Hi guys, I'm new to the world of 4AGE. Will it be cost effective (dollars/power increase), if I replace my inlet cam with a 256 duration / 7.9mm lift cam, leave the exhaust cam standard and get some adjustable cam gears to dial it all in. The motor is a stock big port with freed up exhaust and a K&N panel in the standard airbox with a revised cold air intake. It is for a rally application so i really want to leave the internals of the motor standard for reliability and am basically chasing some simple "bolt-on" power for the right price. Have done a bit of searching and have come up with this as a possible mod, but want to find out if anyone has done this or if anyone can comment on whether it is worth it. Sorry if this sort of question gets dragged up a bit
