No standard carb model produced more than 155 ponies, and most well below that. The power didn't get hiked beyond 155 until the arrival of fuel injection. It was never as quick as rose tinted legend would have us think, and the more humble 3.0 Ford Essex unit produced more power and, in most applications, faster cars. The engine in this one appears to be P6 im origin, so would gave started life with not a lot of power. Clearly the original carbs have gone (the sticker indicates Holley carbs, but who really knows?) and its not a difficult job to uprate the camshaft, but it began its life as a fairly humble unit. They're not that torquey for their capacity, and don't even sound very nice compared to big bore V8's. Aside from in the 70's when there wasn't much else about, there isn't really a great deal to recommend the Rover V8 other than its relatively modest weight,

Also ignition timing varied a lot over the years, getting it wrong would also have a huge effect on power and economy. All carb versions of the V8 were rated at 155bhp, even on the horrible Strombergs with the even more horrible FASD on them. The 136bhp rating was in fact for the straight six 2600 models, essentially a revised Triumph 2500 engine with a Dolomite style head designed by Triumph engineers sat on top of it and "that" problem with the oil restrictor valve that caused the camshaft to temporarily sieze in its bearings. You're right about the advent of EFi hiking the power, it went up to 190bhp and the injection system was a Lucas version of the Bosch L-Jetronic system. However some head and cam work had also been done to take advantage of the EFi so even adding a pair of Vitesse heads to a carb model would give a boost of 15-20bhp. As for the Essex 3.0 V6, no they didn't produce more power Even Ford only rated them at 138bhp (after some mods 2-3 years into production prior to which they were only ~130bhp) and a 38DGAS doesn't have the flow capabilities of a pair of SU HS6s or HIF44s - two 1.5" barrels of the 38DGAS Vs two 1.75" barrels of the SUs - big difference! Also the Capris/Granadas were lighter than the SD1 but the SD1 V8 would leave and 3.0 V6 Ford in a cloud of exhaust and the Ford would never get near catching up. Even when Ford changed to the Cologne V6 and fitted K-Jetronic injection to the 2.8 which boosted power from 135bhp on the Solex carb to 160bhp with injection, they still weren't that quick. Never came across a 2.8i (Capri or Granada) that an SD1 V8 wouldn't leave behind, assuming both cars were standard. In short, the Rover V8 was a lot better than you're giving it credit for but the big point is that these days, it's outdated at ~60 years old. Technology has moved on and we now have 32v V8s such as the 1UZ that can also return surprisingly good fuel economy. A friend bought the later 1UZ which was a 4.3 with VVTi and that happily returned 36+mpg on a run. At nearly twice the weight of a Capri it was not only quicker but more economical. Fitting something like that into a Volvo would be the way to go if you wanted a V8 Volvo unless of course it's an S80 or XC70/90 in which case the Yamaha 4.4 V8 which Volvo themselves fitted. That said you could just buy one ready made..................

Wherever the engine is mounted (forwards or backwards of the original redblock) the sump is likely to need modifying to fit but given it's ighter than the redblock having the gearbox a bit further forward is likely to help balance the weight distribution. I wonder if the buyer got there and found it had all been bodged and walked away?

Personally I can't see the point of this type of modification - is it really going to make a better motor car than the Lexus the motor came out of? Alan

https://www.ebay.co.uk/itm/115126550...53.m1438.l2649 At this rate it should reach its value (about £999) by Xmas 2022: :-) PS. This motor car will become an historic vehicle on 1 April 2023 - its value will increase then, perhaps to £1,500 - and it will not need a MoT test (now that is a scary thought, it was last tested in 2009!).
