So I got my 350 S10 up and running (well kinda but it has fired and moved under its own power)

I am putting together some twin turbo headers for my build but the factory vortec spider fuel injection is not going to meet my goals (IE more than stock)

I have been looking at the EFI intake options and am leaning towards the Super Victor EFI with either a plate for the stock truck TB or an elbow for an LS1 TB (have both TB's handy) my only gripe is the victor has NO provisions for any vac ports (for things like power brakes and my MAP sensor, etc) I am guessing the casting is not thick enough to drill and tap so a boss will be needed?

I like the proflo XT also but I am concerned about TB clearance with my factory accessories (I am running AC on this truck) The same thing comes up with the Weiand/Holley Stealth Ram intake....will they clear?

also will the super victor give up too much bottom end? I know I will loose some over the factory intake but this is also a V8 s10 so not like it is short on power to weight.

I have a remote areomotive regulator laying around and some AN fittings to plumb it all up with.

The sides of the plenum should be easily thick enough to drill and tap for sensors. Your S10 is light enough that a single plane will be excellent. Any more lowend and you will have extreme traction issue, eh?

If you have the truck type serp brackets the pro-flo xt will not work nor any other front TB manifold like TPI. You'll have to swap to the passenger car brackets for clearance.

I have a 91 K5 Jimmy with the TBI 350 and set a TPI on it and found no way to make it work without swapping the brackets.
