Here is the Chevrolet big block V8 engine set up with 2 four-barrel Holleys on a tunnel-ram intake. Serious street motor with GM’s symmetrical intake-port heads, Dart valve covers and nice exhaust headers. Detailed 3d model with many parts, but no internal pieces. Dimensionally correct within reason, but not an exact reproduction.
Someone will say that Tunnel Ram is a pure racing intake manifold and is not suitable for a street engine, but this is not so and it all depends on the configuration of the intake manifold, various tests also confirm that with the proper configuration, this intake manifold gives an increase all range.
