... MEC coils because I figured I didn't need to get HEC (High Energy vs. Medium Energy) because they are only firing once every 360 degree stroke of Camshaft, instead of 4 times every camshaft rotation. If you were wanting a standard replacement coil, then I would definantly get HEC. But in mulitcoil ...

... at the stock manifold it does look like a custom one with mandrel bends and a merge collector will flow a sh*t load better. I have a 'stage 3' camshaft 225/226 duration @ 0.050inch and was thinking a good designed manifold will reduce reversion and increase low end torque, economy and spool ...

Is there any point in upgrading the camshaft in these engine, are they restrictive in any way, and what power can you get from the standard camshaft if left in. Also is there any point putting a vernier pully on the standard camshaft if used.

Nope. Put seriously simply, retarding the camshaft promotes high revs at the expense of lower down torque. It moves the torque peak higer in the rpm range. The engne will live happily with retarded cam opening times but the real change comes from ...

... much of a difference if any. Actually with the number of ET's i've seen and heard of with N/A heads on them most are probably running with the NA camshaft. Best to contact a camgrinder like waggot tell them what sorta performance you want and they will grind you cam to those specs. Cost is around ...
