It offers the airflow of more expensive heads, at a much lower cost. It does, however, require a specific intake manifold (the L31 has four bolts per head attaching the intake manifold, as opposed to the "traditional" six bolts per head found on older Chevrolet small-blocks). Chevrolet's L31 was replaced by GM's LS-based 5.3L LM7 and 6.0L LQ4.
LS1-b - (23 built of LS1-0. LS1-a, and LS1-b together) LS1-c - (198 built of LS1-c and LS1-d together) LS1-d - was the first to have water ballast, following a class rule change. (198 built of LS1-c and LS1-d together) LS1-e - version was built privately by a Rolladen-Schneider employee under the direction of Wolf Lemke. Differs from the LS1-c ...
The LS7 was developed as the successor to the LS4, one of the most successful gliders ever produced.. In a departure from the design philosophy of the LS4, Rolladen-Schneider set out to design the LS7 as an uncompromised competition machine, seeking the highest performance possible with the technology of the time.
The design of the LS4 was influenced mainly by the experience Rolladen-Schneider had gained with the LS2 and LS3 flapped gliders. Wolf Lemke returned to a double-tapered wing planform, giving it a larger area comparatively to the LS1 and LS2, and enlarged all control surfaces: the ailerons were elongated and brought further inboard and the tailplane span was increased.
In 2006 World Gliding Championships at Eskilstulna, Sweden, LS8 took the first and third places. LS8 was the winner of 2002, 2004, 2005, and 2007 European Gliding Championship. Many regard it as the best all-round standard class glider.
The traditional five-bolt pentagonal cylinder head pattern was replaced with a square four-bolt design (much like the 1964–1990 Oldsmobile V8), and the pistons are of the flat-topped variety (in the LS1, LS2, LS3, LS6, LS7, LQ9, and L33), while all other variants, including the new LS9 and LQ4 truck engine, received a dished version of the GM ...
A stripped down FLH touring model with an updated Duo-Glide style headlamp nacelle that replaced Electra Glide Sport. 1994–1998 used the 82 cu in (1,340 cc) Evolution engine power plant and older frame dimension (seat height), with fuel injection being offered as an option from 1996. The 1999–2008 used the newer Twin Cam engine and had a ...
The main advantage of the reverse-flow cylinder head is that both the entering inlet charge and the exiting exhaust gas cause a tendency to swirl in the same direction in the combustion chamber. [1] In a crossflow head the inlet and exhaust gases promote swirl in opposite directions so that during overlap the swirl changes directions.
