Iron Eagle GEN VII
The GM 8.1 liter big block was used in numerous marine and truck applications. Up until now, there have been very limited options for upgrading its performance potential.
Dart has developed a whole new world of performance for the metric 8.1/8.8 liter style big block engine. New Cast Iron cylinder heads with improved high flowing port designs and efficient combustion chambers greatly enhance power and torque output.
Dart’s Cast Iron cylinder heads for the Gen VII 8.1/8.8 liter style engines offer improved ports and chambers as well as added valve train versatility.
We have introduced the only carburetor style intake manifold for these engines currently available. This dual plane Cast Aluminum unit offers new performance possibilities.
