I've been looking at going with a completely different engine with carb as I've been doing a lot more mud and my stock 350 w/ tbi just does not have the power to turn the tires in this Virginia Red Clay. I would build up the FI but do to the cost and everyone I know of that has tried it has had issues so I'm gonna go carb. So the question. Should I see a decent power increase just by going to a carb and putting in a beefier cam? Most of the guys in my club seem to think just ditching the FI and putting in a larger cam will gain me decent power for not as much money as going with a completely different engine. Are all of the other parts on the TBI model 350's carb compatible (minus the intake manifold)? I also know a new fuel pump will need to be used. Can I use a Cam from an older model 350 or do I still need one specified for TBI? I'm assuming the specify TBI just for the mildness of the Cam since it is computer controlled. Any thoughts?
