Post new parts lack emissions equipment

Hi guys,
my Camaro isn't dead!!! Hoorah!
Which leads to my questions about emmisions eqpt, and wether it will have a derogatory effect on the running of my engine to get rid of some of it.

It's a 78 Camaro, and I'm planning on getting a comp cams xtreme energy 262H K-Kit, edelbrock performer airgap intake and either a holley or edelbrock carb...

thing is, the intake has no provision for EGR, and the carb has only one provision for either power assist eqpt OR PCV, meaing I'll have to not have PCV if I want to run my powersteering and power assisted brakes!

I don't need to keep the emissions stuff to pass an emissions test as in the UK we don't need to on a car of this age (which also means I'll be removing the stock CAT and putting on dual exhausts with just mufflers).

However, other than just bolting on the parts mentioned, do I need to do anything else to keep my engine running healthy? e.g. would I be better off/ do I need to try to keep the PCV stuff?

You need the PCV without it you'll have excesive crankcse presure and poor ring seal.On my engine I just ran a hose out from the vac.port on the carb then T'ed it off to the brake booster and PCV.You'll also need a fresh air return(stock its that the tube that goes from the aircleaner to the valve cover)all ya need is an open air breather like them crome moroso deals.
As far as EGR and smog pump(if equiped)and charcoal canister none of it is nessasary to make the motor run and without it more than likely you'll see minor gains in power due to freeing up power.

As monte said, I wouldn't worry about the EGR junk. Most aftermarket performance carbs/manifolds are set up to not need EGRs. I would second the idea to keep the PCV valve. Either T-off the vacuum line or drill out the intake and install a vacuum fitting in the intake for the brake booster.

Hi Andybird,
Definately use a tru roller cam chain, and a set of small tube headers would go well with that combo. Of course you will curse me royally when you start installing them.

I'm lost.

This is an air gap for your car. As you can see, right behind the carburetor mount there is a large hole directly to an intake runner you are going to have to plug. Usually one uses a fitting that will attach to a hose for the power brakes. That way you can hook the Positive Crankcase Ventilation device to the correct port on the carb. You do need to keep this system functional. It costs no power and actually helps keep the engine bay and underside of the car cleaner.

I absolutely do not understand why any of this will affect the power steering.
