For the better part of a year, I have been fully engaged in the complete tear down and rebuild and performance upgrade of a 1995 GM L-32 3.4L OHV RWD V6 engine. I have been trying to faithfully document all phases of these procedures in digital photographs that I have saved for public consumption on the following image warehouse site:

The Stock throttle body is only 52mm in diameter. This is hardly enough space to suck in the air this motor needs for peak performance. This unit is 62mm in diameter, and is a much better design than the stock peice. Note that this is NOT a stock throttle body that has been modified, this is a COMPLETELY new peice machined from billet aluminum.

The 3100 and 3400 engines are called Gen 3, because they are the third generation pushrod 60V6 engines. The reason for the swap is simple. Flow and design, both of which the gen 3 triumphs all previous gens. The iron heads don't have splayed valves, D shaped exhaust ports, or in some cases even the larger valves (1.42/1.72). The Gen 2 Aluminum head engines are the most popular to do this swap, but no matter what you start with, the same steps apply.

Easy way...use a 3.4 DOHC windage tray, otherwise have fun doing it this way.
Parts you need:
7 - 3X00 Main cap bolts,
7 - 3X00 Windage tray nuts
1 - 3X00 Windage tray. (GM calls it a Crankshaft Oil Deflector)
Its a fairly simple mod, Easiest if the engine is Out of the car so you can have it on the stand and upside down to work on the bottom end.
Obviously, Remove the Oil Pan.

Stock pistons for the NA motors weren't designed for boost. You can use nitrous in moderation, using a 50-75 shot, but you will need to make sure hte tuning on the motor is up to par for such an upgrade. If you want to play it safe, it is best to upgrade the pistons to either the TGP version or aftermarket hyperutectic or forged.
