Burnt shifter cable today

well i was lucky to get the car home, but it would appear that i have burnt the shifter cable all to **** against the TTI headers. 71 Big block duster, 727 trans B&M shifter. Debating whether or not to order the longer cable? is there a particular route or secret to this? I had clamped the cable away from the exhaust with a bracket and bolt from the oil pan, i guess that didnt work.
Did the same darn thing Fisher, went out for a jaunt, parked in the driveway with it shut off for 10 minutes, came back out to move into garage and shifter would barely move. I have small block with 1 7/8 TTI's. I do have a mini starter and the B and M shifter came with a pretty long cable. I got a shorter cable from Summit and was able to route it better. I also put some heat resistant sheathing around the cable. I hear you, it is a trick. The second time I probably spent 5 hours getting everything correct. I think I even made a small solid bracket to hold it off of the headers. Good Luck!
