Dear Volvo Enthusiasts out there, behold! I decided to open up this Tribe to set a place for discussion, repair help and experience about this mesmerizing engine. I myself own a Volvo 164 that I'm restoring this winter.
The B30, as it was used in every imaginable way, i.e. as car engine, boat engine, stationary power generator, in sports cars (Marcos GT) and of course as military vehicle engine, started it's life as a B18, that was bored out and got added by 2 cylinders. A camshaft on the lower side with spur gears and 2 valves per piston tell us that this is an engine design from the 50ies. Starting its production in the later 60ies, this wasn't quite state-of-the-art-tech, but this was one hell of an engine to last longer than its owners. It's an inline-6 that is a blast to ride, not only because of the torque it delivers. We have got the epitome of swedish "lagom" right here: Relaxed, powerful and sustainable all in one.
Especially the B30A, a double carburettor wasn't quick either, in fact it delivered only 131 DIN-hp which wasn't even much for a 3 liter engine back in the 60ies... The B30E with Bosch fuel injection helped a little when things got up to 160 DIN-hp, but there still was a thing called gas consumption. 15 l/100km for the manual versions of the 164 and up to 20 on the fuel injected automatic version.
So why exactly is this thing that great? I'll tell you: It's a very versatile machine, used in all kinds of places where an engine is needed. You could easily swap a Volvo Penta B30 into a car and vice versa (Yes, quite a bit of work, but managable). The basic design of this motor is identical to the one in the legendary P1800 of Irv Gordon (Who sadly passed away a while ago :( ) which made more than 3 million miles. These things are indestructible! There are a lot of 1´64s out there with over 600k km without a complete revision. Remeber: this engine is from a time where it was rather usual to have your engine revisioned after only 60k km...

I hope to find people here that think the same about this engine to exchange our impressions and to open up our trick crates to each other.
