Made in Ohio USA and CAD modelled with extensive use of Computational Fluid Dynamics, the BE-LS7 & LS3 intake is the ultimate LS manifold for those who want the most HP from a single plane intake equipped LS7 - LS3 headed combination.

That's not a boast, but a dyno proven reality. During testing for the 2016 Engine Masters Competition, the School Of Automotive Machinists & Technology ran a test on their 367CI LS engine of our as cast BE LS7 intake against a CNC ported and hand finished Mast Motorsports LS7 intake from their 2014 Engine Master's engine.

The BE 4.0 LS as cast, made 50HP more on the peak numbers and 60HP more at Peak RPM using the Same Cam and Carburetor. Most importantly though, for those who might think this is a race only large plenum intake, the BE LS 4.0 outscored the MAST intake on the averages between 4500RPM and 7200RPM by a significant amount on a 6 liter engine !!!

The engine not only won the Nitrous class, but also took home Horsepower King and Torque Monster at the competition.

The manifold features near equal length runners that are shorter than existing single plane manifolds, allowing the potential for greater RPM and HP levels. Whilst the runners are shorter to begin with, we didn't want to make this a high HP only intake, so the cross section of the runners in its as cast form were kept to 4" in area at the plenum, so as to be useable in combinations around the 650HP mark, as witnessed by the School of Automotive Machinists testing. 

The manifolds are available for STD (9.240"), mid height (9.45"), and tall deck (9.750") blocks. The carb flange is designed for a 4500 carburetor, and the intake is available as a carbureted intake without fuel injection bosses machined, or a fuel injected intake with either 8 or 16 injectors. 

The carb flange has enough material to run a Braswell 7395 Carburetor with 2.4" throttle bores or an Accufab 8500 throttle body without any welding.
