well a bone stock one that was tuned for milage to begin with. Every body says you can't get milage out of these engines but you can if you sacrafice some power and I did. That's not the case now, I'm working with a alterative fuel engineer to get better milage. :thumbup
I will as soon as i can. I'm under contract right now and can't say to much info yet but let's just say it will be amazing. HE's getting around 50 MPG on his 81' suburban right now. We are trying to put together some plans so the average day wrench turner can do this. We almost got it down hopefully by the end of the year it will be ready to spread out. People can think I'm totally crazy but hey oh well I just might be.
The only problem is without spending 40-50 thousand is engine life will be in the 5-10 year range depending on how much you drive. Oh yeah I'm shooting for 50 MPG with my 460. That's all I can say for now. A soon as I can I'll give updates.
i have a 460, 36s and 4.10s and i get 8 mpg... so when you get this hush hush thing done, i would be innterested. who cares about engine life, with the money saved i will just buy new to me used 460s... id be happy to see something in the double digits. AXE
Almost the same thing I was working on. The guy decided to screw me so :enforce him. This is easier for the do it your selfer to put together. I should have one with in a few weeks. I will post results as soon as I can.
