    I've submitted earlier posts about a 4" sus. lift, but I wasn't fully thinking at the time. (I only have time to check the forum at 5 a.m.) But, I have a 454 in a 1984 k5 and, with the extra weight in front, what would it take to make ol' bessy level & 4" taller?

    I know just enough to know that I'll never know enough.

    I have been told numerous times that Big blocks are only 150lbs. heavier than a small block. That isn't bad.

    I run a 454 and have installed two brands of 6" lifts in my K5. They both sat level with the rear. I also have a Warn 12k winch in the front. No extra mods where made to the front springs or perches.

    Dude, I think the heavier engine would do you a favor. Blazers are usually high in the front after a lift...I think a BBC would level it out and make it look nicer.

    Yes 73K5 you are right about the front pookin up abit more after a lift is done to a K5 and the reason behind that is cuz most all spring packs are designed by using the weight of a PickUp and as we all know the Blazer's rear is MUCH heavier than a P/Us rear! So when I put a new spring pack in the rear of my K5 I bought a 5 1/2" rated pack and 4" rateing for the front and my rig sits darn near perfict with mabie a C hair higher in the rear if you stare at it long enough! anyhoo don't think the BB would make that mush of a diff.!

    MINE SAGS!! The rear end sags just an inch lower than the front. I'm going to buy 2 more add-a-leafs to drop on there. I have 4" blocks and supposedly 2" add-a-leafs. YEAH RIGHT!! I think you will be ok. I'll hopefully get my Jimmy on here soon and you can see what I mean. Later

    Blzr4x4ngkid,

    Why don't you add a rear 4"shackle flip for $150 and then add a 2 or 3" block to get your ride level. It would ride a lot better than the add-a-leafs. Just a suggestion.
