Todd the 429 will go in Galaxies or fox chassis or fairlanes or mustangs after 66. Dont expect to get all that 500 horses to the ground with any of these stock chassis tho. The factory purpose built cars to limits, but if u can stand to have a measly 350 hp or so u will have a car that will be safe on the streets and fun.===rdhotfrd oh if u need a 64 Galaxie body i got one.
