I've seen that video.
Remember when i was complaining about no working room and suggested buying a b body with a slant six only?

When he said the a body was never meant to recieve a v8 and the b body is just a somewhat upscaled version of the a body it explained at lot for me.
The platform was just never meant for a v8 thus stuff is hard to reach compared to a 70 chevelle ls6 or 71 442 W30 for example.
That of course does not take away from the fact that chrysler engines (especially the 426 hemi) are great and the body styles are second to none.
