Intake Recommendation for 468 Olds

I'm finally buliding another 455 Olds for my pickup. The truck will be for weekends & cruises. These are the eng specs:

.060 over to 468
10.25:1 comp
230* hyd cam w/112 LS
3.54 rear & 29" tire
Ported Edelbrock heads w/300 cc intakes
1.875" headers & 3" exhaust

A CPT 200r4 ultimate trans w/matching converter will be bolted to it.

I'm looking at these 2 intakes: Edelbrock Performer dual plane, & an Edelbrock Torker single plane.

I haven't decided on a carb yet (that will be another thread) It will be a modified Q-Jet or Holley.

I was initially gonna go with the Performer, but a single plane might work with the combo too.

Thx

I'd be using one of THESE. AFAIK, Edel. doesn't make an RPM for the Olds 455 yet.

Shop around on the price- I just hit PAW because they came up first.

Are you using or ever used that brand? I saw one of those a few weeks ago at Pomona, it was rough & didn't look as nice as the one in the pic.

This is what frustrates me about Olds builds... Performers are for low RPM grunt, Torkers are pretty useless compared to modern technology, and Victors are too big for the street/strip crew.

I really wish Edelbrock made RPM intakes for the Olds. Until then, try one of those Professional Products intakes and let us know how it does. If its a good intake, then that is exactly what you need; a high-rise dual plane.

I don't understand Edelbrock's reluctance to cast the RPM for the Olds and Buick 455's. I mean, they have one for the Pontiac and even AMC from 290 to 401's, for cripes sake.

For the money, even if the PP intake needed touched up, it's a deal, IMO.

I agree, but the Olds has a shaky following. Those other engines had intakes developed early when they were hot items. I think they could make money on it, but they procrastinated so long that its probably not profitable to do it anymore. BBO engines are small bore, large stroke, so their RPM potential is already limited, which was the original reason for skipping the RPM. They made performers for street guys, and then bigger race intakes for obvious reasons. I spoke with Vic several years ago (he was a sponsor of a TV show we were producing) and he specifically said that they were on the fence about making new RPM olds intakes, but at the time Mondello was tooling up to do the same thing. Vic decided to let Joe take the financial burden, and of course it never happened. Now its one of those deals where they aren't sure that their return on investment will be greater than the decrease in Olds engines use. Vic's analogy was like buying stock. You wait and wait until it bottoms out, but what if you miss the bottom? You keep waiting for the next slump but before you know it, the opportunity has passed and the stock might drop out after you make your investment.

its one of those things where you keep waiting to jump in, and the longer you wait, the less likely you'll have a market.

I think the time has passed

IMO, they should have intro'ed the Olds 455 RPM intake w/the 455 RPM heads. It's a no-brainer, for cripes sake!

It's like, here, buy these heads, but were not gonna make an intake to compliment it, unless you want a weenie Performer or an open-plenum Torquer or Victor.

Who knew there would be an RPM set-up for the AMC, but not the big Olds or Buick. Makes not a lotta sense, to me anyway.

I agree, I don't know why they didn't just make the RPM intake to go with the heads.

As far as trying that air gap style intake, it will probably be very similar to the Edelbrock performer intake I had on my previous 455. I would rather try something different like the torker.

Has anyone used a Torker on a big block Olds (or similar displacement B/B)?

How did the engine respond to it?

Thanks again

I put one on a 403 because it was laying around collecting dust. Probably the worst thing I could have done. Its a tiny single plane intake, so it has all the drawbacks of a single plane, with almost none of the benefits. It killed throttle response, cold operation, street manners, and MPG, but didn't flow enough to make any more power than I did before on the Performer. IMO, torkers are for show only. They're pretty old tech.

If it has any engineering behind it (I said IF ) it will be superior to the Performer, being a high-rise, dual-plane w/a cut divider and larger cross section runners, plus more plenum volume.

With a gasket match to align the intake and heads, it should be better than either the Performer or Torquer, IMHO.

I'll just say this- I would definitely take the chance if I were building another 455 Olds.

There may be issues getting it to fit under a hood, and w/things like carb linkage. Might be worth checking the Olds forums to see what, if anything, has been said regarding it.

yes to the torker...a big pain in the *** to bolt onto the engine. i wasn't impressed. i'd either use another edelbrock dual plane or try the pro form intake. one of my friends has tried it between the torker and the proform and did not see a noticeable difference.

You put a BBO Torker on a 403 SBO? How much of the flanges were left after the 1.5" was machined off of the width?

IMO, the best thing Edelbrock did AFA the Torquer goes was to NOT make it for the "little" Olds 350/403's.

I'd never bother w/all the labor involved to mod a Torquer to fit a 403- but to each his own...

Well, he did say it was the worst thing he ever did... LOL


Thanks for the replys - I'll probably just go with a dual plane. Since I'm using a Q-Jet, I'll probably go with the Edelbrock Performer....but I do have a '67 Toro intake I could clean up & use too

Good point!

Nah, it's for a 425. Same family as 400, 425 and 455 cubic inch engines.

Plus they are a "low riser" intake, one of the lowest out there (to provide hood clearance), w/the possible exception to those awful 472 Caddy intakes from the '70's.
