nope it has keith black 10 and half to one compression flat tops with reliefs and a purple shaft cam new springs high volume pump, the orange box, its brand new and was fine now its right on its face, the timing is the same, no vacuum leaks present the power booster works fine for brakes, it idles at 1100 to 1200 and around 900 in gear to stay running, surges at idle and driving, its almost like something is stuck, the bowls look half full through the site glasses nd no matter where i put the mixture screws for air fuel it runs the exact same, it should change a little.i sent the tech support the issue but havent heard back its strange i drove the thing 30 miles one night and it was fine and then started heading down hill fast.
the tech just emailed me saying it wounds like a blown power valve or split power valve gasket . I had holleys that blew the power valve and never did this/
