Hello.
 

My name is robert and im out of texas. Just bought an fc and plan on dropping an ls in to it. Wanted to see if anyone can give me some insight im going to go cable but all i have is the throttle body need to find a pedel and what type of throttle cable to use.

You should be able to use your stock pedal.
The cable?..maybe look in the v8 conversion section to see what the guys have done for that.Also check GRANNYSSPEEDSHOP.COM. They list conversions and have some tech info.
