So, the power steering pump that comes with these engines is too low flow to support hydro-boost and steering. But it has a 3 1/2" pulley. To make matters worse, it is a 5/8 keyed shaft. After days of research, I realised there are no pumps that flow enough, and have the keyed shaft. So... I got...
I noticed that it seemed slower. But, according to the speedometer, we gained a few mph in the 1/4 mile, and gained alot of driveability.
Also, egt is lower. The up-pipes don't glow red anymore!

No height issues mike. It isn't that tall. It is long. Gotta slide the trans back about 2 inches... so I can use my dodge fan.
clears front axle nicely. Power steering pump was hitting my steering gearbox. Figger if I'm doin this, may as well do it rite!
