Hi everyone j want to knw if the rochester quadrajet woul work good with the 455 torker i take on my 1968 442 with the 455 motor?? Any suggestions or tips i want more torque on my 4-4-2

Torker is a single plane intake designed for higher rpm use...however, even moderate improvements to a stock 455 will justify the use of a Torker.

What have you done to your 455?

Orlando Perez

Nothing yet we just got it running two days ago but the carb is not working good it appears to be stock or too old im guuna have it rebuild but i bought a torker intake and i was wondering ifi the quadrajet woul fit and work fine with it.. What you guys recommend should i live it stock and just rebuilt the carb or buy a new carb?? Its a 68 442..

The Torker is made for a quadrajet. I would have it rebuilt, and I know the perfect guy to do it. His name is Danny Sarvis, he's in San Antonio. For what he does and how well it will run after he's done, you can't beat the price. I'll pm you his information if you're interested.

Pilot im in chicago but im gunna listen to you i will have it rebuild and install it with the torker .. How much hp im lookin to get with these set up ..

ah64pilot

That's the problem, you haven't changed anything else with the engine. Just adding the intake manifold and rebuilding the carburetor may not necessarily give you more power than stock, but it will give you more power than you have right now since it's not running properly.

You have a '68 442 with a 455...what heads are on it? Do you know anything else about the engine?

Orlando Perez

All i knw its that the motor its a 455 with a 4 speed munci trans and thats it .. Its my first muscle car and i love it

ah64pilot

Well, I'll send you Danny's information and he can rebuild the Q-Jet. That'll make it run a ton better than it does now. Then if you want to add other stuff later on at least it will handle whatever you throw at it Check your pm

Orlando Perez

Ok thanks i appreciate it..

Hey Steve i wouldn't mind having that info for my future build. i have an electric choke and manual choke Q- jet and im using the performer RPM intake on a 79 350. Which one should i use if i were to send it to him?

firefrost gold

I would go with the electic one if it was me. But then Im not steve so you didnt ask me . You can block the cross over and gain power and that way and you dont have to find or work with old linkage and parts to make it work with the intake.

ah64pilot

Uh, don't ask me...my Q-Jet experience is limited to giving you the name of a guy that can build them correctly. My answer: A Holley HP 950? lmao!

I'll send you his info and you can ask him...or take FFG's advice. Check your PM.

Check the numbers on those carbs driver side on the carb body. See which one flows the most and try that one out! The electric choke fits many years. It may interchange between your carbs

Jefhay6814

LOL i hear that!

Jefhay6814

What exactly is this crossover you're speaking of im a beginner lol. im learning off of these damn forums and books i've been reading

Jefhay6814

Would i just google the part numbers?

11971four4two

google the long # starts with a 1 or a 7

example 7042953
Good luck!

Jefhay6814

ok cool ill do that when i get outta this boring *** class im in lol

11971four4two

You can always post the carb numbers here on classicoldsmobile. The members here can be a great resource

Jefhay6814

Most Definitely

The crossover is where the heat will come up and run the choke . If you block it you get a cooler intake or so the that is the reason ?? if it is a real deal or another speed trip . You can get gaskets with plates to block them or some will melt pistions to fill the void , or slugs can be fit to block it at the intake and head and intake .

Jefhay6814

Oh ok

firefrost gold

I see you have Bill Travatos book that has lots of good info in it google BTR olds builds or go to V8tv and see he has a 9 or 10 group of how toos on a olds build up I will see if I can find it and link it.

Orlando Perez

Well i saw a big E on one of the heads but am not planning to rebuild the motor yet maybe next summer i just want it to run good for now im replacing the water pump,fuel pump,tyming chain and should i replace the cam and lifters what you guys think???

DeltaPace77

Maybe a couple suggestions. From experience, a dual plane intake like the Edelbrock Performer, makes a lot more low end torque than a single plane. Don't think I'd use a Torker on a stock engine. Also, Q-Jets are excellant carbs, when properly set up for your engine/gearing combination. This can be a problem, when sending out the carb for your present stock set up, only having to do it again later, when changing cam, heads and exhaust later on. If you mention this to the carb builder, will likely give you break on later tuning. Lars Grimsrud and Cliff's Performance, are also very good with Q-Jets. Contact Lars v8fastcars@msn.com, and he'll send you his tuning papers at no charge, telling all about Q-Jets. Lots of good information here.

Orlando Perez

Ok i get it .. So im replacing the the intake snf had the carb rebuild already what else would you suggest to replace how bout the timin chain and fuel pump and what would i get if i replace the camshaft and lifters..? Oh and does my 68 4-4-2 suppose to have a posi rear end.. Sorry but its my first muscle car..

ah64pilot

I would wait to do the cam when you are doing a proper rebuild. Just stick with the stuff that may need replacing now...water pump, fuel pump, timing chain, etc.

Your car should have posi but that's not to say someone didn't change it out during it's lifetime.

Orlando Perez

Well i found396021 F estamped on the block and a E stsmped on the heads of my 455 what does these mean?? How much hp??

ah64pilot

Well the heads are from a 1970 engine. The block you would need the vin derivative off the flat spot on the front left corner of the engine to know. Either way, it won't really give you an accurate horsepower number...especially if the engine had been rebuilt previously.
