Intake Manifolds HELP!
As many of you know I am nearing the assembly (FINALLY!) of the big block. I am currently concerned with my intake manifold of choice. I will be using an Edelbrock Torker II intake.
My first question is, how much horsepower am I "leaving on the table" with this intake? I was told that I am loosing about 50 horsepower by going with the Torker II. Is there a better intake manifold to go with? I chose the Torker II mostly because I was under the impression that it would fit under my stock hood, but if I'm loosing 50 horsepower by going with it I'll change intakes and get an L88 hood. I'm NOT looking for more torque, I want some horsepower.
I'm currently gasket matching the Torker II intake, is this a waste of time or time well-spent? The heads are gasket matched so it only makes sense to me to gasket match the intake too. Opinions?
Thanks :D

Bence, typically you can expect 5 horse or so on a match porting job. Super high flow engines may experience an even higher jump. I'm in the same ball park with my Victor Jr. I have alot of grinding to do:

Re: Intake Manifolds HELP! (Stingy74)
what compression ratio are you going to have? I had a Torker intake and the ports are way to small. even the Performer RPM has ports bigger then the torker. i would use the air gap if it would fit, if not, then the regular RPM. if you are really looking for power go for the Victor JR (providing your heads flow well).

Re: Intake Manifolds HELP! (bence13_33)
Shane,
I am glad you are rethinking this. I had doubts about that choice in the past.:confused: I agree if you can fit the RPM or RPM Air gap (both are same height) you would be far better off. They will provide great flow from 1500 - 6500. I don't remember your rev requirements but surely you aren't going much higher than that are you?
I was able to get the RPM Air Gap fit under my SB hood , but a big block is a different story. I can't answer that question, but it might under your hood. What hood do you currently have?
If you are going for a higher revving engine the Victor Jr would be good. But with it you will lose some on the low end.
The Torker II has a little of the worst of both worlds. The low end is only OK and the high end may flow better than some dual planes but its not a Victor Jr.
Just remember, its never too late. :D good for you... :yesnod:

Hey bence,
That Performer RPM (both the standard and Air Gap) won't fit with the stock hood.
Here is a link to the Edelbrock site. Click on "Intake manifold" and then "Big Block Chevrolet", scroll down and you will see the info on the manifolds.

I think you would be making the right choice to go with the Performer RPM and besides, that L-88 hood looks awesome on our cars!! :yesnod:

How did you determine 50hp? Have you read this yet? http://www.72chevelle.com/lashword.htm BEWARE, it will make you want a roller!
As far as manifolds are concerned, you don't have any better choices :( The dual planes above will never fit under the stock hood. I also had a Weiand 7513 (www.holley.com), and it was nicer/taller than the Torker, but not by much. It might fit with the right air cleaner combo.
If you want to put the Tremec off for a while and spend that money on fuel injection, I can tell you how to put an Edelbrock Victor Jr. under the stock hood for the ultimate sleeper... (my manifold is being converted this week!)

Joe:
One of the forum members told me about 50HP loss because of the Torker II (I found that hard to believe, but thought I would ask you guys). As far as fuel injection goes :nonod: :nonod: :nonod: . First and foremost the price (enough said ;) ). Second of all I don't like....no I hate fuel injection! Too many wires, computers, injectors and what not :D . I love the simplicity of the carburetor, furthermore (IMO) there is nothing like the sound of a high compression, solid lifter cam'ed, carbureted engine :yesnod:.
I think I'm going to stick with the Torker II for now. The ports are small, but I am gasket matching it so it should flow a little better. Now if only I had a die grinder, porting this intake would be soooo much easier. I've spent the last two days or so grinding away at the intake....2 ports down 6 more to go *sigh*. If I were to get a taller intake I think I would go with the Holley Strip Dominator. My buddy Tim Dotts ran this on his 454 Camaro and swore by it.

The problem with the Torker is the height, not the size of the ports :( The floor is flat, so the air has to make a hard 90* turn, and that kills flow. Talk to mountainmotor, he's modified a few Torkers to work better.
What are you porting it with? You can get a few 6" carbides for your electric drill from Summit that will cut right through that aluminum.

Re: Intake Manifolds HELP! (Flareside)
hey bence. I'm doing the same with my torker II on my SBC....didn't start working on it yet since I'm more focused on prepping the block. But its on my schedule. I thought a lot about it and I think if you port match the torker and maybe add some material at the base (so its not flat), it would end up being a nice intake....just my opinion tho. Anyway...I don't think you'll lose 50hp just because of that.

Re: Intake Manifolds HELP! (bence13_33)
You could get a taller intake & a L-88 hood & the hood painted to match the car & the car painted to match the hood, etc...
