I purchased a 71 240z with an L28 block and an N42 head with a Clifford intake. I am switching back to S.U. carbs and am looking at a pair of 3 screw carbs that are available but no manifold. Can someone pls. tell me what manifold I will need to make this come together.

Any 240Z manifold will work. Contact ZTherapy as I'm sure they have a few on-hand.

Thanks Gary. I was concerned about the hot water passages that I heard the 3 screw carbs have.

Which carbs are you going to be running? 3 screws have the provisions for water through the insulators into the carb bodies.

How much cold weather driving do you plan on doing.

I was hoping you would chime in Bruce. Probably none to very little. I live on Vancouver Island, very mild and the car will be a fair weather driver only. I am looking at a set of 3 screw carbs with the float bowl drain plug. The seller is trying to find the manifolds for them.

Well, frankly any manifold will work 3 screw, 4 screw, or flat top, matters not. Flat top balance tubes are uglier than home made sin but other than that I believe the flat top manifold manifold might even flow a little better than the earlier manifolds. That is based ONLY on looking into the intake runners on both manifolds.

We are also seeing more guys wanting to disable the water thru the manifolds entirely. Just one less thing to go TU and leave one standing beside the road......

Do you know Greg McCauley on the island? He has Some Z stuff. I know he has a primo early air cleaner he'd like to sell.....

Thank you for the info.. I had visions of nightmarish parts hunting. I have owned Zs in the far, far past but then they were new and did not require a whole lot of tinkering. No, I am not acquainted with Mr. McCauley. It would be nice to be in touch with someone locally with Z interests. They are as rare as hens teeth here. ( That is rather spooky. The previous owner of the TR6 I own, was Joanna MaCauley. The TR6 had a totally B.C. history.) MMMmmm

Email me at ztherapy@msn.com and I'll hook you up with Greg. There's a club on the island too. VIDE Vancouver Island Datsun Enthusiasts. Stick with us, we'll get you up to speed.....

If Bruce and or Greg can not help you, PM me.

Hi Dan. Nice to hear from an Albertan. I lived in Calgary for 17 yrs. The guys have me on the right track. Thanks for the post. Larry
