Default Show Us Your Engines

There are numerous threads for our C3's classified for wheels, colors and builds.
How about a thread to show us your engines on the stand so we can see what we are all so proud of before they get dropped into the engine bay and all the work and components are hidden from view.
Just a couple photos with a list of components and what year C3 your dropping it into.
This is open to all make and model engines, full restorations, resto/mods or full performance.

79 L82 took down to bare block, used the stock crank, rods and pistons after reworking. Dart iron heads, Sanderson shorties, Comp XE268 cam, Edelbrock intake, Lars tuned Q Jet.

Really woke it up. 4 speed and 3.70 rear end, goes pretty good.

I say it all the time, goes to show what a properly built 355 can do and, in spades! With 3.70's you would be in the 12's...........................

My original '70 L46 350 block, bored .030" over, stock forged crank and pink rods, polished and resized, Dart SHP 180 aluminum heads, Weiand Street Warrior dual plane, sealed power hyper pistons, ARP fasteners, Howards retro roller, Scorpion rockers, roller chain, billet timing cover and fabricated valve covers. High-torque mini starter, completely rebuilt and re-curved original points distributor, rebuilt and tuned original Quadrajet carb and Doug's 1-5/8 long tubes with 2-1/2" duals, H-pipe and Flowmaster 40's.

I wanted an ultra-reliable driver with good street manners. 9.8 compression and it's all done at 5800 rpm. It dynoed at 392hp and 413 lb.ft and i am running a wide ratio Muncie with McCleod Super Street Pro clutch. Rebuilt the driveshaft, and just today finished installing 3" half-shafts and Bilstein HD's around the new offset arms and fresh 3.73 HD Posi rear to make it snappier than the 3.36 original. Waiting on my rear spring, then alignment and back on the road soon. Have not run this one down the strip yet.
