Porting a Torker 2.0
I recently went back to a stock hood and got my hands on a free used Torker 2.0 # 5061 for my 454.
I'm also fully aware of the potential shortcomings of this intake, as I had one on a 396 years ago, and switching to the RPM made the car feel like it had an extra 50 cubes down low. Yet, here I am.
As we all know, the ports on this thing are goofy as heck. Not to mention Ive noticed a bit of casting flash in some of the runners.
Has anyone ported one of these things, and is it even worth my time to do so?
Thanks!

The ports on those are just small......real small........the best thing to do to it if you must run it is have it extrude honed........
The only other choice for square bore is the LS-6 pancake intake......which has much larger runners......
People have seen over 500hp with the LS-6 intake but I doubt very highly the runner cross section is even enough for 480 or so with the Torker 2.......I think if you could get the runners big enough, it would work well.

Jebby and Mel, thanks for the input.
That Pontiac thread is interesting regarding the port shape... I think I've read through that one before.
When I first put this motor in, I put on an L36 intake, and the QJ from my Ls4. The QJ was dying and I put on an 800 spreadbore 6212 Holley. It ran o.k, but considering the disappointing track outing with this setup, even from an mph standpoint (motor is a used Mark Jones unit that did 11.8 @ 116 or 118 in a 70 Chevelle), I started to change it up... L88 hood, rpm intake, 850 proform etc.
I collapsed a roller lifter a couple of months ago, and I got sick of looking at the unpainted hood, so I've come full circle. I considered the ls6 intake, but the Torker was free.
Ive got the proform 850 and an older hp950 (really like 830) I got from a friend for a song. I'm thinking if it's not as responsive as I'd like, maybe an annular booster carb will help out.

at least it is aluminum. can't beat the price. electric 40 buck harbor freight die grinder. if you grind through to atmosphere epoxy it up. if you grind through to water... it was free after all!

As much as I can tell you and I probably share similar philosophies, Im also a lazy man.. right now I'm leaning toward bolting it on as is
If my new lifters dont come soon, maybe I'll work on getting rid of the casting flash.

The POS Torquer has very short runners. Easy to grind out using a air die grinder and aluminum bits. Just ensure that you tapper the ports down to the exit size. It will increase port velocity.

Actually in the old days ( late 70's early 80's) There wasn't a lot of choices on so called performance intakes and they were often geared towards smaller production stock type heads. Like I had a tunnel ram SBC with tiny ports probably made for the common double hump heads somewhere around 170 cc or less. I was trying to mate them up to newest 200 cc sportmans heads with 2.055 intake valves. I had to weld on the top side of the runners adding metal before I could begin to contour the much larger ports.
Once you get it all bolted up you should consider a 4 hole wood carb thermal spacer. The height of the Torqer doesn't give the carb good booster signal. Plenum is too close to the carb base

cant help but wonder if he did some porting and used a 1-2" super sucker if that would pick his signal up....but may have hood clearance issues. Those pick up good around 4-5k

GKull and Cuisinart... I have been thinking about spacers, especially the super sucker.... but, theres always a but... theres an article comparing the TII, Performer, Victor Jr, RPM and Air Gap on I think a ZZ454. Naturally the Torker was the worst, but it was able to match the performer in overall figures. They found that a 4 hole hurt the power, suspecting that it rammed the flow into the floor, but a 1.5" open spacer made the best over all power. But with that said every combo is different.
On my 74, I think I could get a .75" spacer in there, and thats about it. I may have to try a few things, but I look forward to borrowing an annular booster carb and seeing what that might do.
When I finally get my Richmond 5 speed OD back in, Im sure it will help wake up the bottom end response with the extra gear.

Annular boosters are actually a CFM restrictor If you flow bench measure a carb that you have done a bunch of machining to get the highest flow and add annular boosters you might loose 30-40 cfm. single planes require less cfm than their dual plane siblings
You can skew any test you want! especially if you install a 3.5 power valve on small cammed big cubic inch motor with high vacuum. The A/F curve is going to be all screwed up and favor the highest port velocity

I read that whole article and it wasn't done well on optimizing the carb for each combo. It also shows that it is futile to put a low rise intake and then have to throw a tall spacer on it. They also didn't explain that the 950 of course would work better on a dual plane and the annular booster 850 is more suited to big single planes and a 4 hole spacer. single planes benefit by 4 hole. dual planes like single or two hole spacers depending on what you are trying to accomplish

Ive been very interested in annular carbs in the past few years and really want to see what its like. Ive considered efi like Sniper and FiTech, which uses an annular type set up, but Im afraid of having new variables to cause new problems that I didn't have with a carb.
Of the annulars, I find the 9381 and 9380 to be very interesting, and of course I could always swap a QFT annular main body into either my proform, or even my 950 hp.
Just to get rolling, the Proform is going back into service first, since it was the last unit running on the car. Eventually I'll try the 950hp, and have a feeling that the smaller venturi might equal better throttle response.

Friend ran an 89 TA in the nevada silver state classic. lingenfelter did a carbed 383 for him used the Torker 2. Little light on low end but who cared. Moderate/ FT the car hauled *** and came into its own at 5kcleared the hood. basic build, 5 spd 4.11s Not bad...

is this the same intake? or is it eddy pulling out an old name and sticking it on a new intake? and if so, does it fit under the hood? https://www.trickrides.us/product/bb...utm_term=36625
