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.
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.
