Installation:
I rated this a 1 on the scale due to the fact that other valve train parts have to be updated with this camshaft as well as the required head work that needs to be done. Due to it’s .449″ lift, it requires a dual valve spring conversion for Mexican OBDII heads. OBDI/OBDII German heads with OEM dual valve springs can sustaing the valve lift, but converting to a Heavy Duty set of springs is suggested. Also highly suggested is getting your ECU chipped for this cam to re-adjust timing/fueling tables and to raise the idle speed to smooth it out during idle. And along with those, new cam followers (lifters), camshaft oil seal, valve cover gasket, and upper intake manifold gasket are absolutely required for this camshaft upgrade. If you are not mechanically inclined, I highly suggest having a professional do the head work.
And speaking of head work, the stock ports on both OBDI/OBDII ABA heads do not flow enough to properly take advantage of the power increase this duration can provide. At the very least, having the intake ports “port-matched” to the intake manifold, along with a general clean-up of the inside of both the intake and exhaust ports should be done. I personally suggest a professional do the head work to properly shape the ports for maximum flow. I also suggest bumping the compression from the stock 9.8:1. More static compression with a high duration camshaft equates to more dynamic compression during operation. More dynamic compression equates to more power from the camshaft.
Performance:
I gave this cam a 5 in terms of performance due to the fact that it provides a great increase in top end performance with supporting bolt-ons and head work. It provides a power increase from 4000-6500rpms. It’s idle characteristic is considered lumpy due to the valve overlap, even with a raised idle speed. This camshaft is an ideal upgrade for both OBDI & OBDII ABA’s for all out performance. Lastly, this is NOT a camshaft to be used with forced induction.
Overall:
: 1I give this cam 3. Power increase is fantastic in the upper rpms, but the cost of this upgrade is considerable due to the valve train upgrade, ECU chip necessary, and required head work.
