This approval gives you full access to the site, to pictures, and to post, among other things. To be able to enjoy the full potential of the board for you, you need to be fully registered.. and that's easy.. Just send an email to me at jim@trishieldperformance.com and I will verify your registration. This policy will remain in effect indefinitely, as it has completely eliminated the bad actors from our site, who would spam and hack it, once they gained access. Thanks JW

  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. Please include: First and Last Name Shipping Address Phone number email address V8Buick "Member Name" Wheel Color (SEE THE BOTTOM FOR WHEEL COLOR) Pease read the "shipping to Kochs" below. There are two addresses. One for USPS Mailing One for FedEx and UPS shipping You can use USPS/Mail, UPS or FedEx to send in your core. Use the appropriate address depending on what service you use to ship. If you use USPS/Mail ship to: Koch's P.O. Box 959 Acton, CA 93510 Attn: Teresa If you use UPS or FedEx ship to: Koch's 7650 Soledad Canyon Road Acton CA 93510 Attn: Teresa Kochs Contact: Teresa (661) 268-1341 customerservice@kochs.com Wheel Color If you wheel is Black, you can list that in your information you send in with your wheel. For colored wheels, please contact Teresa about specifics for wheel color if you do not send in a color sample to match. Please contact me if you have any questions. Thank you to everyone for your participation in making this a reality. And "Thank You" Jim Weise, for allowing and facilitating this project!

    They claim to be accurate within 5%. It's a good tool, but I wouldn't trust it.

    Although, according to Dyno2000, the TA Stage 1 aluminum heads are worth over 100 hp as a bolt on:Brow: I'm guessing more like 60, but STILL!

    I beleve if you put in all the right data you should be very close. Especialy the head flow numbers, cam timing and compression ratio.

    I can offer only this.. from actual testing..

    Chris's specualtion that the Alum stg 1 heads are worth 60 HP is correct..

    I have built two almost identical motors, with only the heads being different.. one with 250 cfm ported iron heads, and one with the aluminum heads.

    The difference, equipt with the same carb and headers, was exactly 60 HP.. the only difference in the motor, was that the one that was built for the aluminum heads was a full half point higher in compression..

    So just the heads alone, might only be 50 HP..

    But it's no where near 100 HP..

    As always, the total combo needs to be correct, to see the most value from a major component or airflow change.

    For those of you truely interested in a reasonably accurate computer simulation program, I suggest that you check out "Engine Analyzer Pro".

    Just today, since I am considering doing some different stuff with camshafts, I was searching the internet, for the info on this program, which has been reported to me as the most accurate sim program out there.

    But with a pricetag of almost $500 for that program, I guess I will just have to figure the overlap @.050 out on paper, since that is all I really wanted the program for.

    Jim, Dyno 2000 will give you over lap. It also has a cam calculator. If you want too PM me the specs and I can get you what you need.

    Desktop Dyno/Dragstrip predicted the best ET on my last car exactly (13.55)
    We discussed this at length a few years ago on George's mailing list, and the consensus was that it was pretty accurate. Of course, GIGO always applies.
