They fit perfectly in my 72 Z only when I used JTR motor mounts. They are long tube headers and were easy to install. S&S is located in Arizona. Good luck.

Heavy Z Posted February 5, 2004 Share Posted February 5, 2004 Wow, Hanns just laid down an excellent recommendation!!! I'm running 1 5/8" Hooker blockhuggers w/ 327 in jtr configuration, with a 400 I'd jump on the bigger long-tubes. Quote Link to comment Share on other sites More sharing options...
Guest steveo Posted February 5, 2004 Share Posted February 5, 2004 any clearance issues with the long headers? Quote Link to comment Share on other sites More sharing options...
Tim240z Posted February 5, 2004 Share Posted February 5, 2004 any clearance issues with the long headers? They hang a bit low on the passenger side....some ground clearance issues are possible depending on whether or not your car is lowered.

Turbo Meister Posted February 5, 2004 Share Posted February 5, 2004 any clearance issues with the long headers? Steveo, As Tim240z indicated, the S&S headers are lower on the passenger side. If you check in the "exhaust" forum, ZRossa posted a similar question on 12-30-03 titled "SBC full length headers". There were several responses and even pics of these headers. This post can be found on the first page of the "exhaust" forum. I never scraped my headers either street driving or drag racing. However, my Z never saw any offroad or unfriendly asphalt action.

deMideon Posted February 5, 2004 Share Posted February 5, 2004 Also depends on which trans you use... I am using the T-56 so I have to go with a different bellhousing, since with the stock one, the slave cylinder will stick out in the way of the collector. Of course there are many other reason I am using the weir bellhousing! I would also suggest getting a new crank and having it internally balanced so you will have a wider selection of flywheels!
