Look at the numbers. The upper set are for the HO cam, notice the total
lift is higher, it also is a bit longer duration than the non HO. That
difference and the computer programming to match it is the difference in
the engines. If you want the extra HP you have to do more than swap
computers or PROMS. For 5 HP it isn't worth the effort. A good tune up
will give you a bigger improvement. Now IF you were getting 20-30 HP it
becomes a marginally better upgrade BUT only if the engine is coming
apart for work anyway.
Well Steve W.
I have a vin x with a long air tube going to the middle of the motor, bu
t the cover says votec now I really don't know what I have.I just bought th
is 1997 s10 less than 2 months ago. 160000 miles it will fly. The owner's m
anual doesn't give you very much information on the motors, like bore, stro
ke, so on. I do have to ease down the gas to keep from barking the tires wh
en I take off from a stop.
Seems as if we have a smartass in here. Very well, everyone is entitled to
their opinion. The only reason I ask all these questions is because I'm not
that well educated in this area, I know enough to get by, but I like to ask
questions. I just had people at the dealership telling me one thing, and
then I heard totally opposite from you gentlemen. Though I should have
listened to you in the first place because my dealer has been wrong in the
past, but I must say I have learned quite a bit from everyone in here, and I
thank you. I took auto service classes in college and high school, but
nothing extensive. My main love is computer science and programming. Thanks
again for all the info. By the way, from what I noticed, this Chevy forum
has dodge, and ford beat by a long shot, way more users on this.
