I can measure when I get home, but the block to frame is pretty short, 12" or so, the battery to frame is 2-3 feet iirc.
While solid grounds are very important, the pos cables from the battery to the solenoid and the solenoid to starter need to be in tip-top shape as they bear the most current.

Same, mine starts quicker and quieter than my 2012 Honda.

Thanks man, ill check the positive cables when i go out there. Do you think a 18" Block to chassis and 48" battery to block will be sufficient? or would those be too long?

You'll definitely have some slack. Not an issue unless you want that clean show look. Just route it so it won't get bounced into the fan!

Alright, this truck will eventually be a all out mud truck XD Looks arent that important to me, as long as it runs great, and will get me out of most situations i puit it into im good. Will do, going to probably end up zip-tieing it along the frame. Thanks Man!

Update:

Replaced the cable going from the battery to the block, wasnt able to see if there was a wire going from the block to the chassis so i put one on. But it is still doing the same thing. Just warrantied out the solenoid and was going to replace it along with a new solenoid to starter cable but it started pissing rain XD ill get those replaced by the end of the week.

The battery to the block (Ground) cable is a good start. The Positive cables are going to make the most improvement in your situation. If you have flaky electrical stuff when you drive the truck more we can talk grounds.

The Pos cables are the ones doing the heavy lifting with the current. Also remember to buy a wire brush and clean all the terminals that are corroded. New cables and solenoid should have this starting up nice. Starter pulling hard. Also remember that the cables and stuff new is great, but must have a good connection. Nice and tight on the bolts but not to the point were they will break.

Sparking means the current is trying to find an easier path to go to.

Take a video before and after the solenoid and positive cables.

Ill take one of my truck from inside the cab. Starts better than new.

I haven't had a carb in a long time but the second video sounds like you're not getting gas or air, need smell-o-vision. Last video sounds like something I could live with.
Also you battery is reversed from mine, it was freaking me out.
