89GPSE Posted January 26, 2005 Report Share Posted January 26, 2005 http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7949887279&category=33617&sspagename=WDVW Will these work with my 3.1 intake and plenum? I think they will but thought I should ask you guys just in case. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted January 26, 2005 Report Share Posted January 26, 2005 No, to use those heads, your need a 3x00 lower intake and upper plenum Quote Link to comment Share on other sites More sharing options...
rudefyet Posted January 26, 2005 Report Share Posted January 26, 2005 wut he said I found some intakes on ebay too look here (FYI 3400 and 00+ 3100 intakes and heads are the same) http://www.w-body.com/forum/viewtopic.php?t=25183 Quote Link to comment Share on other sites More sharing options...
Carotop Posted January 26, 2005 Report Share Posted January 26, 2005 I'm gonna hijack this forum for a second. Would a 3400 head swap be worth it? And if so all I need is heads intake manifolds and thats it?? Quote Link to comment Share on other sites More sharing options...
ikessky Posted January 26, 2005 Report Share Posted January 26, 2005 Yes it's worth it. The new heads and intakes breathe better and you get factory roller rockers. I believe all you will need are the heads and upper/lower intakes. You might have to do a couple slight mods for the temp sensor and EGR though.

rudefyet Posted January 26, 2005 Report Share Posted January 26, 2005 60v6 had a nice little write-up on the 3400 head/intake swap Quote Link to comment Share on other sites More sharing options...
Carotop Posted January 26, 2005 Report Share Posted January 26, 2005 Yea I'm gonna check that write up out right now. And should I just get em ported since they'll be off the engine anyway. Quote Link to comment Share on other sites More sharing options...

Carotop Posted January 27, 2005 Report Share Posted January 27, 2005 Well what all do I need??? Quote Link to comment Share on other sites More sharing options...
Bossman429 Posted January 27, 2005 Report Share Posted January 27, 2005 look at the write up on 60*. I think you also need a p/s pump + bracket, Alternator, front timing cover, etc, having not done it myself, I'm not totally sure. read this: http://www.60degreev6.com/modules.php?op=modload&name=Pushrod&file=index&req=viewarticle&artid=35&page=1[/url] Quote Link to comment Share on other sites More sharing options...
Carotop Posted January 27, 2005 Report Share Posted January 27, 2005 Well I might be doin a full 3400 swap in an 89 Cutlass I might get soon. So if anyone wants a 93 Cutlass with 107k on it talk to me. Quote Link to comment Share on other sites More sharing options...
