I am going to replace my 305 CC carb with a 355 CC carb. I know it sounds silly to keep all of the computer stuff hooked up but I am kind of used to it. EDE suggested I look at some of your signatures to get an idea on what I need to do to get my 86 IROC to do mid to low 13's and still be streetable with the computer. I have been looking thru the sigs and see that most of you that use the computer run TPI. I would like to save money and not purchase a complete TPI setup, so if any of you have a motor like I am talking about, could you let me know? Should I give up the carb and go TPI (which I know nothing about)? Thanks in advance for your input!
