    not my first boosted car, not even my first boosted Buick. I got addicted back when turbos were terrible - with a 77 Skyhawk that had a 79 turbo Regal motor in it. Draw-through FTW baby! :blast:power shifting a dogleg 5 speed with 3rd popping out of gear when you let off the throttle - good times, really hazy good times man. And despite all of that (it died when the turbo lunched) I miss that car a lot....

    Awesome to see another Efi forced induction project. I feel your pain over the machine shop. I got screwed by my machine shop as well. Its tough to get the motivation once you hit a roadblock like that but it's great to see you are getting back into it! Don't add up the costs because you can certainly buy an LS cheaper than building a Buick motor. There is no fun in that though.

    It's just part of the story of the car, now. :cool:

    so it's in the shop
    for those who wonder why I finished the '40 first - to pull the buick into the shop

    and firewall holes

    and I made an executive decision - I'm going to put this on a frame table to weld the floors in.... nothing like an extra 40 hours of work... oh well, only way to do it right

    Of course, it'll be a slow start because I have quite the honey-do list that I postponed while I was building my FJ40.... but I hope to do something each day....

    so I may back up just a bit.... when I built this, I was more concerned about tuneability and straight line performance. I'm not putting a cage in it, so it needs to turn as well.... which is better accomplished by a triangulated 4 link rather then the 4 link with panhard. Also, it drives and rides better.

    so, the parts


    kind of the back story is I also need to narrow a 9" rear end and I'm not sure which one's going to get the cut.... but that's a tomorrow deal

    thanks guys - I really appreciate those who cheer the build because there's lots of times I look at the amount of work and wonder what's wrong with my head.

    It is a challenge but keep on going!

    So I bought these air springs for something else, but they're being pressed into service while I decide what I'm doing with the back.... problem is the mongo tires may interfere with the triangulated 4 link

    but for now, they'll hold it off the ground so I can more easily roll it around

    Buick approves

    I realize I haven't shown the car that I fell in love with (even though it's caddy powered) and commenced me on this path

    however, it will be closer to this when it's done

    with a whole lot of inspiration from this

    that's a good looking 4 legged shop helper you got there.

    Cool thread, looking forward to the headers you build for the turbo (if that's still the plan) :)

    that's Buick middle name Dipstick he's working on getting up the courage to be in the shop when dad's working. Other then when dad's in the shop, he's my attachment. Some dogs orbit you, some dogs don't come when they're called, some never leave your side and always must have one point of contact.... the last is Buick

    oh yeah stainless, turbo headers are coming.... but first I need to set where everything goes. While there's a lot of room front to back under the hood; I suspect that it would be tight fitting them next to the motor

    been a week of cutting the floor out and making sure the body doesn't collapse to the floor.... I have a plan, but it involves moving most of the shop.... when it cools down a bit.first, catalog the damage (I should just take one picture, there's damage everywhere)[​IMG][​IMG][​IMG][​IMG][​IMG]more carnage, later.‚Äč

    Oof, that's a lot of work, but wholesale repairs on the flooring certainly makes it easier to fit the new drivetrain and suspension.

    pretty sweet! what are you doing about cylinder wall thickness? Same issue medium power ls1/2/6 blocks high power iron 6.0 LS engines have is splitting the cylinders vertically below the deck surface. ive tried to think of a way to make a "form" inside the water jacket to support the major thrust side of the cylinders with hardblok but the water passages are so few and far between on the deck i don't know if it would be possible. My other ideas would be actually "de-boring" the engine and having a .120-.150" repair sleeve put in a virgin block taking it down to about a 4.200-ish bore but way thicker cylinders.
