oakland240 Posted July 10, 2011 Share Posted July 10, 2011 I am thinking about ordering the same headers, I have a '71 240z, does anyone know if the clearances should be the same? Or has anyone installed the 33ap headers on a 240? very helpful before I spend the $400. Thanks! Just as an update I bought the C33 headers for my '71 240z...they are NOT bolt up in my case, luckily I am local to Sanderson and they have been EXTREMELY helpful with modifying them to make them fit, if anyone would like pictures of some of the clearance issues and modifications I can upload them before they get installed on Tues or Weds. Also for anyone in my situation, make sure your oil pan does not have flares on the side as the passenger side headers WILL NOT FIT. I also had to have the headers dented to clear the steering shaft (not sure the correct name) and the passenger side frame rails and also the suspension thingy the sits below the frame rail (yeah I'm pretty clueless about suspension). I also had to shave down the bellhousing on my T5 where the slave cylinder goes, but that was fine since I am using a hydraulic throwout bearing. In addition I bought a oil filter relocation kit that looks pretty nifty from Trans-Dapt. I have a pretty hot engine which will benefit from the log tubes, but I encourage anyone with a similarly limited knowledge of car things to avoid the long tube headers unless your engine really requires them. If anyone wants pictures or elaboration I can try to help you out. PS shameless plug, Jeremy at Sanderson Headers has been really helpful, I have been there a number of times and he has not charged me extra to get all the modifications done and he even gave me a discount for be local/jobless/paying cash/etc, if you are buying headers for a Z I would ask for him.

luigi Posted July 11, 2011 Share Posted July 11, 2011 Please, Please take pictures. thanks for offering. I bought a set of those (c-33-ap) and while they would bolt up they were all over everything. thanks Lewis Quote Link to comment Share on other sites More sharing options...
oakland240 Posted July 12, 2011 Share Posted July 12, 2011 Drivers side (tape showing where additional clearance needed for steering shaft) Good thing I didn't need that slave cylinder huh? Passenger side (tape showing where runs into frame rails) Showing suspension part interference, you can see the above photo how this has already been clearanced. Tomorrow I will be taking them back to Sanderson to have the taped areas worked on. If you need them worked I would either call them and ask for the best advice on how to do yourself or maybe they could measure mine and duplicate the clearances for you?

GrtRat1 Posted July 16, 2011 Share Posted July 16, 2011 First time poster here.. I use to have a 70 240Z with a 383 stroker (Early 90's).. The headers I had were made by hooker..The driver side didnt fit.. So I mounted the header upside down on the pass side.. Used a torch to heat up the tubes at the head and had to bend them outwards alittle.. I cant wait to get another Z to build and have fun with..

lazycat5 Posted July 22, 2011 Share Posted July 22, 2011 I got a set of the (c 33)'s this spring and the mods made by oakland240 are the same as what i did. I however use streght plug heads and needed to dimple there to. i didn't like the collectors so i cut them out and used a set of merge collectors from edelbrock that look great. The hardest part of the install was bending the pasenger side header to clear the frame rail. Overall i am very happy with them. Not a bolt on but close enough for anyone to install.

Smyrna388Z Posted September 6, 2016 Share Posted September 6, 2016 Sanderson long tube c33-ap are now installed on my 1976 280z with a Chevy in the JTR position. Minor clearancing at the frame rail on the passenger side, but this could be eliminated with manufacturing differences between the headers. My steering shaft has been relocated, but suspect the stock location would be very close to working. Ground clearance has not been an issue. Works great when you want a 1-3/4 long tube header.
