Re: bad cat??

yes a bad catalytic converter can stop your truck from starting. 460's are pretty loud with no exhaust.

Re: bad cat??

If you have the proper tools or know someone who does you can 'gut the cat'. Which is taking the crap out of the cat and then reinstalling it - or a straight pipe until your next emissions check is due will be the way to go so you can save up some $ for a new cat. Inside it's mostly a honeycomb mesh that absorbs particles to reduce tail pipe emissions.

Re: bad cat??

perhaps you should check if the timing is still correct... if you have lots of miles on the motor, the timing chain may be worn and loose . This causes the chain to skip over a tooth or two and the timing sprockets no longer align ... lack of power and almost impossible to keep running at low speeds .... giving backfires thru the intake and eventually skipping enough teeth to bend the valves as they now contact the pistons and a no start condition.
