    Please excuse me my fellow HAMB'ers, I know the big Boss is on the fringes of what a "traditinal" hot rod engine is, BUT! for those that are neck breaking power lovers this thread is for you. Now the lowly big block Ford has never had much of a following outside of 4 x 4's and Ford loyalists, due largely to misinformation and preconceived notions. To some who have tried them these cheap torque monsters= low $ to hp ratios. Of course I'm speaking of the bread and butter 429- 460 canted valve varietys. Some of the goods of this engine family include a standard bore that is .110" bigger than a 454 Chevy and decent enough stock heads to feed the cubes. These things crush sbc's in the hp/$ arena when talking about factory parts. But the pot is getting sweeter. Seems that none other than race engine guru Jon Kaase wants to bring the Boss headed Fords back to the street. In fact he is well on his way to bringing just such a beast to market. Please refer this thread for reference..... http://www.460ford.com/viewtopic.php?t=22965

    May I humbly reiterate that the Boss 429 is probably the most efficient factory 2 valve head ever devised to feed such enormous and hungry animals when speaking of gasoline as the chosen fuel. The secrets lie in the shallower (than true hemis) valve angles, quench chambers, lower domes for higher comp pistons, and superior "charge motion". No the Boss's potential was nipped in the bud so early into it's life due to the times it appeared on the scene. Thanks Mr. Kaase for developing a street version that will be obtainable by hot rodders and will adapt to the garden variety short blocks. This is good news for Ford nuts.

    Two F--King crackheads broke into a storage trailer & stole my dad's BOSS429's. the motor was apart and stored. More than likely they it for cash.

  15. They certainly did. One of the sets was entered in the Engine Masters contest and did very well, considering it was a semi-lowbuck effort. They are certainly not the only Boss-type heads out there, but they are special in that they are essentially factory-type replacements which can use all the original components, except for the rockers, which are better than the originals anyway. Basically he fixed all the flaws and annoying characteristics, improved the air flow, and built 'em. ;) The power figures from the first sets were astounding, given that the test engines were really fairly mild by today's standards.

    I got to see the prototypes in early 2008, which was very neat...I have pictures on my old computer, but haven't moved them yet. I tried to talk him into making new 427 SOHC pieces :D, but no luck there, and a couple of other guys have done them since.

    Kaase bought a 2008 Mustang GT and made a modern-day Boss 429. It was amazing to see that the 429 fit almost perfectly in place of the original 4.6 modular engine... http://www.460ford.com/forum/showthread.php?t=119686 I saw the completed car in Jan. 2009 and it was completely cool...new car or no new car.

    The car has since been sold to someone in Canada IIRC.
