I have a stock 2005 5.7 in my Duster. 833od, 2.76 gears. I consistently get 22-23 mpg in town and 27-28 on the highway. That’s with mashing the accelerator occasionally.
I have a '73 Duster with an 833OD, 2.76 gears and 26" tires. I recently swapped a 5.7 hemi into it and it goes like a bat outta hell. At 80 mph it's taching about 2100 rpm. Has gobs of low end torque. I'm going to swap to 3.23 gears when I put a sure-grip in it.
Here’s what my exhaust manifolds look like. I had a leak on the driver’s side because I hadn’t got a flange on quite flat. So I buzzed in a little 6011 and milled it flat.
A trashed connecting rod makes a nice collar for bolting the exhaust to the manifold.
I didn’t take any pictures of my manifolds before I installed them. These are the best I could get. I will get better pictures at some point. The alternator pulley is something I made from scratch. It’s easy if you have access to a lathe! I have to add that I’m a butcher class machinist!
I had a lot more time than money so I did a lot of things myself instead of buying them. I converted the throttle body to cable operation.
I made my own coil driver box.
I converted the old school alternator to work with the serpentine belt.
I made my own power distribution box.
I made a...
It’s alive! Went for a couple of test drives. I can’t say enough good things about Megasquirt and the auto tune function. Still have a ton of things to do before I can really drive it.
This thing has been laughing at me for months but I have made some progress. It’s difficult to go out to a cold garage and roll around on the floor. Just have to keep on it.
I used a 5K potentiometer and attached it to the middle gear. Thinking about using the original actuator for cruise control in the future. I’ll see if I have a picture from my testing.
I’m in the middle of the swap so it’s not connected. I test ran it on a stand. I drilled and tapped the shaft and added the external TPS potentiometer.
Out of my '73 Duster. Not the original engine, think it's a 225 but not sure. Includes bell housing, clutch, starter, etc. Located in Berthoud CO. Pick up only. Everything for $100.
It was tough because I left the transmission in place so I could locate the engine. I’m making my engine mounts because I’m too cheap to spend $300 on something I can make myself plus I’m using the slant k-member, so the TTI mounts probably would need tweaking.
