Waiting for new pistons and crankshaft

Most new parts are in house (ordered from Summit Racing in US). New pistons and crankshaft are ordered locally from Polly Motorsport (which again get parts from US). Polly has quite a reputation as engine builder. By his experience in choosing the right pistons and crankshaft I will get the right rotating assembly for my engine. The rotating assembly is still in US for balancing before shipping to Norway. The engine block is the only part left from the original engine - all other parts are new (MSD ignition, oil pump, water pump, rotating assembly, bearings, camshaft, heads, new camshaft timing chain and gear). New pistons will raise compression ratio from stock 10.5:1 to 10.8:1 due to a smaller combustion chamber volume (54cc).

This is how the engine compartment looks like now - a big empty hole. I will spend some time to label remaining unlabeled contacts and check all contacts. Cleaning and paint is done.

Below are pictures of new parts in house. The most exiting part is the Tric…

What next ?

So what next? Engine and trans are pulled from car. Trans (700R4) will be sent away for maintenance and strengthen. Trans must be able to handle about 500 HP (engine). I have never pulled an engine from a car before. Some 25 years ago I worked as chief engineer on board RNON fast patrol boat. During those years there was a lot of work on big engines. For the last 20 years I have been working in office. The only time after from navy I was a "mechanic" again was during my 8 years as a hobby road racer beginning of 2000. The picture above is from a race in Sweden riding a Ducati 748R. Fantastic motorcycle and it was "seriously abused" ( I had some serious crashes on that bike).  
Doing some serious work on my Corvette is fun. I do enjoy my time in the garage working on my Corvette.
Engine and trans pulled together. Some logistics about bolts and connections is a good idea when pulling engine from a Corvette C4. Label connections and use smal plasticbags and …

My first blogpost

Commencing blog

This is my first blog ever ;-) I will blog in english (my native language is Norwegian) and my subjects for this blog are mostly technical from car (Corvette C4), computing and photography and nature. The main reason for commencing this blog is mainly because I have just started a major upgrade of my Corvette. The plan this winter (2011/12) is to get some more power from my engine. The engine is a standard LT1 V8 350 cid (5.7 l) Chevy GM Corvette. The car has done about 126.000 km and to be sure the engine and transmission are capable to handle the extra power a fully split and rebuild is required. Brakes will also be upgraded to handle the extra power.

“As built” Corvette C4 - 93 model
