A Carl Crank Port Job.

[bigdanracer]

I have been reading here and there about Carl Crank's hot port jobs. What are the details of the pluses and minuses of this modification and where can I get the specs?
Thanks, Dan

The Carl Cranke port specs for the 250s can be found in the Fall 2000 edition of your POG newsletter.  HR

Hi. Dan here. How can I get a past copy of the 2000 fall edition of the POG News letter and the article on the porting specs ?  I am a fairly new member.
Thanks, Dan.
