I painfully struggled with the aluminum blocks that Paul designed for the
P-port tubes. Buying the drill bit for the top, the fuel log rail, drilling
them to match, then trying to get them to mate / lock down without spilling
fuel everywhere. (Plus the welders hourly rate). Spent easily over $600 :(

My next intake will definitely use something like billet speed. Let me know
how it goes.

I know nothing about this, but do you want the injectors at the start of
the intake runners, to give it a long time to mix with the air? Since we
aren't looking for quick acceleration (injectors closer to combustion) and
more long term cruising MPG benefits.
