I have a 350 Rancher with after market 25 in tires. I would like to put in a litter hotter cam for a quicker response and a little more power. What do you Gurus suggest I get without having to do any other engine mods? Looking for what we call in the 2 wheel road bike as a mid range cam.

 

Though I don't have personal experience with them, I've heard good things about hotcam's mudbuster. Does not require other engine mods. Pretty good boost through mid-range. Looks kind of like the curve of what V8 folks would call an RV cam.

I don't know if they make anything for your application, though.

Looks like Webcam offers one for the 350 that is supposed to increase power across the whole RPM range, apparently a weld up, so you have to send your stock cam in or pay a core charge.
