Aftermarket intakes fit the Chevy inline 6 230-250-292 engines

Just interesting for the 6cylinder hot rod guys.

I see they are made to be used with the PES Lump Ports.
Where would that intake place a 4Bbl [and air cleaner] in relation to a power brake booster?

Most probably don't have power brakes because of cam. They are good looking manifolds and perform well like the AussieSpeed ones. I thought about using one when I was doing the 6 on my 81, but they are pretty pricey according to my budget.

I'm running a Crane Cam 260H on my '68 C/10 Stepside -- not especially lumpy, but not stock. At operating temp [180*], 40 PSI Oil Pressure, 700 RPM idle, my Vacuum reads 17.5" Hg. I have stock manual brakes -- same 2'' drums all-around -- and it stops fine when they're in good order.
But if I were building another L25 for a bigger, heavier bodied rig like a 4WD '67 Suburban, I might want power brakes.* Also upgrading the front Dana 44 for a '71-'72 D44 would give me the options of Power Disc Brakes and Power Steering. If it had P/S, Hydroboost might be the option.
*The '67 K/10's stock vintage brakes sucked. [DANGER -- SELECT ALTERNATE TARGET]
If one is contemplating a HiPerf 292 build with Lump Port head work, the budget is already astronomical. Like NASA.
