Thanks in advanced everyone if you leave a post or comment!

 

Not sure exactly what you're after. You said a lot but left out a bunch of important information.

Okay.

Which one?
Never heard glowing things about Edelbrock cams.
Stock "what" heads?
Which ones?
Basically a waste of money.
Which ones?
Not enough intake for the cam (if you stick with the one above).
No love for vacuum secondary carbs here.
Which ones?
What exactly?
Which one? If you have an in-tank electric pump, it needs to be a return-type regulator. If you have a mechanical fuel pump, you don't need the fuel pressure regulator (if you removed the in-tank electric pump).

 

Damn, lol um it's a forged crank, the factory tpi heads, plan on swapping the carb/intake with the matching one that goes with the package and I've heard good things about the cam I have, new walbro in tank pump and it is a return type regulator, need to find the info on the cam but they match the cam and are beehive or and I forgot scorpion roller rockers 1.5 ratio the blue ones

And I'm basically looking for a decent all around performer, handling more say power in the high 12 low 13 second range
Honestly car runs great as is not really looking for motor mods input I love how it performs, I should've stated that originally!

 

anyone?

 

I agree. I would try another intake, like an RPM air-gap, and a mechanical carb.
You might want to get yourself a wideband O2 and work on the tuning.

 

Does the rpm-gap come available for centerbolt heads?

 

Still need an answer for that question....also do you think that an Edelbrock RPM AIR GAP Manifold will fit my combination good?

 

Yes they fit.

That's not the edelbrock part...Who makes that one?

 

Like most of our automotive parts, the Chinese make them.
There are many different knock-offs out there from the same source, but with different names/labels.
You can save a lot of money over the Edelbrock part.
It's true that some have blems and small imperfections in the castings, but that's also true of the Edelbrock or Dart parts.
There are many options out there to choose from. The one I posted has the adapters for your middle bolts.
Most of them out there at least have the bolt-holes already slotted.

The air-gap design gives up a lot of heat in the intake manifold, and has no EGR provision. In many cases this means more fine-tuning for everyday street use. It's less forgiving of a bad tune. The payoff is more WOT power via cooler charge, and due to the design of the ports. You lose some hood clearance with this design of intake.

 

The ebay ad says "Elite Series", so basically it's a generic from China.
Like I said, there are many out there.

 

Will it fit under my stock hood?
How much is it? My computer won't let me view the page right now...did earlier.
I know the edelbrock part isnt too much and it is american made.

 

Yes the intake will fit. As for your carb and air-cleaner, you will have to figure that out yourself.

The link says $154
but there are always others for sale out there. You might find one for $50 on craigslist.

It doesn't sound like you put this engine together yourself, so it might be best for you to consult directly with the builder, or the person you plan to have do the work.

 

Wow, lol um how do you figure that I didn't build it? Lol You right but me asking bout stock hood clearance doesn't mean anything
I am perfectly able to tune and mod my car
Thank you for the consideration though. Appreciate the help sir
