Are there any 3800 Series 2 cylinder heads?
We have now studied and flow-bench tested more than a dozen different 3800 Series II head porting designs, and are convinced our Stage 2 heads will outperform any other heads on the market retaining stock valves. These 3800 Series II cylinder heads are now available for both L36 and L67 engines.
What’s the difference between the 3800 and 3800 Series engines?
Although the stroke for the 3.8 L engine remained at 3.4 in (86 mm), and the bore remained at 3.8 in (97 mm), the engine architecture was vastly changed. The piston connecting rods were 1 in (25 mm) shorter, so the crankshaft was redesigned. A new intake manifold improved breathing, and a new cylinder head had larger valves.
When did the 3800 Series 3 come out?
In 2005, it was the first gasoline engine in the industry to attain SULEV (Super Ultra Low Emissions Vehicle). Also note that Series III engines are the base for any 3800 produced for the 2004 year and up. This means the same block, heads, & connecting rods apply to any remaining Series II engines made after 2004 also.
What kind of cylinder heads do I need for a L36 engine?
These 3800 Series II cylinder heads are now available for both L36 and L67 engines.
