A new cam is the way to go now as previously stated, if you can stretch to a new 4-1 exhaust manifold and if possible a performance exhaust, to really make use of the engines new breathing abilities.
Change the air filter as well, no point in choking the engine!
One minor point ! Why was the crank lightened and balanced and the flywheel untouched? chop half a ton out of the flywheel and it'll rev like a motorbike !
It'll be a b!tch in traffic tho......
ps. that reminds me, don't use a radical cam if it's your daily commuter.
