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.
