I installed a 4bbl Holley 570 carb on my 318(originally 2bbl). I bought Holley p/n 20-7 and 20-36 since the manual said I would need it for a Chrysler application. http://www.summitracing.com/parts/HLY-20-7/ and http://www.summitracing.com/parts/HLY-20-36/ The kickdown doesn't seem right. Does anyone have a pic of the kickdown linkage on a 4bbl carb? I drove it around and it wasn't shifting correctly. Any help would be appreciated. Paul
