Product Description

Fits 1986 and before  Mercruiser GM V8
-3 inch elbow 
-3 inch spacer

In the V8 GM Small Block, GLM's fully tuned 
design guides exhaust gases directly to 
the riser without turbulance and back pressure.
This increases the engine's performance by 10%.
These GLM manifolds also feature an additional 40%
increase in water cooling area that decreases the 
manifold's overall body temperature significantly.

*All manifolds and risers are powdercoated black for maximum corrosion protection*

**Cast Iron manifolds and risers come with a 2 year warranty**
