You can, but the stock program on the ECM will not be able to compensate for the larger cam. As matter of fact, the stock cam in the 4.3 vortec is large and was cut to give you the lower end torque that give the 4.3 pulling power off the start.
The larger the cam will cause you to bring the power band on your mid to top end and your going to suffer on the lower end of your RPM. Also take not that the CFM flow on the heads are limited so your going to have to match the cam with your CFM flow on the vortec heads.
It can be done with a custom chip for your larger cam and a higher stall converter for your transmission.
Keep us posted on your project.
