3.9 to 5.9 magnum swap in my 2000 Dodge Dakota

Here, because this an airport run way, would be too short for high powered cars, a little municipal air port. There are a few 1/4 mile tracks in our province.

Ah that explains it - thx.

Well no track time this fall. The truck was cruising fine, going to get a new washer from the city. Then all of a sudden, the temp gauge starting climbing. Top up and over heat twice more. No coolant the oil, a head must have cracked leaking exhaust into the rad. Looks like two new Magnum EQ heads will be going this motor.

Tried a fail safe thermostat, it locked in the open position, still overheated. Tried no thermostat, still overheated. I plan on driving it just around town this winter. I figure on around $2000 Canadian with shipping and exchange for, gaskets, aluminum intake pan, heads with Hughes springs with quality valves and bronze guide liners that won't have the valves stick. I will also do 1.7 to 1 non adjustable Harland Sharp rocker arms to take advantage of the much better flow of the EQ heads.

Bummer...and congrats.

EQ heads and gaskets ordered. I bought the .028" head gaskets which put it around 9.6 to 1 with better quench. Time to pull it back apart again this weekend.

I received the gaskets, thick aluminum plenum plate and Ram EQ heads. Nice much thicker castings that flow 233/188.

Running and no more puking coolant or going in the oil.

Well after the truck just running shitty after the head swap, I found 2 issues. First it was running on 7 cylinders, number 8 had a wire off on the injector. Noticable miss, I guees so. Second is the reason the truck has run shitty on and off. I "upgraded" to a brass BWD cap, some upgrade. It never sat on the motor properly, wouldn't tighten down, pretty sure it was moving, causing shitty running. It got really bad barely running, I had a Champion cap, brand new. I found the rotor with the spring broken off. This cap tightened down all the way and replaced the rotor. No more bad missing or violent shaking in reverse. Finally!

Hell yeah! Glad to hear you got that sorted out. I know how frustrating it is to have a vehicle give you trouble over and over. My truck has been doing that lately. I still have a coolant leak to find.
