The original ZL-1 block had #3946052/53. I was surprised to se this new number was ending with a "D", #394605D.
Does anybody know why its a "D" in the end instead of a "2" or "3"? My guess is that there is an issue with the owners rights or similar between Winters Foundry and GM....? Could "D" stand for "Developed"....or Dumbass...or Deamon....or maybe Doomed? :o

Come on now, guys....someone have a clue, don't´ya?  :P

Well, isn't much happening with the motor build right now but at least our motor shop has started to work with the balancing act! :)
He´s taking our ZL-1 between other projects and that's our deal....we rather go slow and correct then fast and wrong!  :P

Here´s one of the pistons and pin on the scale::




The old dot rods has gotten a deep clean and new bushings. He also has reamed the new bushings to fit the new pins to get correct tolerances. These rods are the type with full-floating pins.




After this each rod will go through a balance act, so to speak:


I´ll try to update here whenever new work is put in by the shop.....

Just a question - did the original floating rods have a pin oiling hole in the small ends ? I've never seen an original ZL1 floater, so I thought someone might have an opinion - or a spec.

I really don't know, Steve but these are probably not from an original ZL-1! The dot rods were used in a range of high performance engines such as the L88, ZL1 and LS7.

Here´s a close-up of the small end if this is what you looking for:

Went to the Motorshop yesterday morning before work and now the balancing act is done! I took the chance to be part of the final adjustments and it was fun though I´ve never seen this before.

First the pistons had to be fully weight adjusted within 1/10 gram. The pics below shows how different pistons had to be adjusted. Theese pistons from ICON were, according to Ulf at the shop, very good for being American parts! It differed 5 gram between all of the them in weight! Like Ulf said; - It´s god raw material for balancing!




Also the rods had to be adjusted within 1/10 gram and here the weight difference were 7 gram. Here they are ready to me mounted with new bearings from Clevite.


Here is the crank, with damper and flexplate mounted, balancing bench. The SFI-approved flexplate from SCAT were internal balanced from factory and Ulf was very satisfied with it.


The figures were 0,0 on the flexplate side and 0,3 on the damper side....not ok at all said Ulf!


After finding the exact right spot he adjusted, read used a drilling tool, the damper a bit and the figure went down to 0,1 which Ulf thought was ok!


Now even Ulf was happy!


This was probably the last update for this year cause other projects is knocking on Ulfs door but we´ll get back early next year for more updates!

We wish you all a Merry X-am and a Happy New Year!
