where does this vacume hose go
 

ive got a 94 gt with a cobra ford racing upper and lower intake. there are 2 hoses coming out of the center on the underside and one from the back left corner. when my friend and i tore the engine down when we put the hoses back on we were pretty sure they were in the right spot and the car ran good. i just wanted to double check since im replacing the header gasket right now and the intake's already off

so what are the hoses for and where do they go?

btw, there was a little bit of a surging issue at idle which could either be because ive got an x cam and my computer hates it and the motor's stroked to a 347 (yes i know i could make more power with a better cam but im on a budget and it was free-ish) or because the vacume lines were hooked up wrong. or maybe i need a vacume canister

By "back left corner" i think you mean right next to the brake master cylinder? If so, that hose goes to a "manifold" or little rail on the driver side fender to supply vacuum to numerous other vacuum lines. Another hose goes to the PCV valve ~3/8" and the final one a small 1/8" or 1/4" line goes under the heater hoses to a solenoid on the passenger side. The solenoid (as I'm calling it) has an electrical connection, a rubber sleave and two barbs on the bottom for vacuum hoses.

It's running like crap because of the cam. Have you hooked a vacuum gauge up to see what kind of vacuum you're pulling?

u got the intake off to do a header gasket?

50nut i think ive seen your car on youtube before.. you got a burnout video on there?

thanks 50nut, ill make sure everythings hooked up right

92 - its not running like crap, just surging a little. thats a good idea though, ill have to go find one

and i took the intake off because i had an extra intake gasket incase i broke it. also wanted to check the tubes to make sure they wernt worn. plus i just like as much room as i can get
