hey guys whats going on. Im new to the forums and Ive got some questions for the experts. Have any of you ever used an MSD ignition box? Did it work like it was supposed too and have a long service life? What about a good set of headers for a k5 with small block? My 86 model has a goodwrench 350 with a small cam,intake and performer carb. Im disapponted with the carburetor, it stalls under heavy breaking. Any suggestions on a different model or brand. Ive had several 4wheel drives, but this is my first blazer and I really like it. look forward to hearing from you guys.
