Now intake selection, was: rocker arm ratio and cams

Whatever you do, get the 2bbl MPI intake, not the 4bbl MPI. I have the 4-bbl
intake and it makes incredible top end power, but at the sacrifice of low
end torque. Back when I bought it in December 1999, it was the only one
available, but now you have a choice. Another interesting note was that the
engine makes peak HP at 5400 rpm but was still making power at engine
cut-off. The bad thing is that the cam makes power from 3000-5400 rpm, a
mis-match is what I suspect with the two because the intake wanted to rev,
and the cam wanted to quit. I plan to either switch to a 2-bbl MPI or finish
building my stroker 406, which would be perfect for the airflow of the
intake. If I had a 406, I feel it would work perfectly, but after
experiencing the torque of Sam's motor, I would rather have the torque.
