1969 142
Chapter 2
Updates on the 142: we managed to find a proper set of 45ADDHE Solex carburetors and the correct softmounts for the fuel supply end of things. We also came up with a genuine VCS [Volvo Competition Service] head, which led us to build a new, more correct, engine for the car. We weren't aware of the condition of these parts until we'd already committed to the engine build.
In addition to the carbs mentioned, this VCS head calls for an R cam, steel timing gears, header and high volume fuel pump. To go along with these performance improvements - and deviating from the original specs, we assembled the engine using I beam rods, forged pistons, a lightweight chromoly flywheel plus a few other minor things.
Unfortunately, one of the softmounts is dried out and cracked, so we can't make use of those until we come up with a replacement (got one? let us know!). Further, one of the carbs has been broken and welded back together. This kind of repair is fine, unless the result is that the inside of the carb isn't round and the throttle plates won't close. The end result is that we're not able to run the VCS inspired engine with the correct VCS intake parts quite yet - we'll get those pieces corrected and someday the customer will have a more correct end result.
Until then, it's running like a champ on the tried and true 45DCOE Weber carbs. These particular carbs were originally used on a Lamborghini Countach, which seems like it ought to make them even more awesome than a 'normal' set of DCOEs.

The specimen: an unrestored beauty. Lamps are Swedish manufactured Bosch Knick 180s.
The new engine comes together.
Intake system issues: the softmount shown in the first picture is cracked and results in a substantial vacuum leak. The second picture shows a good one.
Welding repairs to the lower mounts, shown, distorted both carb throats and left the throats with pores and irregularities.

Header fitment. This is the simplest thing to address and we managed to get it resolved in house. As soon as the original header was corrected, it was delivered to a master fabricator who is making a duplicate.
Current and temporary setup.

Chapter 1
Once a standard issue 142, this sample has been fitted with a variety of GT components as offered by Volvo Competition Service. Much of the modifications took place before the car came to us - we rebuilt the engine to E specs, including a D grind cam, Melling oil pump, steel timing gears, NOS +.030" Mahle pistons, rebuilt E head with hardened seats and new valves.
Initially, the car ran with a pair of SU HS6 carbs that had been rebuilt to an excellent standard by our friends at Island Automotion; and ignition was provided by a Bosch 007 distributor that would typically be found on a 1974 B20F. Now the engine sports a full Volvo Competition Service intake setup - proper intake manifolds, Solex carbs and correct air filter assembly. Ignition has been upgraded to a 123 ignition distributor with the 1971 E curve in use.
