We Test It
Break-in Oil

We were breaking in the engine on the CC/Rambler when we noticed a big list of do's and don'ts pertaining specifically to the new MSD distributor gear. It should be lubed with a zinc- or moly-based break-in lubricant (like the tube of goo from Comp Cams) prior to the installation of the distributor. No synthetic oils should be used during the break-in period. Use only standard 30- or 40-weight or multiviscosity oil such as 10W-30 or 20W-50. On highly modified engines with more than 70 psi (cold), the gear should be broken in with a racing-grade mineral oil. These warnings led us to use engine break-in oil and we haven't had a problem since. The oil has extra zinc and phosphorous that is designed to take it easy on new parts in a racing engine, and it will even make sure your cheapo flat-tappet cam stays oval shaped.
How Much: $7.95 per quart

A Watt's Link for Everyone
What It Is: Fays2 Watt's linkage
Why You Care: A Watt's linkage is one of the best ways to control your rear axle's movement. We discovered Fays2 while researching last month's S197 Mustang article. We were going to put it in the article but ran out of space. We have the space here, though. Good thing, too, because Fays2 makes these Watt's link kits for a ton of other applications, not just new Mustangs. You can buy a kit for first- through fourth-gen Camaros and Firebirds, '65 to '73 Mustangs and Cougars, Fox body and SN-95 Mustangs, and GM A- and G-bodies. This is a bolt-in kit. The Watt's frame attaches to your car's chassis, and the links attach to clamps on to the axletubes.
How Much: The S197 Mustang kit costs $650. Other kits are similar.
We Say: Unlike Panhard bars, Watt's linkages don't allow any lateral movement of the rear axle.

Horsepower Gains That Sounds Great
What It Is: Millerspeed's new budget-friendly beltdrive pulley kit for small-block Chevys
Why You Care: Millerspeed's new beltdrive kit replaces your stock V-belt pulleys with 2-inch-wide cog pulleys that eliminate belt slippage, increase horsepower, and have a wicked blower belt whine. The kit is designed to work with stock long water pump brackets and your stock power steering pump and pulley. The pulleys are precision CNC-machined in the USA using aircraft grade 6061-T6 billet aluminum and come brilliantly polished. The kit includes a heavy-duty HTD blower belt. Millerspeed also offers a variety of other kits for both big- and small-block Chevy and Ford applications, with kits available in 1- or 2-inch belt widths for use with or without power steering and A/C.
How Much: $339.95
We Say: We dyno-tested this system in the Dec. '09 issue and gained 10 hp at 5,500 rpm by simply changing over from stock V-belt pulleys.

It Does Everything
What It Is: Pioneer's new AVIC-Z120BT
Why You Care: We normally aren't into high-end car stereo stuff, but sometimes a product comes along we find intriguing. This is Pioneer's new flagship AVIC-Z120BT Navigation and Entertainment System. We think they need to come up with a simpler name. Still, if you're into high-tech electronics, this thing is cutting edge. It features a new touch/slide interface like an iPhone that is much more intuitive to use than other systems we've seen. It offers an iPod connection, Pandora Internet Radio, a Bluetooth connection to your phone, 3-D navigation, satellite, and HD radio.
How Much: $1,799. Yeah, that's big money, but this is probably the most advanced car stereo available today.
We Say: We're not doing it justice here-you have to see it work in person.
