Where does this project stand? It's getting on to a year later.
The engine runs great and is getting stronger each time I drive it. I had a few minor leaks in the plenum that I had to find and fix, but no big deal.
Still getting the 'break in' mileage on it. But my sense is that it is running lean, so I'm not taking it out for long drives until I get the tuning done. So it's kinda of a catch 22. LOL
I will say this though, I already did a 7.1 sec 0-60 with no tune and not broken in. That's 1.3 seconds faster than stock. I think low 6 second times is no problem.
The bottom end is very strong. Punch it at 30mph and it puts your head right into the headrest.
The top end seems to not pull as hard as it should. Don't get me wrong, it pulls good, but I know there's more there that will come with tuning.
Also as I drive it, I've noticed the exhaust note gets deeper and deeper which is a bonus.
So, I'm working on a couple of performance mods which I will be offering. 1 is a port sharing kit. The OEM intake ports are too small for the 3.5L engine, so I've got a simple kit that will be a direct bolt on to fix that. 2 I'm building a direct bolt on kit to install the 74mm throttle body.
Currently I am building a 4.0L for my magnum 2.7 swap. This engine will have allot of head work done to it. My goal is to get as close to the 100hp per L as I can.
With the 3.5 I specifically wanted to build the engine with "off the shelf" parts. The 4.0 will be much more custom.
I also just started a FB group and I hope to get more performance minded 3.2, 3.5 and 4.0 people involved there. Log into Facebook | Facebook
so that we can start building the parts that have been ignored for too long. If the link doesn't work just a Facebook search for "Mopar 3.5".
Here's where it is right now.
