Thank you for the fuel filter trick.
The camshaft is: Comp Cam: 11-318-4. I looked for a OEM one, the real L-37 one, could not find any reliable info on anything, so I used what I had.
I dynoed it, 437 HP at 5250.
I have a short video of the motor on the dyno, but I cannot post it, I tried but it doesn't work.
