Hi I am currently running a kb 2.3 just wondering how drivability will be With a KB 2.6? Or should I go bigger then KB 2.6? I only go to the track 2-3 times a year so more cruising. I have a JLP short block,R heads,stage 2 cams, full comp R exhaust, dual walbro 255's, 60lb injectors,Etc. What kind of power do you think I will make on 93 octane also?
