Posted this a while back with no response. Figured I'd put it in here this time with hopes of better luck. I was going to do my lifters soon in my 89 KA and I figured I might as well gain some HP since they're gonna take the cam out anyway. Do have an idea what kinda HP I might get with this cam on a stock motor? I asked Summit and they said "there are to many variables to determine such as what header, what intake, what injectors you are using". I told them it was a STOCK motor. How can I make it any more clear!!!!!!!!!!!!
The only thing I have is a cone filter in place of airbox and a 2.5 exhaust.
Here is link, hope you can give a general idea.
