Diving head first into a few motor builds.

Trying to do it right.

I figured I'd ask around before approaching a machine shop.

Thanks!

Learned something new today.  Never seen one of those.

What would it cost to machine one I wonder?

I wish one was available to rent within the Z community. I would be willing to pay a high deposit to rent one. It's one of tools that you really should use but will not use much.

~500-600 locally.

I'm looking at one of these ~450 and probably better made: http://www.ccaracing.com/product1.htm

Those guys say they rent:

 

We also Rent Torque / Honing, O-Ring and Pressure Test Plates!

I wonder what justifies a mandatory use of such plate. They suggest using them for all over bores and honing, but you know very few shops are using them . I imagine the larger the over bore the more necessary it gets

I've wondered they're not used on the head.  Cam swaps, tower alignment, valve guides, stuff like that.

These guys have them - http://www.bhjproducts.com/bhj_nav/nav_honePlate.php

 

I think that they cost a lot.

Kurby, CCA are just making their first L28 plate next week. I may purchase it.

Steve yup the machinists have measured differences with and without the plate installed. Newer techniques even pump the block with hot water to operating temperature. I plan to do quite a few 88mm and 89mm over bores over the next few years and sell some motors so it is a needed investment.

ZH, for the head, the cam can be relieved by the tower bolts when it is torqued to the block. Not much else can be done w/o a long boring tool and boring new towers when installed on the block or over-boring and sleeving existing towers. Yup BHIP are très cher ($$$$)

Will you need 2 sizes, 88mm & 89mm?  So two plates?  Curious

Cliff,

I would think one plate does all

So you are looking for a torque plate so you can provide it to the machinist? Not because you are using it at home...
