94 K1500 TBI / Vortec head swap - Cam question

[dispoejoe95]

If it was TBI Chips then you're probably better off getting someone else or tuning it yourself.

The GM cam looks like a decent piece for a towing application.

Going to Vortec heads will require timing changes as well. You'll probably run out of fuel on the top end requiring more pressure or larger injectors. It may be just OK with the current cam but the new one will probably make run lean.

ha...not dealing with TBI Chips. Haven't seen many favorable things about him. I figured timing would need to be adjusted in the tuning but are you referring to the base timing? I currently have it set at 0°.

No, he is referring to the timing tables in the .bin. The vortec heads like a lot of timing and will benefit from a change in the timing/advance curve. This requires tuning hardware/software(Tunerpro) or the services of a competent "tuner" preferably from this site if you choose that route.

As for cam choice, the cam Fast355 mentioned is similar in spec to one Ive ran, it pulls pretty hard, so something in that range should make you happy.
