So the 455 is going back together, 1970 block .030 over, shallow dish high compression silver o lite pistons, C heads with air bumps removed, hardened seats, w&z exhaust manifolds, erson tq40h cam and stock gm hei, and the original rebuilt rochester quadrajet, so my question is, what will work best for an intake? I have a stock 1970 455 cast iron intake and I also have an edelbrock torker, I am.planning on a 1800-2000 stall converter and 3:23 over the winter. Tech at erson said any aluminum intake will work good with the setup I have, I have read performer isn't much of an improvement over the stock, I'm just curious if the torker is the way to go?

Where did you read a performer isn't much of a improvement compared to a stock cast iron intake? JMO get a performer.

I seen a few different articles saying it in hot rodder and a few other sites, it's on the internet so it must be true lol. I'm.just not sure what would be best for my setup, the stocker or the torker, I'm not buying a performer, I'm already way over budget on this build. I'm just seeing if a torker has an advantage

Another 1 of the articles was on here, March 11 2016 by high 11's. Again, I'm not sure if there is truth to performer vs stock, I honestly don't know. I'm just trying to see if a torker is worth using or if it's overkill for my setup

people really beat on the torker being a single plane on a slow rev-ing big block..but they have small runner cross sections and are pretty flat..

whats the power range of the cam etc..it all works together..where does your engine fit in the description?

torker precs off their site:
Torker 455 intake manifolds from Edelbrock are single-plane, low-rise designs, intended specifically for Oldsmobile 400, 425, and 455 c.i.d. big blocks for the street. They deliver crisp throttle response and strong power from mid-range to top-end--from (((((2,500 rpm to 6,500 rpm))))--and are a good choice for applications with limited underhood clearance. Their design won't fit Toronado or 4-4-2 Ram-Air without hood modifications.

The Performer 350 is similar to the factory iron intake but the Performer 455 is drastically different than a factory iron intake. It's more like a small block Performer RPM compared to a factory small block intake.

I don't have the cam card here, it's at the shop, but ersons description for the cam says, good low to mid range torque, usable power up to 5500rpm, recommend good flowing intake and free flowing exhaust. My thoughts were with 1800-2000 stall, 3:23 gears and duals with w&z manifolds I would be good. But, I am not an expert, that's why I am curious if the iron is better than torker for my application. Cam specs are 220/228@50 and 499/504 lift with 110° separation

is it better than stock..yes..just the weight off the nose will help too..

would i use it..no...id use a performer...if i had a stick dang right id use the torker...they just love sticks..

I don't get some of you guys. Unless you're going to slip the clutch till 3000rpm what does that matter? The Torker doesn't make the low end or midrange the Performer does on a mild build like his, with any trans, plain and simple.

Sell the Torker & buy a Performer. It is the best manifold for your build.

marxjunk

yeah, its called a clutch dump...instant rpm range of the intake..seat of the pants banging gears street fun stop light to stop light...

seriously though..i said performer...make it all work together..and posted info tomake a choice....i said its what i would use..not what he should use..

hope this helps

Another good intake for a mild build is the Edelbrock O4B.

oldsmobiledave

The O4B will work with the OAI on a 70-72 but nothing else other than OEM will work without mods.

Aluminium beats iron on weight. Dual plane beats single plane at low RPMs, which where you take off and will be much of the time. Any possible gain with the torker over a dual plane at higher rpms is minor and short lived and you lose power the rest of the time.

I would use the stock intake before the torker, but to get the most fun and performance you would really need to look at the transmission and converter used, but that would cost more money. Depends on what you expect, and how much you expect to drive it.

I ran a Torker with a converter that was way too loose, flashed around 4800. I finally got a custom built converter and wanted it to flash to 3600-3800, but it only flashed to 3300. It was a huge improvement over the very loose converter, but I felt it was a little bit lazy on the hit. I could have either pulled the converter to have it loosened 300-400 rpm, or I could have tried the Performer intake. The intake was much easier, and I already had one. It picked up .040 in sixty foot, a tenth and a half in the quarter, and only lost 3/4 of a mph. Eventually, the combo went 10.96 @ 120 with 1.44 sixty foot. You don't have anywhere near enough converter for a Torker. Either use your stock intake, or sell the Torker and buy a Performer.

Run the performer because you're close to stock.

I run a torker because the 455 makes plenty down low to start.
However, I have a cam that comes on at 2800, a 700r4 with a low 1st gear and am turning 4.10 rear. Bottom end had a girdle and forged rods so I can twist it up a little more too.
