Super Chevy – October 2019

Of course, the easiest way to get more

power is to slap on a shot of nitrous,

so we did. In this case, a Zex plate

system with some jets (. gas and

. NO) that should add another

 hp to the equation. The SP has

hypereutectic pistons so we stayed

conservative and made sure to back

down the timing  degrees.

And the SP gobbled up the nitrous

with glee. The hp number shot up to

 hp, a gain of  hp, and torque rose

to  lb-ft, an increase of  lb-ft. Perfect

for a trip to the local dragstrip. The SP

easily handled that small shot.

As we said, the SP ships with a fairly

mild cam, which makes it a great cruiser,

but what if you want something just a

bit more rowdy? Well, to get a bit more

power we picked up a cam from Howards.

The new stick came in at /-degree

duration with slightly more lift

(./.-inch), and a more aggressive

 LSA.

Howards

suggested

we move

to a better

valvespring

so they set

us up with

a set of their

beehive

springs and

the required

retainers and

locks. The

stiffer springs

should come in handy with the increased rpm we’re expecting.
