in an earlier post i got some suggestions on carbs ect..... but the intake is what im confused about, im planning to buy a holley 600cfm carb, does it matter what 4bl intake i buy. if so any suggestions? also i read a comment about the weiland stealth intake any opinions?
the stealth intake is a good intake. the edelbrock performer rpm intake is pretty much equal to the stealth. both of them work well on stock to pretty decently built motors. the airgap version of the edel. rpm intake is a good way to go.
There's another good intake too, Ford Racing's A321, also came in earlier versions under the Shelby "Cobra" highrise, Ford C9OX, & Edelbrock F4B. In addition to these, the old Edelbrock (twisted carb pad) Torker 289 was a good single plane for stock to mild builds. All these and the two listed above work from idle to 6500 rpms.
I suggested the Stealth 8020 because it is plenty mild enough for your stock engine. At the same time it is more aggressive than other "stock replacements" so it will give you room to grow when you do more mods to your engine. I don't agree that the Stealth and RPM are "equal" either. Upon experience, I found the RPM to be overrated as an aggressive intake. I shelled out for a new RPM once, and then dumped it quick after running it. Also, from experience, the Stealth is a very high quality piece. Don't mess around with the generic and unknown brands. There are pictures on this site showing the terrible quality that you get for only a little bit of money saved buying those cheaper copies. Good luck Dave
thanks thanks everybody, ill probably end up buying the stealth it does seem to a better quality intake in my opinion :Handshake and it has better reviews
I was going off a magazine dyno shoot out between several of the common dual planes and a single plane Victor on a ford small block. At street RPMs, that is up to about 62-6300 on a 331 or 347 (Cant remember) the Air gap flat out won through most of the power band. I have run the old twisted torquer and it was good but the power increase when I switched to the RPM air gap was very noticable. The car pulled harder all the way to 6400 where I shift. I can't remember if the stealth was in there but I'll still bet on the Air gap. I'm sure it would be hard to tell the difference in seat of the pants feel though. The reason I felt so much was due to the drastic difference between the dinosaur single plane and the new "high tech" Air Gap.
Just food for thought, magazine dyno tests are generally paid for by the intake manufacturer and rearly any tests are truly fair or unbiased.
Oh yeah the stealth is a good intake for the money. If you arent going to "grow" down the road, edelbrock performer will work fine and you can find them around used, cheap.
On a stock motor, and on a moderately built motor, I find that the mild single plane Torker289 (not TorkerII) is a very nice manifold. Quick revs, good for up to 6500, but also decent down around 2500 rpm. On my stock motor, when I swapped from a Performer289 (basically Edelbrock's aluminum replacement for the stock iron manifold) to the Torker289, before I even drove it, just gunning it by hitting the throttle under the hood, I could tell a big difference in how fast it revved. Seat of pants "felt" like a good 20 hp. Room to grow, too, and I used it on my stock motor through GT40P heads and headers, and then on my current .040 over roller block. I know, no numbers or data to prove anything here, and just seat of pants. Just throwing out alternative suggestions and stating that it doesn't HAVE to be dual-plane to be street-able. And cheap. Find them on e-Bay for $100-150 from time to time.
There used to be a dyno comparision on the net, of the RPM's, Stealth, A321, F4B, (all the high rise dual planes) and all were in a 5-10HP range between em. These are 20 hp above the stock iron(60's era) aluminum (early 80's) and the Performer & Action Plus. Don't recall where the Torker289 fell, but it should be right with the high rise dual planes. The Vic Jr, Victor and the Funnel Web single planes are generally only good above 3000- 4000 rpms with a 289/302
I do remember the test had a Funnel web single plane in it too. Might have been different issues. The Air Gap and the other newer dual planes beat all the single planes including the Funnel Web in the below 6000 RPM area. The Victor was just shy and rarely ahead by a few HP untill the mid 6000s then the Funnel Web pulled out to a 20 or so HP lead by the 7000s. One test was on a 427W stroker. The conclusion was something like why would you ever want a single plane on a street car there was no advantage even on long stroke big displacement motors, and it actually hurt performance and gas mileage. The extra torque (45 LB/FT in the lower) produced throughout most of the power band was worth it.
I've tried several intakes and always go back to the Torker 289 myself. It's very true about Edelbrock buying off magazines/car programs with hefty advertising budgets! I took my Torker 289 off one time to put on a new RPM. The RPM killed my performance after 2500 rpm and didn't gain a drop of torque on the bottom! I couldn't get the RPM back off fast enough. So don't give me this "single planes are worthless" crap. My neighbor got a Stealth and a 770 Holley vacuum for his HEAVY pickup. He enlisted me to install and test it out. We took off an RPM and Edel-junk 500. That truck hauls buttocks now! Heavy as it is with a little 302. Any magazine or television show on the subject would swear the thing was over-intaked and over-carbbed for the stock little engine and heavy vehicle... Anything that goes against advertising money is bad. Vic doesn't make any money when you buy a used Torker 289!
I will give up my Torker289 ONLY for a 6-71 Blower manifold... I have actually owned TWO used Torker289s. I sold one to Bowstick, and told him if he didn't like it, I would give him his money back to have it back. Just in case, I would like to keep a second one around.
