Re: Are Mustangs still collectible?
What structural upgrades were on these mustangs with the factory 390 option? If a '67 will accept a 390 it should accept a 351. I also wonder how much more weight a 351 is compared to a 289? The bore is the same, longer stroke and taller deck height. Similar weight as a 289/302 if aluminum heads and intake are used?
