Just wondering if anyone had any opinions on Compucams 2032? Ive got one in my TPI 383 sbc
Compucam 2032 Hyd. Roller Cam
- Thread starter Johnatthebox
- Start date
are you referring too this, cam info linked below,?
obviously Id need to know the engines compression ratio,
the cylinder heads,headers, gearing, induction,transmission,converter,
the car and drive train it was used with and a good bit more info
before a valid
analysis

Crane hydraulic roller camshafts are a good reason why virtually all pushrod-style engines manufactured for over two decades are equipped with hydraulic roller cams. Simply stated, the best way to get a wider torque band is to step up to a hydraulic roller cam in your small or big block Chevy, Ford, Mopar, AMC, Olds, or Pontiac. The roller cams' ability to quickly open and close the valves allows for more sophisticated camshaft profiles, while the hydraulic lifter body eliminates the need to constantly set valve lash. Crane Cams has the industry's largest database of camshaft profiles. This enables Crane to provide you with the camshaft that's ideally suited for your application. They also have an exceptional "flat" power curve and are a popular retrofit into older engines. Crane hydraulic roller camshafts are the starting and ending points for your camshaft needs.

your compression's a bit lower than ideal ,thats hurting the potential,
3.73:1 rear gears would help,
you failed to indicate the dart head port size,or fuel injector flow rate,
but from what you did point out Id suspect the power band falls closer to about 2400-5700 rpm ,
not a big deal as the transmission shifts around that upper rpm,under w.o.t.
youve more than likely got a slight rumble idle,
off idle up too about 2100 rpm,response is not as good as it potentially could be,
and power will fall off after about 5700 rpm if you kept the stock injectors.

head port size 180cc
fuel injectors - Accel 150826 26 lbs/hr
if you had to make a rough dyno estimate on this motor, what do you think?

Ok thank you. If you had to make one improvement what would you change?

This is the motor in my el camino. Its my daily driver. I was just wonderin if this sounded like a good combo? It was built by someone else, so I had no input on any of its design. Im happy with the power it puts out. Its a lot of fun. I think it couldve used a little more cam.......

if the compression's that low, as you stated a bit more cam duration,
would just further degrade the lower and mid rpm torque and responsiveness,
with very little in gains in peak rpms range,
to effectively increase power youll need to swap to a bit larger injector 's
porting the stealth ram base would not cost you much but would gain you a few extra hp, ,
if you do swap to a cam with more duration,
and of course that would benefit from increased compression

btw I also port matched the lower runner exits too the head ports
porting the stealth-ram base and port matching the intake too the cylinder heads allowed a 300 cfm flow, its significantly less unmodified
most guys I know have done the port work themselves and yes it takes a lot of time and effort but everyone I know thats done it feels it was worth the effort
don,t forget all that potential extra air flow from a correctly ported stealth ram intake and matching heads that can flow in excess of 300cfm per runner, requires 36lb -44lb injectors and a cam with enough lift and duration to allow that air flow rate to be effectively used if you expect the intake to perform to near its full potential
porting the runner entrances like this helps flow significantly
