[V8] AC conversion Pressures

[Jason Wilkerson]

I converted my v8 to 134a.  It blows ok cold, but not quite enough.  I know that 134a isn't as efficient, but I thought it would be better than this.  I was wondering if anyone knows what the perfect pressure is for the A/C system On a 1990 v8 that has been converted?  Say at 70 deg amb?  Or, do you know the fill amount in terms of lbs for a converted system?  Thanks in advance.
