I have a Victor W2 intake on my 340” engine. Intake is as cast, no porting. Would there be a benefit with getting it ported? I do not port myself so I would have to send it to get done.
Who would be the person or place to call?

Take your time and do a nice gasket match and blend into the manifold 2 inches. Radius the top of the plenum and run it. Do a neat job and you probably gained 80% of what a well ported manifold gets you.

This ^^^ or call Wilson manifolds and offer up one arm and two legs. Their porting is expensive but from all who’ve done it say it’s worth it.

What tools would I need? I’m 100% new to porting so I don’t have any tools that apply.
 
My intake is ported, however I changed more than just that before I made dyno pulls.

I will say this. IQ52 ported the intake. If he felt it was worth it, then it must make a difference. All of the changes I made yielded over 100hp and almost that in tq as well.
 
If you have never ported an intake don’t start leaning-experimenting on that one. What is the rest of the engine and car combination? What does it run now?

@roccodart440 what were the other changes that got you 100HP? Please complete the story.

Cam, heads, intake.
 
340” W2 heads. 600 lift solid cam, 11.4 compression, guzzles methanol, ran 9.90 without pushing it hard. I want to push it a bit harder after I get my license to run deeper in the 9’s. I was limited to 10.0 so I didn’t push it to hard.

My new setup won't work with the old gears and it is very unhappy with the convertor as well.

Buy the cheap a harbor freight electric grinder and a 25.00 router speed controller that they sell. If you want something a few dollars more get a foot speed controller from eBay like a sewing machine has. Slow and easy is the key. I will be posting up a few pictures of the Ford intakes I’m getting New Year’s Day. As far as burrs get don’t let anyone talk you into buying an aluminum single cut burr. Get a good three inch double cut and dip it in transmission fluid.

Thanks John for the link.


If you can’t find the other stuff let me know. The grinders run at 23000rpm and up so you gotta slow them down to control them. I love my set up but for the average guy costs to much if you aren’t going to use them often. I also look for deals on used stuff

I really like that swivel stand you have.
 
What would be the rough price to port an intake?
to buy all the tools, what would the investment be? I will probably only port this intake.

I probably wouldn’t do one for less than 300.00 anymore but used to charge less because most of the time I was porting their heads too. Here are some prices for the tools needed.
30.00 for the burr I posted above

Used all of that, it works.
You're absolutely right about just port matching and blending the flange to runners. Best return in time spent and it's hard to mess that up...well maybe not for some.
The approach is diff by some.
Leaned in or just straight and bull nosed, rough grit finish or just burr smooth.
I bolted a ootb strip dominator onto a j head that flowed 250cfm by itself...and it flowed 217cfm. People get caught up in head flow and never realize the intake needs work..and that they're essentially bolting on a cork that kills power .
The 340 vic ootb when bolted to 273 cfm heads dropped it to 245cfm... after the gasket match and flange/plenum blend ...264-266cfm. I ran an ld340 on my 410...never flowed it on the head..regretted that... but the heads are off and now I'm going to flow it bolted on and see how far off it was.
 
I contacted 3 companies that do lots of porting. To my surprise all 3 of them said porting an intake, ET will NOT change. They said maybe (a big maybe) up to 15 hp on an engine dyno but will help nothing on the drag strip. Prices were from $450-$900 to port an intake.

Isn't that funny how they tell you it won't do much and gives you bout 15 horsepower...then charge 450-900 for it.
Either they're doing it wrong or they dont like doing it eh

I was surprised to say the least. The one company actually told me they didn’t want to take my money and not see any gain at the drag strip. I was not expecting that.
 
That's like saying an intake manifold swap is worthless.
I think that doing one without it bolted to the head that will be used is somewhat a shot in the dark...but geez... just blending the plenum/flange 'just the slightest' can only help power

Possibly based n your combo ?
Another combo may have netted more gains .
