Dirty Rockstar Posted February 3, 2007 Report Share Posted February 3, 2007 Well, my car has 161k on it, and I am starting to think about the intake gaskets.. Since I have to tear it all down anyway to do these gaskets, I am more and more tempted to get the 3400 intakes and heads.. They're popping up every so often in my Upull yards, and I dont have a concern with pulling them if it will net me some more power.. ..What are some concerns with it? I know Brian has done both the heads and the intakes.. What should I watch out for if I do this? I know the 94 3100 doesn;t have roller rockers.. Will this be a concern? How many different style intakes were on the 3400s? I want the biggest TB I can get along with Plenum port sizing.. I know in 00 I believe, the 3400 and 3100 intakes were the same, save for the casting on the top.. (3100, 3400, blank..) Were they the same size when the 3400 first started hitting the Vans? (Montanas, Silhouettes, etc..)? ..If I have anything else I need to know, I'll throw them up here.. Thanks in advance guys! Quote Link to comment Share on other sites More sharing options...
Crazy K Posted February 3, 2007 Report Share Posted February 3, 2007 I am going to attempt this on a 94 3100 later this year. The pedestals for the rocker were enlarged in 95 when notches were added. You cannot just cut slots. I plan to try to clearance the 3400 lower intake and leave everything else be, since the engine runs great as is right now. No point fixing what ain't broke. above all... read the other 3400 intake swap thread. and I plan to up the exhaust to 3.4 duals soon too.

GP1138 Posted February 4, 2007 Report Share Posted February 4, 2007 If you have a '94, you need newer heads. I believe all 3400 manifolds are the same size, even from the vans, which started getting 3400's in '96- look for them in newer Lumina vans, I believe, at least that's what I was told.

Dirty Rockstar Posted February 4, 2007 Author Report Share Posted February 4, 2007 I want newer heads, but Im not quite sure what all is involved with what Ken says.. Where can I get that done? I'll find all that I need in the vans.. I like the blank Plenum actually.. Would allow me to have it custom engraved if I were to turbo (HAH!) or some such shit.. ..If I get my Vert and it's a PushRod, Ill do that then..

digitaloutsider Posted February 4, 2007 Report Share Posted February 4, 2007 U-van's started getting the 3400's in 1996 across the board: Trans Sport, Silhouette, Lumina APV. Quote Link to comment Share on other sites More sharing options...
97loudcut Posted February 4, 2007 Report Share Posted February 4, 2007 I'll be looking to do this as well pretty soon. I know I want John and Ken there when I do it. I have a 97 3100 though so it's direct swap for me. Quote Link to comment Share on other sites More sharing options...
