The "Indestructible" Slant 6

weak rods that propel many race cars (NA and BOOST) into the 10's, 11's, 12's...etc

being yours is a 77 its a cast crank so i dont know about the rods but non cast crank motors have forged crank and rods. you got the bad end of the stick for sure but how many miles are on that engine?
