thats a big small block
That is some interesting history. Even larger impact to the horsepower wars when you consider the aftermarket and the hot rodders diverting their attention between Y-Block, FE, Windsor, Cleveland, and 385 while the Chevy guys focused on SBC and BBC (with common bellhousing and engine mounts!) in the same period.btw, just to repost this info here too as some guys don't know about FORDS 1966 XE #93532 351W 9.2" deck race block that was in development from 1966 to 69 that got bored/stroked to as big as 400CI in 68/69 for Can-Am racing just before it's development and racing got shut down.
A bit of forgotten history that may interest some guys, some of the public does not know there was a 9.250" deck 351 "W"indsor # XE 93532 race block made back in 1966 way before GM's B Kundsen's "C"leveland block was even on the drawing board & this 351w XE 93532 9.250" deck Windsor race block got as big as 398/400 ci (4.110" bore x 3.770" stroke) with 600HP back in 1968/69 for Can-Am racing. 302 & 351 windsor XE race blocks were tested with canted valve head prototypes in 1968 just before Kundsens new block was & there were plans WAY BACK in 1964-65 for a 9.450"+ deck 6.9-7.0L aluminum XE 94244 Windsor race eng for Can Am racing. IMO, with Kundsen taking resources away from the Ford engineers we might have even gotten a GT4VBoss 402 ci "W"indsor engine as the 69 9.480" W block was destined to become a 400+ci eng if it wasn't for GM's Bunkie Kundsen screwing things up at FORD with Fords XE 93532 351W race block development by selfishly ramming through his own "Oldsland" inspired block for the short time he was there. H Ford should of fired him sooner.
