Guest super280z Posted July 20, 2001 Share Posted July 20, 2001 howdy All, just a quickie for any of the guy's that have completed a 94+ lt1 swap on a 280. are there clearance problems with block huger headers in this configuration? i know that it really depends on the positioning of the mounts but i've read about having to "relocate" the flange after welding 2" or so of pipe on. are there any other brands or styles that clear? any info would be greatly appreciated. its great to finally post with a group that loves joining great engines with super cool cars just cause we can. 81 280zx Quote Link to comment Share on other sites More sharing options...
DavyZ Posted July 21, 2001 Share Posted July 21, 2001 Welcome to the forum! Keep asking questions and someday, you'll have the answer... I hate to see a post go unanswered, but you narrowed down your question to those guys that have done the '94 and later LT1 swap. I have not, but I don't see how there could be interference using the block huggers--are you referring to interference of the flange with the block or with the frame? A good company to chat with would be Sanderson--pricey, but good quality. Anyone else? Davy Quote Link to comment Share on other sites More sharing options...

Guest 72240Z Posted August 30, 2001 Share Posted August 30, 2001 The reason you have to move the lower flange down two inches is to clear the knock sensor that is screwed into the side of the block. Quote Link to comment Share on other sites More sharing options...
