69 Barracuda no power

What are you running in your roadrunner?

I read your post several times over and found nothing that indicates the 318 is not running as it should...maybe, just maybe the rebuild wasnt for power and without knowing if they addressed the relatively low compression ratio AND found a cam that works with the engines compression ratio...you might just have a 250 HP 318 and are expecting more then you should?


(I'm not trying to be a jerk, but it is something to consider)

Having said that, start with a good tune
Get your timing dialed in and idle set up for maximum vacuum and go from there
