I really hoped someone would have responded to is post. I was wondering if the Stock WS6 package was a good enuff to build up on. Don't think I'll bore my motor that's was jus rebuilt, I have another LT1 block ima dress like that but all the common sence bolt on's are goin on the rebuilt mother until my other block is dressed.....jus wondering if I should upgrade suspension now or if its durability is fine for all basic bolt on's. I'll check back an see wat you come up with.
