Question Big Block Throttle Linkage

For those of you running big blocks. What are you doing for a throttle linkage? I'm dropping in a 454 and was thinking a cable set up would be beneficial? My rides a 68.

Thanks in advance.

Re: Big Block Throttle Linkage

By 1968 GM was resolving it's first national motor vehicle safety recall in regards to their 1958 design of the motor mount. Just about every motor in the line-up by then was capable of breaking the factory vulcanized (glued together) factory rubber motor mount. As a result the motor would rock to the passenger side and with a throttle rod pull the throttle open. These "E-Ticket rides" resulted in natural selection taking it's course with those not smart enough to turn off the ignition, push in the clutch or to p[op the tranny into neutral (any one would solve the problem) to crash.

Ralph Nader made is fame but mostly fortune by suing to recall all GM cars with a V8 made from 1958 to '68 and having a five to torque strap installed on the cast iron exhaust that looped around the upper control arm to limit motor movement. In 1969 the motor mounts were changed and a cable throttle installed.

The only difference being the throttle hangs in the air on a cable car but rests on the floor of the foe board on a rod car. I used to pull the restraining plastic end off the cable style by being too vigorous in mashing the gas. Took a little to get used to the higher gas pedal as well. Today all cars are that way so you should be used to it by now.

Re: Big Block Throttle Linkage

In '68 and '69 the standard throttle linkage was a solid throttle rod and linkage between the pedal and carb. Only the inline 6 got a cable. There are plenty of aftermarket cable assembly's available but you have to replace the pedal assembly as well as the cable and the carb connections unless your car was a 6 cyl originally. I would just do something like this...

As for the engine mount recall it came in 1971 and included all 3 years of first gens and a total of 6.68 million GM cars & trucks.. Here are the facts...
