Would this be a good engine for a 87Gt Auto? I have looked on here and can't find much info on it. If it would be good what all would I need to get? Any and all thoughts, info. appreciated thank you.

Pretty sure those are VVT motors which would be more work than its worth. The 3.5 you want would be out of the Malibu. Would need an external crank trigger and throttle body and adapter among other things to get the LX9 running.

------------------

87 GT: Need to get road worthy first
92 Cutlass Vert: LX9/20s/tons more
01 Impala: Wifes taxi
99 Blazer: Parts hauler/winter beater

A 2007 Impala will have an LZ4 VVT 3500... that is going to be quite a bit of screwing around with cam phasers and the like...

What you are looking for is an 04-06 3500 out of a Malibu, Aura or G6 or one of the minivans... that would be the LX9, if you are looking for a 3500. No VVT to screw around with.

You'll need an external 7x reluctor and a throttle body adapter (LX5 3.5L Short* V6 throttle body) to run it with the ECMs most people use for swaps...

If you don't want to screw around with that, look into a 2000+ 3400 run off of a '7730 ECM. The 3400 is a cam away from the same power level as the 3500.

Hope that gives you a good starting point!

Or stick with the fly by wire and use the stock ECM/TCM and get it reprogrammed to remove the VAT's and retain the VVT

What is the WT that you are talking about? This is a link to it on e-bay and it is very close by:2007 CHEVY IMPALA ENGINE 3.5 V6 I am also confused by this here at wikipedia GM High Value engine LZ4 : " LZ4[edit]

The LZ4 3500 is an OHV engine based on the 3.9 L LZ9 V6. It was introduced for the 2006 model year in the Chevrolet Impala and Monte Carlo. It includes continuously variable cam timing (fixed overlap). It has a cast iron block and aluminum heads. Output is 211 hp (156.5 kW) at 5800 rpm and 214 lb·ft (290 N·m) at 4000 rpm. Bore is 99 mm (3.9 in), stroke is 76 mm (3.0 in) for a displacement of 3510 cc. Horsepower rating changed for the 2007 model year to 224 hp (167 kW) at 5800 rpm and 220 lb·ft (298 N·m) torque at 4000 rpm. The Chevrolet Malibu, Pontiac G6, and Saturn Aura became equipped with this engine for 2007 (previously the Malibu and G6 had the non-VVT 201 hp (150 kW) 3.5 L LX9). In 2008 SAE ratings dropped the horsepower ratings to 219, keeping torque as is. On Pontiac G6 convertible models, horsepower was rated at 217.

Applications:
2006–2009 Chevrolet Impala
2006–2007 Chevrolet Monte Carlo
2007–2010 Chevrolet Malibu/Chevrolet Malibu Maxx
2007–2009 Saturn Aura
2007–2009 Pontiac G6
2008–2009 Saturn Vue XE AWD (222 hp/220 lb-ft)

Note: GM often refers to this engine in its literature as a "3.5L V6 with Variable Valve Timing".

LZE[edit]

The LZE 3500 was an OHV flexible fuel engine based on the 3.9 L LZ9 V6 (it can use either plain gasoline or 15% Gasoline and 85% Ethanol, E85) and includes continuously variable cam timing (fixed overlap). It has a cast iron block and aluminum heads. Bore is 99 mm (3.9 in), stroke is 76 mm (3.0 in) for a displacement of 3510 cc (214 cu in). Output is 211 hp (157 kW) at 5800 rpm and 216 lb·ft (293 N·m) at 4000 rpm.

Applications:
2006–2011 Chevrolet Impala
2006–2007 Chevrolet Monte Carlo
2009-2010 Chevrolet Malibu
2009-2010 Pontiac G6

These engines should not be confused with the LX5 "Shortstar" DOHC V6 used in the Oldsmobile Intrigue from 1999–2002, which also displaced 3.5 "

Which motor is this at e-bay?

V V T = Variable Valve Timing

2004-2006 LX9 3500 201HP - Like a high output 3400
2006-2011 LZ4 3500 220HP - Has variable valve timing

1999-2002 LX5 3.5L DOHC - Oldsmobile Aurora engine. Completely different beast based on the Cadillac Northstar.

The engine in that eBay listing is the LZ4 3500 VVT.

Thanks to you all that have replied. Carbon here's a for you. Thanks for the links and info. That did help me understand things better! Imight want to keep looking.

might be able to retain the VVT, and use a cable throttle before long using a 7730 and $nAst1. I've been keeping my eyes on the progress, could open quite a few doors for us.

I would just install it as is and keep vvt and dbw. I wouldn't mess with trying to downgrade it to obd1.

I have a G6 with the LZE. I think it would be a lot of fun in a Fiero.
I think that the 3.9 may have been available with a manual tranny, but I'm not sure.
It might make a good base for the 3.5 with a manual.

I just hate dbw, I would consider just about any option to avoid it! but that's just my preference. when I have more time, I'm going to look into programming a 3400 PCM to control VVT.

The DBW parameters are fully programable and you can set them to act just like a cable driven throttle. I jump between 4 cars and only my LS4/F40 is DBW and I can't tell the difference. My preference on swaps going forward is to use DBW anytime it is an option.
