My new 468 is as follows: 290 GM heads(2.19/1.88), 9.8:1 comp., comp magnum 286 flat tappet hyd., 2" headers and holley 850 DP. I can get a weiand oval port single plane intake for nothing from a friend. Would it work well with this set up? ( car has a th350, 2800 stall and 3:42 posi also) Thanks!

Which one? Normally I would recommend a dual plane but free is always good.

It also depends on the main intended use...for the street a duel plane is normally a better choice then a single plane BUT for the strip depending on setup the single plane is a better choice...So what is your main intended use?...Of course free is always good and many people, myself included, have ran single plane intakes on the street...for me it was a Vic Jr.

Car is strictly a street cruiser. The intake seems to be low profile (short runners?) and with oval port heads I was thinking it would be OK on the bottom end ( cam works from 2200 to 6200 rpms- per comp cams). The weiand # is 7514.

I would bolt on a RPM Air-Gap. The Air-Gap is hard to beat on the street! :thumbsup:

free dont cost anything ,i would use it and maybe put a four hole spacer on it if you have enough clearance.

 

[Motorhead62]

Free is good, only costs a set of gaskets!

I'm gonna give it a try. If the low end seems a little soggy I can always swap to a dual plane.

Years ago, I put an Edlebrock Tarantula (TM2-O?), a similar "single plain" intake, on a stock SS 396 Chevelle w/ 4 speed and stock gears that I owned at the time. I lost an awful lot of bottom end. Later, I installed that same intake on an SS 396 Nova w/ 4 speed and "4:88" gears and found it was a totally different animal! The gears made a big difference in the way the intake responded and in the "seat of the pants feel!"

I think for a street car, I would be more inclined to stay with a good "dual plain" intake.

Gears do have a lot to do with how much you will suffer on the bottom end, But i would suggest a rpm air gap, your setup seems relivly mild and the cam is a low rpm cam, But what is prob going to save you is your 2800 rpm converter, Your prob going to get a little bit more than 2800 out of it because of the gears and all the torque your motor will make. Im kinda on the fence.

Trantula intakes looked cool but i was under the impression they had horrible flow charicteristics. But like i said they looked cool, the only intake i know of there the carb is kicked out at a 15* angle

The Tarantula is 30+ year old technology. I used it as an example and not a recommendation. There are much better manifolds available "today."

"My point" was that a "single plain" manifold would not necessarily be a good choice for a "street car." A good "dual plain," such as the RPM, would be a good example as well as many others.

By the way, that same Nova with the Tarantula and it's "bad flow characteristics" was never beat.

I was just trying to say that comparing a tarantula to an late model after market single plane isint exactly apples to apples.
