Engine, Engine Accessories, Cooling, and Exhaust -

When it came time to choosing the engine setup, I knew it had to meet the following requirements: 

1.  Big block (easy power and less common)
2.  Around 475 to 550HP, 525 - 600 ft/lbs torque.  Nice rumble but still very street-friendly.  No more power than that because I'd have no way of transferring it to the pavement with my street radials and I don't want spend too much time at the gas pump.
3.  Carbureted.  Maybe fuel injection later down the road(those Hogan units are gorgeous), but keep it simple for now.
4.  Forged bottom end, aluminum heads
5.  At first, I was just going to build my own engine as I have built 2 big blocks before and I enjoyed the process.  However, after spending weeks pricing out different scenarios, I realized that it would cost me nearly the same to build my own engine as it would to purchase a GM crate motor.  By purchasing the assembled crate motor, I wouldn't have to worry about clearances and I'd get a warranty for basically the same price.

So it came down to the GM ZZ454, the GM ZZ502, and a few others.  At that time, it seemed like a lot of people were using the ZZ502, so I didn't want to be just another Camaro with that engine, so I decided on the ZZ454.  People had a lot of good things to say about the engine, I think it met my needs perfectly ,and it didn't seem so common so I went for it.  After receiving the engine, I did the following to it:

1.  Replaced the oil pan and oil pump pickup to fit the 69 Camaro
2.  Painted the engine in high-heat blue to match the color of the car(as best as possible)
3.  Ordered the GM 'Chevrolet' aluminum valve covers and had them eventually painted with matching body color paint
4.  Designed the engine compartment to be as clean as possible by re-routing hoses and hiding electrical wires
5.  Used a lot of stainless fasteners, hose fittings, and billet pulleys and brackets
6.  Purchased NOS Big block 69 Camaro motor mounts and transmission crossmember to ensure a guaranteed fit

Other than those highlights, here are the details:

Engine and accessories        
Component Description, Part number, and Source Price   Opinion
GM ZZ454 From Summit Racing, includes shipping to my door, unloading to garage 6375   So far I've had some difficulties getting the engine to not have a slight bog
ZZ 454/440  Technical Information     when I hit the accelerator hard.  I've tried 3 new carbs, different plugs, 
Horsepower 440 @ 5250 RPM     different timing settings, new wires, stock ignition vs. MSD 6AL, and 
Torque 500 @ 3250 RPM     different squirters and cams in the carb.  I've gotten a lot of the bog to 
Max. Recommended RPM 5500 RPM     go away and it's close, but I still can't get over the hump.  The engine
Compression Ratio 9.6:1     also runs a bit 'rich' and feels like it's only running at about 70%.

Cooling System and Hoses        
Item Description Price   Opinion
Radiator  Ebay, Aluminum Radiator for BB, with heavy duty tranny cooler 366   Fit great.  Very happy with it.
Fan GM 18 1/4" seven blade, Classic Industries G8354 84   Still the best bet.  Electrical fan setups are expensive and overrated.

Headers and Exhaust        
Item Description Price   Opinion
Headers Hedman 66001, ceramic coated, Summit, 2" primaries, 3" collector 485   Gorgeous headers.  I have very easy access to my spark plugs
      which I'm very happy with considering the primary tube size.
      Had to ding in 3 locations:  2 near the steering box and 1 on passenger side.
       
Exhaust system Flowmaster American Thunder, 2.5" Header-back, aluminized, Summit 292   Not so sure about these mufflers.  They sound okay, but I think I might be
FLO-17129(67-68) doesn't have long & ugly stainless exhaust tips like '69     able to do better in the future.
Comes with DeltaFlow 40 series mufflers      
       
Different mufflers, larger/quieter Flowmaster 50 Series, Stainless Summit FLO-842551 212   A little too big.  I could get them to fit, maybe, but it's very difficult and I
Didn’t fit well so I sold on Ebay for $160 -160   couldn't use heat shields which were very important for me.  Maybe the 
      larger-than-stock driveshaft didn't help either.
Header Reducers Hedman HED-21112, Ball and Socket Flange, 3 in. Inlet, 2.5 in. Outlet, Aluminized 25   Not sure why they gave me such small one with the headers, so I had to 
      order these.
Muffler Heat Shields Flowmaster Muffler Heat shields, reduce cabin temperature drastically 55   Worth every penny.  Greatly reduced floor pan temperature.
