I don't know anything about turbo specs.
I was looking for a he351 turbo because it will bolt to my manifold, with some clocking of the turbo.
I did remove the tamper collar from the power screw,today
turned in the screw, just below run away > I hope....lol
installed the 3800 gov spring.
going to the track Tuesday night, to see the improvements.
looks like I'll run the 3.73 gear in the Dana.
looking for a 4.10 and down spool,
Have a extra 4.56 spool.
