Very nice

Dan@SharkWerks

Glad to help with the Florida scene!

Thanks FFaust and glad you enjoyed it. I had to narrow down about 300 photos to reach this number, but it's fun to see what we come up with in the end.

Ahh yes, we love these cars. That helps get through the slower days.

Sure thing and we will keep em coming!

Thanks Lopro, the next batch of photos should be a bit new/interesting stuff. I think some people might use our threads to assemble the bulk of their cars themselves. Of course we don't make it that easy, but at least we give some reference points and people can see what the internal bits look like since they're so well hidden when the engine's in place.

Thanks guys, we had fun w/ the shark!

Thanks guys and LOL at the hood badge, I think it's quite unique and definitely adds character to the car. It's carbon too (weight savings!)

was that the white w/blue track rat from the bay area that seemed for sale forever? if so, did it sell? as i recall it was a little pricey which may have lead to it sitting a while

Come on Cameron...first you get just plain fast, now a 3.9? You're killing me man!!!

Great pics!!! Keep them coming!
There are going to be more & more 3.9L conversions so guys can stay close to a 4.0L & keep their cars fresh: another new mod.

For me, this will be the exclamation point at the end of the long list.

If Robs GT3 ends up anything like his 993 did, the local GT3 cheater crowd should be scared!

'displacement wars' have begun

With the 50k+ miles, the valve guides have excessive movement, especially on the exhaust side, and since the stems are only 6mm, we opted for a refresh of the head. New valve springs and guides, along with a little clean-up

freshness

On the home stretch now. As stated above with cars with high track miles when doing an engine build it would be wise to have the heads refreshed. This includes a nice jet wash, clean, polish and resurface (cylinder heads will have slightly higher compression), resurface the intake and exhaust valves and replace the intake and exhaust guides with honing for proper oil clearance, cutting of intake and exhaust seats. One thing you can also do is use manganese bronze guides that will last longer than factory:



Re-assembly continues with our 3.9L pistons, liners and our ring package:


One side in:


Assembly with the water jackets and cylinder package is a precision process requiring some factory tools as well as our own:



We also use our non-factory head gasket which is set up for the larger bore:


Installed and with our larger bore we use steel liners for strength:


On go the refreshed heads (with new springs too):




And assembled (there's a special torquing procedure here too):


Seal this thing and leave to dry over-night:


Almost ready to start installing the lifters:


In they go:


And the SharkWerks spec cam shafts are next:

You have no idea how bad I want to do this... The GT3 DE Cup Series would be turning into a nuclear arms race.

Thanks for the photo work -- gorgeous machinery.
You know, if you do enough of these 3.9's, sooner or later, you'll get to be pretty good at it.
