Why "BOSS" 3.0?
Well, I figure that since the 3.0L "Vulcan" engine (built at the Ford Lima Engine Plant) shares the same pedestal mounted stamped steel rocker as the BOSS 302, BOSS 351 and other famous Ford Engines, it deserved to follow the proud heritage! (Besides, "SHOlcan" or "VulSHO" just don't do it).
Note: This info is posted for public knowledge as a means to get 3.0L Vulcan Owners/Modifiers heads out of the sand. It is not for reuse or reposting and in no way a means to recruit or solicit funds in anyway. No parts or items are sold as "BOSS 3.0".
This is going to be a hybrid of 3.0 SHO® and Vulcan® V-6 bottom-end parts and BOSS 302/351 valvetrain parts.
"The hell you say!" Look it up, it's a scary fact that has laid dormant since 1986. I have already cracked the valvetrain secret and have started work on the bottom-end!
Are you ready for Mild/Stock roller cam shaft and STOCK push rods actuating stud mounted (or bolted), adjustable (or pedestal mount), 1.72:1 needle bearing roller rocker arms? What if they were pushing titanium retainers, E351 springs and 1.7"/1.5" valves?
How about a (conservative!) 6,667 RPM engine (3,500fpm piston speed) that works with all factory emissions equipment, is undetectable during a visual inspection, PASSES A SNIFFER TEST, and puts more power to the ground than a 4.0L SOHC?
Stay tuned, because it is about to become a reality! I will post the results of each step!
Phase 1: The drawing board
Currently this is pure theory (sound, but still theory). Do not jump into this, or any other
technical project, until you have checked the numbers, math and specs for yourself. I will update this page as I get
BOSS 3.0 Valvetrain:
-Roller Cam Upgrade (for pre '94). Keep your stock block, get Fords 3.0L lifter guides and retainer (no swaps available). Get the lifters from PAW ($89.95 for 12 versus $16.95 ea from Ford), drill and tap the block for attaching bolts. Done! (I am getting a pre-'92 block later this month to verify this info. standby!)
CamCraft makes cams for the 3.0L. If you need a roller cam, you have to mail yours in. For a roller cam upgrade, you will need a roller cam core to get the full benifits.
1.73/1.75/1.8:1 Roller Rockers, larger valves, 3-angle valve job, SVO351 Sportsman Springs w/105 lbs seated pressure, nylon valve stem seals, larger stainless steel valves (1.775" Intake, 1.5" Exhaust?). Ported and Polished heads.
200+ HP, 360CFM and 6,500+ RPM? I think it's right here!
