PS. I once had a 318 in a 69 sport satellite that had a rod Knock that
sounded like rapid fire lead pipes banging. I drove it a long time but
couldn't kill the engine. I finally burnt the 904 tranny by keeping the
Idle cranked at about 1200-1500 to keep it running at idle. When I drove
it to the junkyard in first (the only gear left) I asked the guy if he
cared if it was running or not, he said no it will be crushed and he told
me were to park it.
Well I had always wanted to see rods go through the hood in a blown engine
and I thought here is my chance. I put the car in park and stomped on the
gas and screamed that engine until the valves were floating. That bad rod
was banging away like rapid-fire cannon shots now, but it still wouldn't
blow. For 5 to 10 Minutes I laved on this engine full throttle in park and
it would not blow. I finally shut it down handed the guy the keys and
walked away defeated.
Now that is an Engine!

The 2.5 liter engine was the last gasp of the slant six era of engine
design. With its long stroke, single fuel injector, and low performance -
high durability design, the 2.5 provided better low end power and more
torque than most competitive engines. It was also larger than most engines
with similar power outputs.
A 2.2 liter engine with a longer stroke and balance shafts, the 2.5 was
only available with fuel injection. It was smoother and quieter than the
2.2, and had more power at the bottom end. However, with its long stroke
and balance shafts, it was not well suited to high performance
applications. The 2.5 turbo engine was not supported for long.
The design of the 2.5 may have been influenced by the Mitsubishi 2.6,
which also used balance shafts.
Dan Stern reported that the Slant Six and 2.2/2.5 liter engines were both
products of the engineering genius of (amongst other people) Willem L.
Weertman. He was Managing Engineer--engine design from '55-'62, Assistant
Chief Engineer--Engine Design and Development from '62-'76, and Chief
Engineer--Engine Engineering from '76-'87. This means he also had a large
role in just about everything we love, from the Slant 6 through the LA
engines on up through the Hemi. They pulled him out of retirement for the
V-10 projects.
