I6 headers burning my cables
I have a 300 with a header n I keep burning the ground ( by the starter to the frame) and the starter cable any Idea on how to avoid the cable being burnt and can I ground the block anywhere else or does it have to ground from one of the starter bolts?

Welcome to the forum, music666!
Most 6 cylinder engines, from the factory, route the negative cable from the battery to the starter mounting bolt. About midway, there is a metal tab which bolts to the frame, thereby accomplishing grounding the frame and engine with 1 cable.
It is best to go straight to the starter, so the electrons can flow with the least resistance to the item [starter] which draws the most amperage. However, many V8s have the ground cable attaching to the engine block. You might look at getting a longer cable and reroute the cable along the fender liner [staying away from the header] to the starter bolt. Then, take a 2nd cable [20-24" long] and secure it to the same bolt on the starter and then attach the other end to the original frame bolt.
I would suggest getting 2 gauge cable rather than the original 4 gauge since the cable will be longer.

I would slip some of this over the wires.

IMO Route your negative cable to the engine block, then add a ground strap from block to transmission/bellhousing ... This not only allows you to reroute the melting wire, it provides the starter with a solid ground.
The ground strap between block and transmission/bellhousing is very important on a Ford IMO because the starter bolts to the Bellhousing with a plate between them!
