So When I see my friend with the 1971 Hemi Roadrunner, I'll be sure to mention that he should chuck his twin Carter AFBs in the garbage and replace them with Holleys just like you and the other misinformed individuals are suggesting right? No problem. Both the parts manual and the chassis manual are excellent resources of information. It takes no skill to read a chassis manual but certain training to read a parts manual. I am guessing that you simply don't have that training.
