Danno74Z Posted January 19, 2004 Share Posted January 19, 2004 A question for our LT1 engine folks or anybody who may have experience in the header department? I went through the search engine and I came up empty on this one. As you guys know when you install sporty headers on the LT1 engine they hit the knock sensor. Not a big deal, but I thought perhaps if I could use mid-length headers (pictured below) I could skirt the relocation of the knock sensor entirely. I know its a long shot but has anyone tried this type of header within the confines of the Z engine compartment? Thanks for any help, Danno74Z Quote Link to comment Share on other sites More sharing options...
Tim240z Posted January 19, 2004 Share Posted January 19, 2004 At first glance it looks like it will be too wide and hit the frame rail where it meets the firewall at the bottom. Tim Quote Link to comment Share on other sites More sharing options...
Danno74Z Posted January 19, 2004 Author Share Posted January 19, 2004 That was my thought also but if someone has actually tried it I could forget about it and move on. I know it's not talked about in the JTR book and most folk’s just use the block huggers as recommended but I do like to experiment some. It would be an expensive mistake if they did not fit as I don't think anybody would take them back. Danno74Z Quote Link to comment Share on other sites More sharing options...
Tim240z Posted January 19, 2004 Share Posted January 19, 2004 Danno...the exhaust HAS to be tucked up directly under the starter. From what I can tell from that little picture, it actually runs under and a bit next to the starter....a big no go from my viewpoint!

Dan Juday Posted January 19, 2004 Share Posted January 19, 2004 I think you would be looking at the same issues as any SBC in the JTR position. Clear the steering shaft, clear the frame rails, clear the T/C rod mounts. The knock sensor is really not a deal since it can be mounted anywhere on the motor or bellhousing. In the two EFI swaps I've done I relocated it to the same spot, a boss on the side of the block near the oil filter. The threads are straight and not NPT but it's an easy retap. The other plus is that it's near enough to the original location that the wire reachs without cutting. Quote Link to comment Share on other sites More sharing options...
mas28O Posted January 19, 2004 Share Posted January 19, 2004 You can use the S&S headers for the LT1 they are 13/4 full length. They hand down low but they fit. I have a set here if you need a pick. Mike Quote Link to comment Share on other sites More sharing options...
Danno74Z Posted January 19, 2004 Author Share Posted January 19, 2004 You have convinced me to move on - Thanks Danno74Z Quote Link to comment Share on other sites More sharing options...
Danno74Z Posted January 19, 2004 Author Share Posted January 19, 2004 MIke, I just saw you post and I figure the full length headers are such a hassle to deal with in the Z that I don't want to even go there. Thank you for the offer for the picture but it's not needed. I'm sure some HP is left on the table with using block huggers over full length but it seems to be next to impossible to find ones that work in the Z very well.

mas28O Posted January 19, 2004 Share Posted January 19, 2004 I was using block huggers when my LT1 z was running 11's. You should be ok with them. Quote Link to comment Share on other sites More sharing options...
