Yes we are using gross jets. All the hipe says that they are the best,
apparently not!!
We will try replacing them with standard jets. We will do a complete rebuild
to the engine,
with an S-2 cam, balance, hard seats, complete head job, you know, whatever
it takes to
go fast!!!!. I keep telling Scott to think WEBERS.
