Carb Linkage 6 cyl. to V8

Well, looking ahead, and trying to get my mind off my clutch/motor mounts/header problems...

In switching over from a 6 cylinder motor to a V8, will I need a different linkage setup from the firewall to the carburator? The setup I have is for a 6 cylinder and mounts way over to the side to line up with anything for a carb that will be basically centered on the 350 motor.

Re: Carb Linkage 6 cyl. to V8

Where is a good place to get this from and what would I need. I would assume the part that goes from the rod under the dash, through the firewall and to the carb...Is there a kit or what would be my best option? I am putting in a 350 motor with a 4 barrel holly carb.

Original equipment is the right thing to do but a cable setup becomes nice if you're not into making a copy but are more into a hot rod.

Re: Carb Linkage 6 cyl. to V8

if you aren't playing the "originality" game, get a gas pedal and cable out of a 70-74 nova and switch it over to a cable setup. well worth the $10 you'll spend at the boneyard for the parts, and the 1/2 hour it will take to bolt the pedal up and drill the hole.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

Re: Carb Linkage 6 cyl. to V8

I am still not sure which way to go, so I thought I would post a few pictures of what I have. I have read a lot of posts about different setups based on different carbs, and cable -vs- rods, etc. From looking at Classic's catalog, and a few posts, there should be a rod that connects to the accelerator bracket that bolts to the firewall. Since my existing 6 cylinder cable comes out of the firewall way over to the left side, I would assume I need to get a longer rod from the gas pedalinside, that extends out the bracket on the firewall, and connects to another adjustable rod that runs up between the motor and the firewall. Is this correct, or what are my other options? Here are a few pics...

Go with the V-8 Nova cable already suggested and buy the cable bracket for the carburetor end from Ground-Up for use with a Holley carb.

Re: Carb Linkage 6 cyl. to V8

Your third pic, the engine side of the firewall. Plate with 2 bolts is the gas pedal pivot. On a V8 setup, that hex bolt coming out the side of that plate isn't there, the shaft continues into the engine compartment. A verticle lever attaches to it, and the throttle rod goes from that lever to the carb.

The easiest thing to do would be to buy a complete V8 throttle setup froma repro house. There would be no fabbing or messing around, it would just fit and work.

The Nova setup is a good plan, too, but might need some fabbing. Best would be to buy the whole thing in a junkyard. Next best would be to get the cable from a parts store or chevy dealer. You would also need the bracket that holds the carb end of the cable, and possibly some holley stuff to actually attach the cable to the carb.

A solid throttle may "move" with the engine. The 406 I had in a 67 long ago did a lot of this, my currect 68 does not. This can feel a little weird if the motor is moving around a lot on the mounts. A cable throttle does not pass engine movement to the driver at all. Still, lots of us do just fine with a solid linkage.

Re: Carb Linkage 6 cyl. to V8

If I wanted to buy a new setup for a gas pedal and cable out of a 70 - 74 nova, how do I know where I need to drill the hole in the firewall and all of the details of how everything hooks up under the dash and bolts to the firewall? Is it basically the same bolt up at the firewall as the camaro has? I guess I am not sure where to drill the hole, and how the cable is routed from the pedal to the firewall and then to the carb...

The V8 Nova cable is routed in the place your 6 cylinder cable is now. No holes to drill.
