289 vs 318 ..... Ford vs Mopar

Honestly, I think that Ford, Chevy, mopar all have good engines that have potential in making power. I think it all comes down to personal preference and what you are wanting to do with your car and the budget you have to work with. It's a known fact that the mustang's of the mid to late 80's responded well to just simply basic bolt ons. A friend of mine had a 1989 mustang that ran a flat 14 et and he only had bolt ons, 3.55's, cat back exhaust.
Some truth, but some is fact. For sure they can all be made to be fast !! I think from the mid 1980's on down, it mattered what brand you bought for durability, and reliability. Personally, I've seen more small block chivies with rods hanging out the oil pan, and none on any other brand. I'm talk'n stock short blocks.
