Re: Anyone familiar with air cleaner setups?

Everything looked mint when I had the head off, no signs of damage at all in the cylinders. And I doesn't burn hardly any between changes. Maybe "constantly seeping oil on top the the valve cover' would be more accurate description, ha-ha. I have seen a six with bad rings, and THAT engine was f...

Anyone familiar with air cleaner setups?

Hey guys, Yesterday at the scrap yard I opened the hood on a '70 f100 to find that it is totally complete, no one has touched the 240 or anything else. My '73 air cleaner has a hole in the pan that is patched, so I took the assembly off of the '70 truck. The '70 had one hose running from the REAR of...

Re: Quick jetting question Carter YF

So here is an interesting development. I took out the factory jet and metering rod and measured them against the reproduction carb versions. To the best of my ability I measured both. The ford main jet was just about .104-.105", and the metering rod seemed to be .080. The reproduction jet was a...

Re: Quick jetting question Carter YF

Well. Switching to the .104 metering rod and jet rendered the truck just about undriveable. Too much bucking and sputtering to really get underway. So I guess I am going to put things back the way they were for now. I guess I need a better way to get the jetting set up correctly on this thing. -Jesse

Hello,

Just did a quick measurement and the front manifold sits about 8 -1/2 inches away from the block. On my 73 f100 this would put it pretty close to the inner fender well if used on the rear 3 cylinders, but it might sneak by. Otherwise I don't see why It wouldn't bolt in place (?)
