289 vs 318 ..... Ford vs Mopar

Actually, I don't recall 289s? They may have differed than 302s. 351s definitely had this issue. That I at least saw? (Shouldn't assume Ford small blocks are all simular. I never understood their thinking of "Engine Families" they had 4 different versions of 351. None were directly component swappable. And of course their 352. Which was completely different.)
Had a 352 in a HD Ford 700. They are not the same as a 351 C. The 352 was a work horse and the 351 ( 70' cougar) was a street burner. I do respect the SB 289 ford motors, 283 chevy as well as the 273 Mopars. Just a bunch of fun SB motors, but the 340's rule in their placement in the A-Bodies.
