Hesitation / Stumbling, runs rich at idle

Did Randy get an aftermarket camshaft cut for it? That is the whole program on how it's going to run.

Too much cam can be a stumbling block for hot rodders, especially on a V6.

Stock Grind 4.3 262 cu. in. V6 camshaft: (and that is stock for Throttle Body Injection engine)
Imagine a Carburated V6 camshaft is going to be ground differently.

Lift intake .350
Lift exhaust .385

Duration in. 262
Duration ex, 262

Would be interesting to hear what his 4.3 cam grind specs are, and how far up the rpm band it goes before making power?

He got the biggest cam that was offered in the 4.3's from the factory. It's a hydraulic roller and the engine he has was fuel injected from the factory.
