I truely believe Jack does good work, but, It comes at a price, like most other good engine builders. If your trying to stay on a budget or don't see needing a fully tilt race motor, there are lots of other ways to get there. For our modded LT, the stock pipe was junk. With the porting I had done and the other mods, the stock pipe just did not let it run. I used a FMF on it and it gained a bunch of power and speed. Like I said, Jack helped me a bunch, and I'm not trying to bash him at all. just don't count short what can be gained by trying different setups.

 

Before i do any mods im gonna service the trans ,the top end was just rebuilt so with a fresh trasn service it should be perfect.

 

anyone happen to know a place that has a copy of the service manual online?
