I thought I had been involved in several discussions with members that are no longer here on the forum. I found one discussion that was started in Sept. 2008 regarding a joint 848 head porting and flow bench project with one member that was in Canada. I did some port work and flow bench testing to both the Stovebolt head and a GMC head for comparison. Results were posted but so far I can't find them because you can only search back 10 years, and those discussion predate that time.
No limits. One can search the entire database by removing the date range entirely. But if your search arguments aren't tight you may be limited by the number of posts in the result set:
