Just ordered a Lee 670 12.7:1 Power Steering Box

[Buffalobillpatrick]

I have read so many posts giving them high praise, I just had to get one.

Starts with a BRAND NEW box:
Full disassembled
Hand mic every ball and replace as needed
Re-valve box with R&P valving
Zinc plate case
Blueprinted internals to racing tolerances
Dyno tested on bench

From Marcus at SC&C
"the 670 box it is worth it. You save about 6.5lbs. which is nice and it`s a bit smaller which is nice too but the big difference is the valving. When they say they have "rack and pinion valving" it`s not marketing double talk for tuning them to feel more like a rack and pinion it means that the actual hard parts of the valving are made in the same manner,using a one piece spool valve and stub shaft that gets rid of the play in the older 800 series 2 piece/floating system. The sizing of the valve gear is also different. This is a big part of what makes racks feel more responsive and precise than older boxes and the 670 box has it too"



I'm sending my Power Steering pump out to Lee for rebuild to match & be dynoed with my 670 box.
