ZT Carbs and Advice

[texasz]

Anyone have any good advice on what carbs (or carb work) I should put on an F54 block/N42 head engine? I'm planning on ordering them from ZT and just want to know what I should be asking Steve for. I see the regular reman carbs on the site for $595, I was also looking at the Outlaw setup but they said that they really do not do this any longer and are not so sure that it was ever really any better.

I also plan on sending in my N36 intakes and having them worked over removing all the un-necessary garbage (smog crap, etc) from them and the balance tube.

Any information would really be appreciated!! :classic:

Hey Allan,

I got a set of zt carbs back when Scott Bruning was running the show. They're really good stuff. The shafts are machined where the butterflies attach for a little more flow. The have the roller bearings on the shaft ends. From a "seat of the pants" opinion I really like the way the zt carbs seem to "come on" around 3000 rpm versus stock. I dont know if this is due to the aftermarket engine cam plus the zt carbs, but the stock carbs didnt have that "surge". My 73 uses the stock intakes but I too have some N36's I am getting ready to install if I ever get the time. I'm going to port match them and do a little parting line sanding. I drilled and tapped the smog ports and vacumm hose fittings and am plugging them off. I wish I knew a shop that did extrude honing and didnt charge an arm and left nut because I here that's a good way to better the flow. The balance tube from the 240Z is supposed to work on the N36 setup but I havent checked that out yet.

Anyway, the carbs are superb!!

Much luck,

Chris
