  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!

maximum rod side clearance?

Discussion in 'Street/strip 400/430/455' started by TimR, Nov 13, 2003.

    I know the manual specs it out as .012 max, but the hot rod buildup was .018 and I have seen larger specs in other articles.

    Reason I ask is a I have a 72 455 that was a cheapo rebuild before I got it and one set (7and 8) specs out at .013 (tight) clearance....otherwise bottom end looks fine....I assume major concern here is oil (and pressure) loss from the rod bearings?

    later

    Tim, consider that rod side clearance as fixed orifice(s) in a flow stream- the larger the orifice the greater the flow rate. The increased flow will provide for cooler operating main and rod bearings at the expense of lower oil pressure as the flow rate approaches the oil pump capacity. In one instance, I ran across a set of Carillo rods in a BBB that measured .025" side clearance and required the HV pump to survive. Also consider any excess oil that will tend to wrap around the rotating assembly at RPM, making a crank scraper a must. I would recommend sticking close to Buick's max clearance unless you are considering some excessive bearing loads (hi compression, nitrous,100%+VE,ect) then you may consider opening the clearance up a tad. Good luck!

    I understand the theory but was more or less curious on what you could get away with on the BBB. I didnt thnik .001 over the limit would matter much, but you never know, thus the question.

    thanks
