I found this list --------------------------------------------------------------------------------

Available mods for the GM 3400 engine





This page contains a list of all the available modifications for the GM 3400 (LA1) engine and where to get them. Because the parts list for these vehicles is growing every day, this list will always be incomplete. The vendors listed here have the right to change any prices at any time so the prices listed are estimates. Horse power estimates are based on our "best guess" and will not always be accurate since many mods depend greatly on what supporting mods have been done and not every mod has been dyno tested. If you have any questions about any of the mods on this page, or some more mods to add to it, email Jeremy or Kevin.

lot more mods for the v6 than i thought!

Turbochargedpower.com's 3400 turbo kit has been under redesign for over 6 months, I doubt they are going to have one anytime soon.

There's more than that.

does anyone have a GM build book for the 3400?

Agreed.

I guess now the swap is out :rolleyes2:

no i'm going to go talk to the guy to see when he can do the job he has an alero in his junk yard to use as a gig to fab the parts so i won't have to use mine. it will give me time to find motor ,trans .ect

That list is old and inaccurate. Where did you find it? Level 5..I want level 6.

clubgm.com

No such thing. This isn't a 4 cylinder Ecotec we're talking about...

60degreev6.com is the closest to a build book you will get that I know of. The published books are for the older motors and won't help a heck of a lot. Some of the tips/tricks work but most of it is not relevent.
