which ofna engine? got a part number you need?
which two engine are you trying to interchange parts with?
i read a reply on the ofna board made by a guy who owns a hobby shop. this is his response. to the topic on difference between 8port and 8port race.
"the exaCT differece are
coated case
new head
new crank with really big port and turbo scalop.
new beefy rod
p/s are the same
new bearings for new crank
now you can't put a pull start on it. the hole for the drive pin is way to big. looks to be drill for a weight savings.
motor is real sweet. 2.7 no way.
later
aldo"
i dont know if those are the two engines your working with. add some more info and i can try and help more
Mine is the black head hyper that is in a dominator. Sorry for the confusion guys, but I'm a transfer from electrics, :bow:
Thanks for the help and links also.
