Cheap 4.0 head
If anyone has a 4.0l head that has been sitting out in the rain, covered in sludge, warped, cracked or just in general unusable I am interested in it. I'm willing to pay 20 bucks for it. I am in 06066 and I'll drive to pick it up.

To keep my boat in one spot while I fish!
I need it for a fitment job for an exhaust. |

Hopefully someone will have one out close to me. I'll try the scrap yards tomorrow.

Being familiar with your past work, Now you putting together a turbo system? Or is it a surprise? :)
|
Not to much of a surprise. The turbo was always the end goal. I wanted to do a supercharger though. Hopefully I'll find a deal close to home.

Can you elaborate a bit more on that?

Let me see if I can round up a picture of it for you. But the design is simply short stubs out of each port which run into the side of a larger straight tube, lets say 3 inch in this application and then to the turbo. But what is important is how the stubs are aimed into the side of the larger tube which creates a scavenging effect from the ports and a swirling effect towards the turbo. And the section of 3" can be easily press bent to the perfect location for where you want your turbo and outlet to run.
I finally ran across one you can buy for these Jeeps that is designed the same way. These short stubs aimed correctly into the side of a much larger tube is how they were designed on the early aircraft that had turbos. In fact... With how these are designed, I would bet that they would be just as or more efficient than headers but in a simpler smaller package even on a non-turbo system. I will try to find a picture for you... But it might be tomorrow. :) |

I appreciate the offer Ralph. I'll look around for something that is pure junk as what I'm going to do could turn a good head into junk. I'll let you know.

I'm still trying to find a picture while multitasking. I had one in my files somewhere but recently changed operating systems from Windows to Linux and things are not where they used to be and I have to dig deeper for it. I'll keep digging or go searching on the net to find it again. I knew right where it was before I changed this thing over.

You mean like a non equal length log type manifold?

For the life of me I cannot find that picture. I know I saved it because it was such a simple and common sense design. And the one I grabbed was actually fabricated for these 4.0 engines and put the turbo in the best spot. Let me try out my new drawing program in this new linux software and I will try a crude drawing. I know once you visualize it you will understand the concept completely and adapt it from there to fit what you need. But the larger tube log was the important difference because this created a situation where different length stubs didn't matter or affect the overall evacuation. |
