Weld those Subframes in it will be a lot sturdier. I like my 70/30's but with the extra weight of a 351 I would go 90/10's in the front. The skinnies not only free up weight in the front they also free up a lot of drag, and are worth it at the strip. Yank that front sway bar also, it will hinder the suspension from working at it's full potential.
