Need a 'hook up'/help

This is for my daily driver. The motor is a motor I am going to be building on the side for the car. It will use a 3.5L block, top end will be T2 heads and reground cams, better springs, I could either use a stock intake manifold (i can post a pic later comparing the 3 possible stock ones). The tuning would be from a safc2 and a wideband (nothing else works on this damn car :frowning: ) The man purpose was to help get more air into the engine, boring the throttle body can only gain 3mm’s max, so using a different throttle body has to be done, but then the bottleneck on the stock intake manifold is restrictive so that needs to be made, thats why I thought of just going completely custom.

ok for some reason I can’t multiqoute.

But the design of the plenum can change I just was using it as a good reference because of the height, I don’t want it sticking out of the hood. Cost I think could be anywhere from 500-1300 for that intake manifold to be made, compare it with alot of other import intakes (minus 4 cylinders) its fair pricing.
