The 97 4T65 in the Monte Carlo is almost bullet proof. I have been beating the crap out of my reman with my blower now for 2.5 years of daily driving vs the 60 NA that I couldn't get 1 year out of. 4 Trans in 50K miles. I'm a violent offender.
Overfilling and royal purple atf are my secret.
DHP will do 96 and 97 DOHC tuning, HPTuners only works with the 97 computer. 96 can not change line pressure, 97 can.
97 bin is double in size of the 96 bin. They changed every thing and it has every table that the 97 GTP has, including performance shift mode that is disabled by default, but can be enabled. The 97 swap is an all around good thing.

by SchurkeyDug up the GM Service Bulletin for "Lifter tick when cold", 57-61-09. '91 to '95 LQ1 (VIN X) (mymonte.com is gone) The parts kit has been discontinued by GM long ago. My quest was to find sources for those parts; and complete the procedure on my '93 Lumina Euro 3.4 which was torn apart to replace the rear head gasket. There are three critical part numbers in the GM service kit (aside from gaskets and O-rings) required to perform this operation. Two of the three are readily available in the afterm...

by bszopiSeveral people have talked about the possibility to use the 3.4 DOHC heads on the 3x00 engines. Some for performance, and some for replacment, where getting a 3.4 DOHC block might be difficult, but getting a 3400 (or even a 3100) block might be easier to come by. For these test fittings, I used a 1994 3.4 DOHC BLOCK, a 1994 3.4 DOHC REAR head, a 1999 3100 SFI BLOCK, and a 1996 3100 SFI head. This article is broken into 3 sections. The first section is BASIC COMPARISONS where I compare the BLOCK o...

by SappySE107Here is the TRW catalogue spec sheet for the 91-95 as well as the 96/97 pistons....
TRW 3.4 DOHC Pistons
Silvolite 3.4 DOHC Pistons Notice that the 96-97 pistons don't have as much compression distance but also have a dome to them. I dont know the exact amount of compression loss you will get when using these pistons with the 91-95 heads, but it goes against the common belief that 96 pistons raise compression. The Silvolite pistons are the EXACT pistons used in the 91--

http://60degreev6.com/gallery/browseimages.php?c=27 Having just completed this swap myself and being MORE than impressed with the results, I felt the need to write up how to properly do this swap so everyone else can do it easily: First off, here are the major components you will need from your donor motor: Upper Intake (Plenum) Lower Intake and fuel rail ’96 Rear Cam Carrier Cover (Valve Cover) Intake pipe Throttle Bo...-
