I have an offer from someone who says he has the dimensioned installation drawings for the marine version of the B30, the Penta AQ170, if he can lay his hands on them. I know those are dimensioned to the millimeter, but I'm not sure if it would measure to the bellhousing line.

Of course, he'd really be my friend if he had the triple-carb manifold that went on the AQ's...

The Volvo C303 was fitted with a B30. Rather more akin to a Land Rover so might be worth Googling for pictures.

Pretty sure they use to fit Holden 186 and 202 straight 6s back in the day in Australia. No idea sorry how they compare size wise.

B30 for sale on eBay, message the seller he might measure it for you:

Rover 3 litre P5 engine not your cup of tea? A common swap back in the day.
Factory six pots were 2.6.
Marginally less easy to find than a B30 though..

Comprehensively Googled, my son! Got a file of bright red engine photos as thick as your arm. Not one length measurement in the lot, B30 or AQ165/170 included.

Marginally???

The 3-litre is virtually unknown in this country except in a few specially-imported collector cars, never having been sold here (Canada, remember?) The 2.6 is only slightly better known, but there were only a handful sold, mostly in Land Rovers (I've owned some). The B30 is far more numerous, and I've owned a couple of those also. We had a Volvo plant in this town for 35 years. The B30 is more reliable, more powerful, and you can actually buy parts for them. And I like them. A lot.

The Volvo B30 is stronger more powerful if I remember right a little bit lighter, more reliable then the 2.6 and 3.0 BMC straight six motors as fitted in the Austin Healy 3000, MGC, Austin 3 Litre saloon.

Also more tuning parts like cams heads exhausts etc

B30 will fit in a series land rover, it fits in a P1800 see here https://www.glenngoodspeed.com/volvo/six-cylinder.htm

you could change the front to a defender or a stage one type front grille that will give some extra space if needed

That's definitely a shoehorn job for sure! Switching to a different manifold would have alleviated the crowding on that side. I really can't see room for the radiator in that set-up, but it must be there. I certainly like the concept, but the stupid boy-racer "wheel arches and wide wheels" look really spoils the whole thing. The Mad Max beer-keg/tank is a humorous touch. Possibly the stock fuel tank was too far gone to be saved.

Looking at this conversion reminded me of another question I have about interchangability between the B30 and the 4-cyl engines, but I've posted that as a separate thread.

Luckily, a flush-grille modification on the Land Rover isn't necessary. The one I rode in years ago still had the Series IIA front end. All that was required were some basic sheetmetal mods to the engine side of the radiator panel. You have to use the 164 rad anyway, and since it's wider, thinner, and not as tall, you can move it farther forward into the radiator panel without affecting the outward appearance. Flat-fronting a Series ruins the distinctive front end and reduces it to Defender status.

Correction: Just spotted the rad - in the exterior shot. Guess he wasn't planning on speed-bumps/sleeping policemen. Must be strictly a circuit car.

I think that there has been B30 conversions which have used twin rads, one each side of the front of the engine. Rads don't have to be conventionally shaped.
