i saw a post earlier but it wasnt answered, is there one for the 3400?

 

There's probably not one of those for a 3400, I'm not sure though. Look for Grand Am performance websites. GA's have 3400's, so I'm sure their parts fit your engine. (Perhaps with the exception of headers, you may need to modify your firewall or something)

 

everyone skips right over the new guy!!!!!!! :P jk

 

Honestly, its not really that- its just most of the knowledge base on here is people with 3800's mostly, and to some extent LS4's- not a whole lot of people that are real into modding the 60* engines (3100/3400/3500/3900)- and the ones who are don't post much.

So it isn't really that I (or the others) were ignoring you, more just that we weren't sure about the 3400 engine specifically.

 

just messing around bumpin' before i joind up and i wandered around the site and i know you guys aren't a*$holes so its fine. i knew what i was getting myself into

They have a test section but it was for the first gen HVII. Still good info to look at.

 

For the record, the 3400 has no intake inserts. It's strictly an aluminum intake and the passages are already there. What people do with the 3400 is the install a 3500 upper intake manifold, but that takes a few modifications to do.

 

so basically i'd be better off upgrading to the L67 or the 3800

 

No doubt

 

the flex fuel fuel rails and injectors are biger than the stock ones and also a few different sensors as well. there are some headers out for the 3500 engine as well as a biger cable driven throtle body
