Finally decided to bite the bullet and go with the LT4 instead of the LT1 (at the GM showcase at Barrett-Jackson). The most powerful stock engine that GM has ever built.

What I lovingly call the “Flat Plane Plenum”, if you look closely you can where the fuel injectors are located, halfway down the cylinder wall.  This photo shows the high-pressure fuel system.  72 psi from the tank into a mechanical fuel pump that runs off the cam, 2900+psi into the engine.

These are shots from the Factory’s 1970 Camaro build that I saw at the Grand National Roadster Show in Pomona, showing all the tricks they used to get things to work.

First off there is no provision for hydraulic power steering because all of the LT motors use electric power steering and there is virtually nothing on the market right now (03/19/2016) that fills this gap other than Dirty Dingo.  After spending several hours on the phone with the factory reps, they told me the prototype engineers built a 3D printed part and that’s what you see.  They used a conventional GM type 2 power steering pump and added it to the serpentine belt system using a longer micro-V belt # K080893.  If you look closely at the picture (click on it to view full size) you can just barely ready the part number.

They also seemed to have hacked up the original heater core sheet metal and replaced the front panel to get the new E92 ECU in because it appears to be much larger than the ECU for the previous LS based engines, we shall see.

They come bare from the factory so you have to either powder coat or paint them yourself.  This 2016 version uses C7 Corvette cast aluminum upper and lower A-Arms, no other manufacturer uses these pieces other than GM.  The spindles are C6 because you have a much wider array of brake options.

Bare frame with suspension removed, ready to bolt back in.

Front cowl cleaned up and welded.  First rough bolt in.

I chose to use sold body mounts instead of the polyurethane that I had in their before.  We’ll see how rough the ride is once it gets out on the road.

Suspension back on and 14″ – 6 pistion Wilwood disc brakes. All the bolts are this new OEM style that or zinc plated overlaid with an aluminum coating.  They are also a crush nut which means that they take some serious wrenching to get them on and produce considerable heat when you’re tightening them.  Morrison specifically warns you about not by-passing this part of the build.

Final cross-check to line things up.  There are two large holes right next to the front bolts that allow you to stick in a long spike alignment tool and push or pull to get things lined up.  This is how they must have done it on the factory production line.  For more detailed information about gen 1 Camaros, spend some time on www.camaros.org, it’s a fascinating insight into the early days of production.

 

1968 Z06 Camaro – Deconstruction

After 5 years it’s time for a change, so this winter’s project is the new Z06 LT4 crate engine and Morrison front clip. Off came the hood, fenders and the front end so I could begin to remove the front clip.

Speedtech A-Arms, QA1 coil-overs and a Hotchkiss 1 3/8″ inch hollow swap bar.  350hp modified 327 with a Tremec 5-speed was removed and sold off, as was the entire front clip.

Atomic EFI, which I also sold off was kinda O.K, I wouldn’t spend 3K again and do it because of how good the LS and LT engine run, there’s just no comparison.

Unisteer rack and pinion with Wilwood 6 piston – 12″ rotors, they were a bargain.  This picture really shows you have much caster (4 1/5 deg) that Speedtech build into their arms and it makes a big difference on these older cars, you just can’t dial in modern steering geometry with anything close to stock a-arms.

1968 Camaro SS with 327 (SS’s never had a 327, only the RS).  There is so little difference between models, in some cases it’s just trim or minor options.  This car was just a simple V8 model, that was neither SS or RS when it started it’s life in Van Nuys, California.
