[nissanmini97]

i seen that glacier is doing a head swap from sohc to dohc in a 240 but im wonderin can it foresurely be done in a 97 pickup with the sohc motor and if so what do i need to make it happen other than the head....and what are the advantages to doin this...

if it can be done on a 240block, then it can be done on a truck block. only difference I can think of is that the car blocks have a crank girdle and they have that ring that you bolt the starter through.
