why arent people using this manifold instead of the victor jr.
the performer rpm should make more power down low than the vic. jr. i would think

it just seems to me that it would be a better choice of an intake manifold for those of us not building an all out race engine

4th manifold down

 

Becuase it not available for fuel injected applications. No bungs for injectors.

 

neither is the vic. jr. you have to use a throttle body for fuel injected apps.

i just figured that the performer rpm has a better power range than the vic. jr.

 

You can get the Victor Jr with the fuel injector bungs already machined with fuel rails included, I don't think the RPM has the bungs machined, as far as the power band, they are rated for carb apps I believe, because of that when running fuel injection, you don't have to worry about fuel atomization issues at lower aiflow like you would with a carb, so that would move your powerband down a little lower for fuel injected apps.

 

so on a all motor 408 would running this set-up be better then keeping a lsx intake manifold ? what would be a downfall to doin this .

 

downfall=cost
benefit=not having worry baout pesky ole #7 cylinder and more hp up top
