Before you all crucify me, yes I have searched all threads..

I'm wanting to know if a fuel injected N/A 13b semi pp is worth it for a good power gain.
I am not interested in adding a turbo and a full PP seems
​​​​too wild for street use.

Cheers

They make no more power than a large bridge based on my experience and dyno numbers and realistically cost as much or more than a full peripheral port to machine and build out. Modern EFI also makes peripheral ports far easier to drive and you have options with regards to port overlap for reasonable street driving while also netting the benefit of a full periph.

I street drive a peripheral port and while rowdy, it's very drivable. An NA Semi-PP would make no where near the power of a full PP.
