Super 6 Set UP

If I read this correct, you are being offered a 2bbl carb, 2bbl intake, and an aircleaner off a a 225 slant with manual trans. If that is the case, you are correct. You can use your current exhaust manifold. I am assuming you currently have a slant without A/C in your car now. So, your current gas pedal assembly and kickdown linkage will not work with the new set up. Yes, ask for all the hardware! You will need a gas pedal assembly from an early A-body V8 or from an early A slant that had A/C. In addition, you will need a new throttle cable, and a means to utilize the kickdown function. I used a Lokar throttle and kickdown assembly. It is a fairly easy to install, and has worked well for me. I can't help you with a price for what you are being offered. There are lots of conversations on this forum explaining this whole process. Good luck!
