  3. The "Group Buy" for the 1967-68 Deluxe Steering wheel recasting is now officially "Open". Now is the time to start sending in the wheels. The latest date that the wheels must be received by Kochs is 31 March 2025 The cost for each wheel is $750. The only "up front cost" is your shipping the wheel. If you send in more than one wheel, each additional wheel will cost $700. Shipping and insurance to Kochs and return shipping will be extra. You will be contacted by Teresa to make payment for the wheel(s) and return shipping and insurance when your wheel(s) is complete. The shipping will be factored on your delivery address and insurance. I will be sending the contact information all of you have sent me to Teresa at Kochs. Send in your wheels, horn pad and hardware and paint color sample if applicable.

    You mean what the induction system allows, with the cam complimenting that?

    Nice looking project BTW.

    I think the big deciding factor for where I make my power will be the almost stock heads. Its kind of contradictory for me to have a single plane intake with a spacer on stock heads and a low rpm cam. I figure since I will be going with forced induction and plan to make a relatively small amount of power on boost, I really don't need to try for every last bit of NA power. My rods will fail or I will blow a head gasket before I run out of potential for more power. I am curious how this will perform without boost though. The single plane probably hurts power a bit, but I make a full point of compression more than my previous motor. I also have a tame roller cam that should make plenty of torque, and power up to 5000-5500 rpm. The fuel injection probably won't help power too much, nor will the Distributorless ignition system, but it will make turbocharging much easier. I think out of fear of disappointment with NA power I went 4.11s, looking back I should have gone with 3.55s or maybe 3.42s

    Please excuse the poor shape of my car. Bodywork or a replacement shell is next on the list...

    That's AWESOME! Your car body looks fine to me, even more you did distributorless ignition AND fuel injection:TU::TU:

    I shouldn't have ended my comment with a question mark.
    The way your engine behaves is almost totally defined by the heads, with all of the other parts factoring around that, boost included.
    I didn't mean to split hairs with your comment that implied that the cam determined much of the parameters, but it struck me as odd.
    Nice car.

    No split hairs here! I appreciate any comments or advice. I still have a ton to learn, so I'm glad to have guys like you around to help out.

    In the end, I know I won't be making big power with the motor off boost. If I went 13.99 at the track I would be thrilled, that would best the old motor. As for where I make power I guess I really won't know until I'm on a dyno, which very well may happen at some point before forced induction.

    Randall (thesilverbuick) is the resident EFI expert here on V8Buick. I used a lot of his methods and ideas for making EFI work on my engine. One of the few unique things with my build is using the GN cam sensor as I dont believe that's been done before. It's an athestically pleasing way to add a cam sync, easy to buy at any autoparts store, drops right in with no modification, and it's a Buick part which is cool.

    Using the Holley EFI system is another thing our builds differ on. One thing I regret about the Holley is the cost. They have so many add-ons that are needed even for basic builds that the cost gets out of hand fast. Even after all this, when I go turbo I'll have to spend even more money on boost control solenoids and maybe a new ECU as the one I have has only 4 inputs and 4 outputs.

    The budget EFI systems out there are really the future. It will get harder to justify a $500 carb when you can have efi for $850. My friend has an MSD atomic system on his 351w and it runs awesome. You answer some questions and set a few things and you are done. It fires right up every time. Its downside is the lack of datalogging, and no ability to add on gauges or a larger screen.

    As for my car I might have skipped over the bad parts during the video but there's holes in places. One of these days I'll make a decision but for now it will be cool smoking people in a beat up old Buick haha.

    Reading through this whole thread, it pains me that I just parted out the car. I've wanted to do it again from the moment I sold the engine, and hopefully I can start on that project this year.

    I'm on the hunt for an 80-84 Park Avenue. Going to look at a super rough 80 this weekend with a running Buick 350 in it. Figure it could be my test bed until I swap it all into a nicer car...

    67 GS400, 85 Corvette, 59 LeSabre, 85 Celica. Sure. I need project another car.:rolleyes:
