Well I did the Holley thing and the secs do open all the way. I also do notice a good change in go with the all 4 and not just 2 tied off. At 3000 and up, 4000 max for me, is where I see the muscle.
Twisted,
I have changed the springs long ago to the light springs. I also have to say that Holley has an OK product out of the box but needs finessing.
Tony,
Haven't had time to do the vac thing yet.
Not sure what to think just yet.
Any thoughts is always good.
Thanks for your guys' help.
I'LL KEEP TRYING.
Luis
