exhaust, there's absolutely no reason for a 247 duration .656 lift exhaust lobe on a build like this. Not for a minute saying it's not a great cam capable of great numbers.....just saying similar or better numbers can be had with a milder lift cam.

BTW: I've been making way more power than this for 2 years now with Maggie TVS, the 219/231 cam, and bolt ons. No, it's not a forged setup like JoesC5 itemized. If it does crater, I can then forge it and still come in way under the $22K for everything.

JoesC5

My bad. I looked at the Maggie engine instead of the E-Force.

Check the differences in torque. The Maggie setup has 630 lbs-ft and the E-Force 565 lbs-ft, with the same 670 HP. Don't know why the huge difference but it's the torque that is going to push you back in the seat on the street. They don't say, but the maggie might have lower compression and higher S/C boost since they use new pistons.

zero05

I see. Thanks for the info. What kind of Cam are you running? And which cam would you recommend for the base 600hp lingenfelter install?

old motorhead

My cam is one Pat G recommended for my setup. It's a Comp Cam ground by them using Pat G's specs with Comp's LSL lobes. I know just enough about cams to be dangerous. What works for me may, or may not be what would be best for you. I won't swap another cam without first consulting Pat G. He's not a sponsor here so I would suggest consulting him (he charges 25 bucks), getting the specs, and then using a forum vendor to order your cam. Most of the forum vendors are Comp Cams dealers. You can go direct to Comp Cams with your order, but you can just about always save a little coin going through one of the forum vendors. You save a little....dealer makes a little....everybody's happy. If you go direct to Comp, they will charge you full boat retail for the cam. I've seen dealers discount custom Comp grinds 10 to 15%.

APSGTO

I noticed that they don't have aftermarket long tube headers on that list. Might be why the GT9 camshaft is so aggressive on the exhaust duration/lift.

old motorhead

I've wondered that too. I'm betting the vast majority of the users of the GT9 cam on this board have LT headers though. I've seen some pretty impressive power numbers on builds using the LS9 cam. Isn't the exhaust lobe on that cam something like 230 duration with about .550 lift? With that cam, you can use the stock springs, p'rods, and lifters.....and probably never have to worry about a broken valve spring, bent p'rod, or collapsed lifter.

winters97gt

Yes, it is 230 on the exhaust. I'm guessing I picked up about 20-25hp with it when I added headers at the same time. I lost no boost with headers and the cam.

APSGTO

I've heard they both work extremely well with the L92 head. I'm betting lingenfelter wanted to keep there packages Carb friendly by keeping the stock manifolds.

zero05

For the same money would i be better off going with the 630HP TVS2300 SC package from Lingenfelter? This one?- http://www.lingenfelter.com/engine-p...0-supercharger Would i be able to still use this hood - http://rpidesigns.com/shop/item.aspx?itemid=1577

thanks

old motorhead

I'm missing what you get extra on the 630 hp package over the base Maggie package. Where's the 3 grand? How much power does the base package put down? You'd have to ask Lingy about the hood. You're already paying for one on both packages.
