Hello,
I'm new here and have had my 72 C10 for almost a year. When I first got the truck the previous owner had replaced the original 307 w/2bbl with a 350 w/4bbl Edelbrock. From the get go it had a fast idle and come to find out the throttle cable is about a 1/4" short from letting the throttle go clear to idle. I'm assuming that the cable is too short because it was for a 2bbl and the 4bbl has the throttle linkage farther forward. Would a throttle cable for a 4bbl truck remedy this problem? I originally "adjusted" the cable bracket to get it this far, but a had a good mechanic buddy of mine replace the 350 turbo tranny with a 700R4 and I think he changed the cable bracket. I'd just as soon fix it right this time and be done with it. I see LMC lists 3 cables for a 4bbl. Would one for a SBC do the trick?

Thanks!
Richard
