I agree...
1-Ton has it right--you put the purple wire on the wrong stud on the solenoid..just swap it to the innermost one nearest the block like he suggested,and it will likely solve your problem..it wont hurt the HEI at all,don't worry about that--no harm done!..
I have switched all my GM trucks red wires with the fusible links at the solenoid too ,like Pauly said--back to the battery positive terminal,just like the way GM used too in the 72 and older trucks--why the ever moved them to the solenoid is beyond me--90% of all wiring troubles in the 73 up trucks is due to those wires melting inside the "conduit" pipe bolted to the bellhousing,only an inch from the hot exhaust manifiold..

if the fuse links burn up for whatever reason,now you need to pull the starter to fix them!

DUH!!..anbd the stud holding the battery cable on would always crack the plastic cap on the solenoid..
I found on my 79 C10 those wires were too short to reach the battery--so I took another identical harness from a boneyard truck,and used an old junk ford style solenoid on the firewall ,just as a "junction block" to bolt the two ring connectors together,so I wouln't have to splice or solder them-(solenoid doesn't do anything,I just used it because it had an isulated base,and I was too cheap to buy a junction block)-now I have 2 pairs of fusible links!--double protection..I've run it that way 2 years with no trouble at all..same with all the other trucks I had..sometimes the "old" way os the better way..
