For this discussion lets talk N/A.

Does the Pontiac community need a better head casting or better intake manifolds for the head castings we have?

Lets say that you have just spent $$$$$ getting a set of zxqwz castings or billets ported, and that they now flow record numbers. That by itself is meaningless, since the running engine only knows / sees what the total intake track flows.

So what have you seen different intake manifolds flow and how much modification was needed.

How many have spent as much on their intake manifold as their heads?

Many more serious buyers spending money. The rest will follow.

Any Intake that is built takes away work from Marcella who builds OUTSTANDING Intakes of all types and sizes.

So my question is are you asking for a Upgrade over say a Larry W dual quad Gutsram intake from someone like Edelbrock, etc.
Butler tried that deal with a supplier that fabricated a aluminum plate T-Ram intake and Butler barely got his money back.

So where is the bang for the Buck, Brian? More info please.

CNC-ported intakes?

I'm applaaed at the air flow interrupts in the whole lineup. We need:

Cold air fed - Big air filter box with velocity balanced volumes and underhood managed air tube.
then i get frustrated at the carb flange, as if it needed turned 90 forward (like a mono throttle body). now i can think about intakes.

More intakes. The more I learn the more realize just how much there is to to a really good intake. You can have more money with a intake manifold and its port work than the head porting. Mike L told me he had 4000-4500 worth of work done to his BOP. I would think it was more than the port work in the heads.
Going to have a nice intake done. Thing about spending real money on a great intake. You will always have it, it does not wear out. The good work just does its job without risk. I can have the Tiger made to work with big E heads, and it will work with High Ports and the Super Wedge heads with a little effort. How much plenum work do I get done if any ? That will be up to John and what he thinks I could use. Best bang for the buck for what I am doing.
From what I understand, all the big dogs with the bad @$$ high flowing heads have a intake to match. Can not have a head that flows 450cfm if the intake holds it back. It seems the BOP just port matched and bolted on will beat a highly ported Victor. But even it needs some plenum work to really rock.

More CV1 heads

But, I think any really high flowing heads combination will likely go with a fabricated sheet metal manifold. I'm pretty sure Mike L said his next step was to go to one from John Marcella. Said his ported heavily modified BOP was holding his combination back. Then again, if you wanting to run in some weight/ci classes, a fabricated intake will get you an additional weight penalty. Guess it somewhat depends what type of racing.

False, not a true statement

So.. slowbird, what did you find out ? You are one of the guys I was referring to. You had one of the Victors cut in half and had the he!! ported out of it and re welded back together. Dan Barton intake. And.. why you running the BOP right now. You did say in a old post that you picked up just putting one on. Enlighten us.
Maybe Kinsler can chime in on this. I believe he started out with a heavily ported Victor and now also runs a BOP. Interested in what he found out.

I am going with a Tiger simply because Mike told me he liked it and wished he used it from the start than the BOP. But, I know John likes the modified BOP and the Tiger as cast. Either way I am going to end up with a hell of a intake.
Mike told me a Victor would choke his heads. So it would choke Lil Jacks old heads I now have ,dont you think ?

A maxxed out engine combo would have a fabricated intake, with exactly the correct length runner to match the cube, cam and desired rpm. Plenum volume would be tuned to get best perf on the track, not highest number on the dyno. Straight but tapered runners of equal length would be a tunnel ram and 2carbs.

Good basic summary!
I don't get why so many are hung on single four, especially when most are not racing a class requiring it.
Still plenty of reluctance on efi as well....carbs a tid more power but not as consistent.

That would kind of be impossible.

[steve25]

A splittable Intake !

John,
Understandable since you started with a lump of cast Aluminum. How many people here have at least 33% of the cost of your motor in their motor?

Steve,
If the available intake manifolds were make splittable. How many of them were still not have enough metal in some places for the larger ported heads?

[Tiger Paw]

John L, if a person were to do there own engine program, they might need to get several fabricated intakes in order to max a combo. So, a lot of money is spent. Most guys buy engines already science or crate type from high end builders.

I don't run a BOP intake (never have), i did test one against my victor and the victor stayed on the engine for a reason and the BOP was sold.

The dyno doesn't tell the full story....that's why we don't race dyno's.
