Engine Test, Completed GM 253 4.2L V8

This is my completed GM 253 V8 project engine. I learned plenty building this from the ground up, it now runs perfectly, very nice burble with a complete exhaust system fitted... or otherwise with straight pipes as shown here :-)

sounds like a bubble machine

[BigMaxTube]

@2nvabs Yeah, i've noticed that sound too on other vids of engines running with no exhaust... even little single cylinder types. Thanks for looking and commenting

[intheshitter]

Oh ow.. the "whoop whoop whoop" sound reminded me of my old VB/SLE that I had 12 years ago with the same engine. IIRC that sound is the mechanical fuel pump??

Man I miss my VB. It was a 79 model yet it had AC, power windows, power steering it was mint.

[BigMaxTube]

@intheshitter Yep, that odd sound was from the mechanical fuel pump.. probably 'cause it was running dry

[digitalrailroader]

is this the Same block you used with your other Videos?

[BigMaxTube]

Yep, it's the same engine, when completed. It now has a clutch and 3 speed syncro gearbox fitted to it. All I need now is a suitable chassis to fit it to :-)

this poor engine is being sufficated, my god take that crappy air cleaner off it and put a high flow.

@chomby1991991 You won't have to move the radiator, as in all Holdens, a V8 sits "two cylinders' worth" back from the front of where a 6 cylinder would be in the engine bay. The main problems you will have are "do I have to cut the inner guards to clear the exhaust?" and "is this driveline strong enough for a 253?"
