I have always been told there are Slant six K members Chrysler small block V8 K members and then big block K members and a 426 Hemi member. I was just told they only had slant six and v8 k members. This guy also told me I can drop a 440 right in my 74 Challenger Rallye four Speed that is a 360 k member. Is they any truth to that. Has anyone on here done this.
