The old 207 cam made good power for a stock 3.8 and there are much better
lobes available now, but porting changes what you can do with the cam. Kirk's
setup runs well with a huge (by SPI standards) cam of 220* on the intake but
it also uses the modern fast ramp lobes and a HEAVILY
intake, about the most porting you would want with a 3.8 and about right
for a mild 4.2 setup. The 3 main things that make a V6 go fast are:
I would not recommend a cam like Kirk's for 99% of the NA 3.8 SPI's,
in fact, his setup is awaiting the supercharger which is where that big
cam will really start to shine! It is probably nearly perfect for the blower.
He also has 4.10 gears which offsets any possible minor torque losses
in the bottom end of the RPM range.
