Intake manifold choices: weiand or quick fuel

Hey guys, thinking of changing my intake from an edelbrock torker (really old one) to either a quick fuel QFT-701 or weiand 8120 possibly 8150.
I've read good things about weiand but haven't heard anything about the quick fuel.
It's going on my (soon to be) daily driver '69 el Camino. I'm only concerned with street performance, as much as I'd love it to be a street/strip car I'm being realistic.
My setup is 383, quick fuel 750 carb, unknown aluminum heads (allegedly speed master), comp cams xe-284h cam. 2.73 rear gears and pretty much stock everything else.
What do you think?

1. I think you need waaaaaayyy more rear gear with that cam.

2. I like the tall Weiand 8150 or Edelbrock 7101 or any other tall, dual-plane intake manifold for a street motor. If you'd like to save a few shekels, peruse the national craigslist for a used Weiand 8014 Stealth or a Holley 300-36 Street Dominator. My choice of the whole mess would be a 300-36.
All of Craigslist

I've never used the QF unit, but looking at a picture of it, it appears to be a tall manifold, although QF says it is rated to only 5500, which would be the range of a short intake. A tall dual-plane like the part numbers I listed above will make more power under curve than any other type of street manifold from 1500 to 6000.

Do yourself a favor and experiment with spacers. Try 3 or 4 different combos and choose the one with the best results. Make 'em out of wood (minimum heat transfer) and drill the holes with drill bits and hole saws.

Do you know what the static compression ratio of the motor is, or did you just throw a cam at it without knowing?

With those gears, I hope you are focusing on performance in the 80-120 mph range, because with that cam it's gonna be a slug until you get to 40 mph.

Have a look at the Summit #226012, about $75 cheaper for the same type manifold as the QuickFuel.

The cam was in the car when I got it as was everything else but the carb. To its credit the thing will chirp tires from a light with anything over 1/3 throttle. But I do plan on switching to (most likely) 3.73's with a 700r4 for highway.
So from what I gather taller dual plane with a spacer is the way to go?
Also the thing I liked about the ones I originally posted was that they come in black. Everything is better in black lol.
I'll take a look at some of the summit ones as well though I've heard mixed things about the quality.

Nah, you don't want to do that. The operating range of the cam will not produce enough torque at 2000 rpm's to do you any good. Mileage would probably be worse than it would be with a 3.73 and 3-speed tranny, with the motor up on the cam. The motor would need a pretty mild cam to pull at 2000 and be efficient.

Performer RPM and Weiand Street Warrior 8150 are both excellent all-around intake manifolds for 350 and larger small blocks. However, I think the Edelbrock is a nicer casting. (A Holley guy I know said both manifolds show similar performance on a dyno.)

Yeah, that cam and axle ratio won't play well together. A MUCH smaller cam or somewhere around 3.50 gears (+ or -) is what the car needs.

Heck, my pickup has 2.73 gears, and even the mild, well-tuned 355 is sluggish for the first 50-100 feet. Sure is nice on the highway though! That said, I'll probably change to 3.08 or 3.23.

3500 rpm stall converter, RPM Air Gap manifold and 3.90:1 gears.

With your older Torker you may only see a gain of around 5 HP with a swap, you might try experimenting with spacers instead.The later Torker II is worthless.Take the advice above and do a gear swap,3:73's with a 700R4 will get you out of the hole quick and the overdrive will make for good daily driver cruising.

Trans and rear are on the list of things to do now.
The goal with the intake was to get a better power band where I'd use it since the original torker was rated at something like 2500-6500, so I figured either an idle-5500 or 1500-6500 would feel better around town.
This is all stuff to consider though, I appreciate the input!

Your earlier Torker does not have huge runners so port velocity will still be fine at lower RPM's with the 383 range should be around 1500-6000 after you do the upgrades with transmission and gears you will be into the power band sooner,you could advance the timing chain 4 degrees to bring the low end in sooner.

Instead of the 700 trans, I'd opt for the 200-4R because of the gear ratios. Then you could get with a 3.90 or 4.10 gear without 1st being a granny gear and still have a nice O.D. Remember your cruising speed should within the cam's "happy" zone for efficient cruising.

I have the weiand 8150 intake on both of my 350 sbc builds and it has done excellent with a lunati voodoo hydraulic roller 219/[email protected] 515/530 lift with dart shp 180cc aluminum heads and 9:1 compression and a 2000 rpm stall and 3.42 rear gears and also with a lunati voodoo hydraulic roller 231/239 @ 50 535/550 lift and 9.5 to 1 compression and a 3000 plus rpm stall and 3.73 rear gears and dart 200cc iron eagle heads ported and cleaned and both builds give me 19 mpg with a holley double pumper and a vacuum secondary. Also just to let you know the summit intake that is rated as a high rise to 6500 rpm is the exact intake weiand sells as there 8150 as when I got the summit one several years ago for some other build it had the 8150 part number underneath just like mine did. The same with the up to 5500 rpm one as well. The only difference is the one has summit molded on the top and the other has weiand on the top. I like them over the edelbrock ones since they have the extra fitting for adding a pipe thread peace so you can add extra full manifold fittings if needed and will not cause any issue with a holley double pumper like the edelbrock brand does but edelbrock is pretty much the same height from the rpm compared to the speed warrior. Both of my engines go over 6000 rpm and still pull.

What do you think?

What kind of street performance stop light to stop light, stuck in creeping interstate traffic; or cruising on the interstate at 80 mph?. Or some ratio of these.


You definitely have too much cam for the rear axle ratio. The Comp XE268H is a great street cam, it doesn't need a high slip converter though it's on the top of that range and it doesn't need 4.11 gears to get launched.

My lunati voodoo cam is 270/278 and 21/227 @ 50 wih 515/530 and has a 112 lsa and it has about 17 to 18 inches of vacuum in park with a turbo 50 and a 2000 stall convertor with a 3.42 gears and with my engine setup with a gm block and a high rise intake and a set o dart shp 180cc heads in a 96s10 with a custom made double pumper 650 holley i get 19 mpg and i bet I could get a little over 20 if i did just little more tuning. My cam is a hydraulic roller
