Limited Mod Animal Help


New member
Anyone know the legal limitations on building a limited mod animal? I have a new block just itching to be put together but im not aware of the wka rules on bore, stroke, cam, and valve size. Looking to have the parts ordered by the end of the month so any help on this would be much appreciated.
Bore, stroke and valve size is stock. Cam .307 lift at valve, cam duration @.050 248 degrees max @.200 153 degrees max. stock rocker arms, push rods. HL tilly. Lots more rules should get a book.
