Detuning 380hp create engine.

I thought of the Rhoads lifters but the ones that take 15-20 degrees of duraration needs adjustable rockers plus the lifters which is double of the cost of the cam it self.
And still be on 108° centers instead of the new cams 114°. They both have similar lift and is only 14° smaller intake duration at 0.050".

The cam that's in it is actually fairly streetable for the size even with the weak 2.96 gears that came with it. Was gonna swap in 3.91-4.10 but remembered what I wanted when was looking to buy a car this summer was a fun daily driver. Not a week end machine.

Gonna save the cam and intake for another project.

Any idea if the stock spring will work with the new cam ?
