1980 Chevy truck V8 install progress

You would think that replacing a six cylinder engine and installing a V8 in a vehicle that was originally designed to host such an engine would be easy. Well, it IS easy but there are several items that need attention: Wiring, cables and other fitment issues comes up and have to be dealt with.

Wroom-Wroom! (automotive technical term) Chromed up Chevy small block ready to go in.


It became quickly clear that the flange on the “stainless” headers were not so…ahem…stainless. The manufacturer just welded the tubes to ferrous metal flanges and called it a day…or night depending what time it was.

With the sharp laser cut edges and total lack of corrosion protection all you have to do is walk in to the garage and mention the word “moisture” and they would start to rust.
Maybe to the Chinese manufacturer or the US importer “stainless” just really mean “partially stainless” Hell, it could be a cultural thing that I should really respect.

Also, based on the location of the flange bolt holes it is also very clear that Chevrolet small blocks are smaller in China. Looks like about 1/8 of an inch or so. Maybe they shrink during ocean transport? You know, just like cereal settles in the bottom during transport.

After several hours of filing and grinding the headers also fits the American small block.

I radioused the edges and painted the flanges black. I can’t have shiny stainless tubes attached to rusty flanges.


Since the hood was off I thought I will clean it inside and out.

I friend said that I am going down a slippery slope by polishing the 33 years old one step GM metallic. You know what…he is right. Short of clear coating the paint it will dull again. However, my OCD takes over and I can’t leave it alone. So after a polish it’s time for a real world challenge: On the passenger side: Meguiars “High Tech” Carnuba wax and on the driver side we have Nu Finish Polish. We will expose this truck to a wet and crappy Washington fall and winter and we will see if there is any difference.

After the polish and wax it is almost as shinny as the shiny 1937 Ford in the background.
