Ok, so ive been readin on how the most recent 3.4L is a bored out 3.1L (if im reading correctly..
LA1

The LA1 3400 was a bored-out version of the LG8 (http://en.wikipedia.org/wiki/LQ1#LG8). It retained the OHV (http://en.wikipedia.org/wiki/OHV) layout of the previous engine, and was first utilized on the 1996 U platform (http://en.wikipedia.org/wiki/List_of_GM_platforms) minivans and appeared in a car for the first time in the 1999 Pontiac Grand Am (http://en.wikipedia.org/wiki/Pontiac_Grand_Am) and Oldsmobile Alero (http://en.wikipedia.org/wiki/Oldsmobile_Alero). A 92 mm bore brought the displacement to 3.4 L (3350 cc). Like the LG8, the LA1 featured numerous common parts with the similar GM High Value engine (http://en.wikipedia.org/wiki/GM_High_Value_engine) family. Power was up to 170 hp-185 hp (127 kW to 138 kW) and torque was 210 ft·lb.






Now, does this same method of manufacturing apply to any of the 3.8L engines in the GTP's?



IE: Would there be any possibility of using GTP parts on a RWD oriented 3.4L pushrod 60 Degree V6, Mainly...

Just curious...

EDIT: IM assuming the RWD 3800 is a completely different motorfrom the FWD 3800 and no parts are interchangeable..

Suposedly a 3.1 is a bored 2.8 and a 3.4 is a bored and stroked 3.1. I may have that backwards but they are in the same family. You can get decent HP out of them in a light car but torque seems to be unavailible. GMPP used to have alot of perf. items for them. You can still get Edel. intakes and other items. I used to see a turbo kit for the Beretta back in the day.

all's i know is that until 3000 RPM the 3.4 is a dog. it has no low end power. my wife has one and i hate driving it cause it is not near as responsive as my truck on the bottom end.

The 3800 is a 90* v6 and shares nothing with the 3.4. The 2.8/3.1/3.4/3.5/3.9 are all 60* motors on the same architecture.
