Thread: SB Ford Roller Rockers - 1.7 ratio, Pedestal Mount

Tweet

Description from the Summit cat:
"These pedestal mount Energizer rocker arms from Crane feature an aerospace vacuum die-formed aluminum main body that offers extreme strength and light weight. Their needle-bearing fulcrum and roller tip reduce friction, lower engine oil temperature, improve response, and increase horsepower and rpm. These rockers are great for street and moderate race use."

These are the 1.7 ratio Crane/Ford Racing full roller rockers 44746-16 / F3ZE-6529-AB
This set has - maybe - 1500 miles and look like new. They are individually oiled and wrapped. The set comes with the channels and a new set of unused shims.

These were $240 . Now $175 INCLUDING shipping

Wrong place wrong time.My bad

Gary,
Is a guy's "Parts For Sale" post really the place to engage in a discussion about the pro's & con's of aftermarket rockers for performance? The way I see it Dave is offering a smoking deal, over 30% off when you consider shipping, for a set of barely used Crane rockers that he chose to change out on his engine, but that might be exactly what another guy has been looking for. Maybe if you want to debate the advantages/disadvantages of particular parts it would be better to start a new thread instead of muddying up a guy's "For Sale" thread? Just sayin'......

Sorry to butt in Dave, but you'd probably not have said anything, nice guy that you are.

Roger - thanks for 'chiming in" but I'll answer it anyhow even though Gary did his edit

Gary - for a grocery getter engine, you probably wont see much of a difference. Add a little more camshaft, you will see some help. Roller rockers are just that. The aluminum after market versions will add rollers at the trunnion as well as the valve tip end instead of friction/sliding action in those places. Also, they supposedly run cooler. Now, the big advantage to this particular set is that instead of being the standard Ford 1.6 which translates to my particular camshafts lift as .498, the 1.7 roller rockers - those valves will now open to about .530 lift - an inexpensive performance adder. Supposedly it will work to improve the actual camshaft overlap - but I really kinda doubt that. As far as my car, reverting back to 1.6 ADJUSTABLE rockers has taken the edge off the idle speed(better), the exhaust note(worse) as will as the seat of the pant feel(not as good). BUT they are a PITA to adjust preload on, at least my engine as I would have needed longer, custom built push rods. See my long winded thread for that story.

Most other folks, according to another Ford related website, 'love' these rockers
