Is that the voodoo 60104 by lunati(voodoo 276?).  If so... and I think it is.....real good cam choice.

Which dart pro 1?  Is it the platinum?  180 or 200cc?

Depending on the variables I can see it making a solid 425 horsepower and should run low 12's.  It'll be a ton of fun.  I know of a few 383's out there with this same cam, about the same compression(or a hair less) and factory ported iron heads(which wont out do your darts) running 12.50's in 3800lb cars.

With your lighter camaro and better heads....Id settle for nothing less than a 12.40 pass out of this motor.

One question....which valve spring did you use?  Lunati had some issues where their valve spring reccomendation on the cam card didnt match the website.

Did you use the single spring with 108lbs on the seat?  I am not a fan of this spring.  It doesnt belong with this cam.  Let me know if it struggles to make rpm.  The cam should be able to go north of 6000rpm in a 383.  If it doesnt...its the springs

the are the pro 1 platinum . number on summit is DRT-11321111P.
the lunati cam is a voodoo LUN-60101LK.

I bought these parts to be on the best performance between 2,200 - 6,500 rpm.

.. The heads and carburetor may or may not match the cam, depending on cam spec.s...

.. The cam number you gave and the lift numbers you gave don't match, can you correct that? Which is correct?

.. HP about 350 - 500 HP and torque about 450 - 500 lb.-ft. depending on the corrected numbers above...

.. That big 233/241 cam and 200cc heads should have you in the 450-500 range...
