Hey everyone , I have a few questions that didn't come up in a search so I am hoping some of you can assist me.

I am getting ready for my winter project, what I am planning on doing is dropping a 440ci LS7 shortblock into my 05 GTO. the setup is going to be

440" LS7
* GM LS7 aluminum block w/ steel caps
* Callies Compstar 4340 4.100" stroke 24X (balanced to ¼ oz. in. tolerance)
* Callies Compstar 6.125" H beam rods w/ ARP 2000 7/16" bolts
* Wiseco 4.135" custom forged flat top pistons w/ LS7 VP's -3cc
* NPR stainless chrome rings 1.2 1.2 3mm (for reduced friction & high heat applications)
* Clevite MS 2199 H main bearings
* Clevite CB 663 H rod bearings
* Dura Bond one piece cam bearings
* ARP main studs
* Trickflow 235's
* Port matched Fast 90/90 w/ (**Optional NitroDaves MoneyMaker with a 200 shot )


Now I am going to have the engine built by LME since I have done quite a bit of lurking here they seem to be the company to go with. So here are my questions:

1- My car is currently fully modded and I currently have a tune on my car now when I drop the new engine in will the car run on that specific tune or will I have to get it tuned right there in order for it to run? I have HP tuners on order so if need be I can do it but I dont have a wideband.

2- The has an A4 with a 3800 stall and I have a goal of 500/500 N/A at the wheels will I have an issue reaching these goals? I have done quite a bit of searching and have not found this particular setup on an A4 so I am very curious. The car is a DD with some fun at the track every now and again so I don't want a real aggressive cam setup will I "need" that type of setup for my goals.

3- I'm also going to upgrade the tranny to a Perfomrabuilt Level 2 but I hear a lot of people go with the level 3 what is the difference between the 2? Will I still get the DD ability with a level 3 as I would with a 2?

Sorry for the questions if they seem off, but I want to have all my ducks on a row when I drop all this money, and I would rather do it right the first time.

Thanks

 

Anyone?

 

I would also post this over on LS1GTO.com....as they may be able to help you with the more specific questions. Many guys over there are running high hp cars with built trannies and stalls.

Free bump as well.

 

Thanks for the input much appreciated, but the questions aren't so much GTO specific, more so on the tune, and expected levels of power with the engine swap, and reviews on the transmission.

 

I was looking through your setup and I think your power goals are easily attainable. However, I would suggest rethinking your choice on heads. Are you going with those because you already have them, or are you going to be buying them? If you haven't bought the heads yet, I'd suggest running something that breathes deeper considering your cubic inches. I'm currently building 441 CI LSX with ported and polished LS7 heads. You wouldn't have to go that route, but I think a good set of CNC'd L92s with the L76 intake would do you justice and actually keep the pricing down.

 

Thanks for your input, I already have the heads and a new FAST intake, also what is keeping me from the L92/LS7 and L76 set up is the issue of it dying at 6500 rpms. Also I will be using the car mostly as a Daily driver weekend fun track car.

So you think those are attainable even through a stalled A4?

 

Obviously the A4 is going to put quite a hurting on your numbers. Also, what gear are you going to be running? That will also make a difference. I think you're probably in that neighborhood already assuming you're running a 3.73 or smaller.

Is the L92/L76 setup limited to 6500 even when ported and polished?

 

With my current mods I have (CB, CAI, LT's catted, 3800, Cam, FAST 90, PP TB) 445/395 NA at the wheels stock gearing, I have no plans to change the gears on the car. And yes the intake just drops dead for some reason at 6500rpms.

 

You shouldn't have a problem reaching your goals!Traver
