Awesome build thread! Really shows me what I'm up against with my swap (64)
I know is is backtracking a bit but I'm about to remove the oil cooler on my LS3 and really want to avoid messing the threads up. Any suggestions?
The next problem that needed to be resolved required the engine to be removed for the fix...... when I removed the original Camaro oil pan that had the factory engine coolant heat exchanger for cooling the engine oil........there was a fitting that fed the coolant out of the block to the cooler........when I removed that fitting , the sealant that the factory used ended up galling the thread while unscrewing the aluminum fitting........so ......the threads were screwed up in the block and needed to be repaired so I could screw in and seal the opening with a new fitting that I will make at the shop..........So......In checking the threads it ended up that GM uses a non standard thread.........M28x1.25 pitch...........you can get a 1.0 or a 1.5 mm pitch but not a 1.25.........so.....I had no choice other than to have a tap made by a specialty Tap manufacturer..........Now....Because the threads were galled in the block and didn't want to take a chance of the tap going in on a angle and making things worse.....I made a sleeve that was a slip fit for the tap so I could hold the sleeve on the sealing face of the hole ......this allowed me to keep the tap square ...............Held it in place and started tapping and I got Lucky as it picked up the existing threads and cleaned them out perfectly.......Cool.......I'll make a new fitting tomorrow and get the engine in for the last time ( I hope)........

If you need the tap to clean out the threads I can send it to you......Just return it when you are finished....

Thanks Ken! I hope I don't have to take you up on that offer though.
Any suggestions to avoid messing up the threads? I was thinking maybe a little heat and threading it out and back in a little at a time until its all the way out?

So......After driving this Beater all summer......Here are a few observations.......Starting with a #'s matching restored car was one of those should I or shouldn't I deals.........In retrospect, I wouldn't change a thing........The time and aggravation of doing the Body/Paint/Interior thingy was well worth the little extra cost at the start of the project........It might have been a little different story if there was shoddy workmanship involved, but...........that wasn't the case here.....Driving the car has been a blast.......basically it didn't miss a beat all summer (5500 miles).....as far as I'm concerned, It's the perfect blend of "Old" with the drive ability of all the "New" stuff (that's also what the GM guy's on the Power Tour thought and why they did the Feature on the car........ https://theblock.com/news/ken-tibor-...ur-feature-car The car never gets hot.....even with the A/C blowing ice cubes......Did I mention Torque.......LOL.....Now I know why Charley is always smiling while driving his Camaro..........

After the Power Tour was over........one of the regulars we travel with for the week is Steve Kranick who just started a Hydrographics business schotrods@Hotmail.com ...........Between Steve and my son Chris they worked behind the scenes and did a new engine cover to surprise me with as they hated that red cover
.........The finishing touch.......

Bottom line is your taste is like many others that love the old school look but want to fuse it late model performance.
Well done!
QQ and sorry if I missed this in the thread... What is your rear gear ratio?

Some of these guys are extremely militant and act as if you poured gasoline on the car, flicked a match at it and started square dancing around it.

The Season is just about over here in Wisconsin........Overview of the year since the completion in May......7276 miles of trouble free driving this year......There is still a few "Tweaks" needed to make the car up to the standards ..........The first issue I will be dealing with is the Oil pan / Drivetrain angle issues.........again......on the initial install the Holley 302-2 pan was not available so I used the -1 pan........I had to raise the front of the engine to clear the tie rod ends, which gave me a little more angle than I wanted.......to get the angle more in line I have the rear of the trans shimmed up as high as it would go to help out with the angle issue......In doing this the trans is hitting inside the trans tunnel and giving a slight vibration ........So....even though mechanically the angle is now dialed in.....I am going to change the -1 pan out for the -2 pan so I can lower the engine slightly to alleviate that issue.......
The second issue is the reproduction dash Pad in the car........Repro Dash pads are Junk in my opinion and don't fit worth a crap......I've been looking for a OEM one for months to send to Just Dashes for restoring........I finally found one and sent it off to them for restoring.......they have a twelve week lead time so that makes the timing about perfect.......I also bought a DSE wiper motor assy so when I take the dash out for the pad install I can change around the wiper switch and wiring.........
All in all it's been a real treat to drive this car around the Country this season......The Torque and Power these engines make is just Crazy...........along with the average for the season of 20 MPG are just outstanding .............
