We got to try out this test stand yesterday. A friend bought a used gm crate 350hp 350 a while back. We put it on the stand yesterday and fired it up. This thing is great and a lot of fun for a bunch of guys on a saturday in the garage.
A few minor glitches I have to correct yet. My throttle linkage design was a bit flawed, I have to tweak that a bit. The electric fuel pump leaked more fuel than it pumped so we just used the mechanical pump. I am going to move the electric fan to the front of the rad for a bit more clearance as another friend wants to fire up a blown 468 BBC on it. I also have another request for someone to fire up a fresh 350 in a couple of weeks. I should have all the minor bugs worked out of the stand by the time I have my 496 ready to run. I will try a post a couple pics from yesterday
