I have a volvo penta workshop manual for the 4 and 6 cylinder units (at 43 pages, not the biggest I've seen!)- if you need any specific information. Compr. ratio is 9.5:1 for the AQ105A, 115A,130A, 130C, but 8.4:1 for the AQ130B. "C" cam used for all models.
Carbs are either down-draught Solex 44 PAI (1 or 2 on 4 cylinder, 3 on the 6) or Stromberg 150 / 170 (again 2 or 3)

If anyone has a spare 3 carb horiz intake manifold (SU or Stromberg) as used on some of the AQ165A 6 cyl engines - I'd like it!

I've also got a supplement dated Dec 1973, which details changes to the block, crankshaft, pistons, conrods, exhaust valve seats (deleted), etc. Most seem to be improvements, but there are also some changes to metric bolts and some things won't fit the earlier engines.
Not sure how these correlate with the car engines.
