Small block. I bought a Mopar performance 5.9 magnum short block, still sealed in it's crate from 1999. I'm a welder by trade, and haven't built an engine since 1997, but I would assume that it'd be a good idea to at least go thru it, and verify torque specs.The engine came with closed chambered...
I was thinking the same thing with the intake. My friend would like to have it for his stock fuel injected magnum powered rock crawler. I could buy a dual plane to better fit my needs.
The dart currently has a 4 barrel stock 318 in it. I will obviously need a different flexplate and other ****. I was only looking for around 400hp cruiser motor/daily driver. This should meet most of my expectations when done. All of the additional upgrades will be suspension and drivetrain.
I agree 100% My dart has a freshly rebuilt 904 with a shift kit that probably won't last long under the new power, plus the 8 3/4 is one legged, and still has the slant 6 leaf springs.
That's what my intuition is telling me. But I'm sticking with the heads I have for now. Aluminum heads will be the next upgrade. I'm just looking to smoke my friend's 347 stroker in his '65 mustang
It has never left the crate. The short block is solid & brand new. I'm just worried if the heads are good to just bolt on with stock parts. Not sure what is needed, online searches have all led to dead ends, with no real answers.
