Yes i got it is will shoot you a PM shortly!
True on the variety of turbos but the frames start growing after the 6767's which is not to big of deal but the piping grows also I still have the 7075's sitting in the back of my head!

Should I go with the larger .96 housing with the 6767's ?
The beauty of a 4500 stall that is designed for 1000whp is that it drives like a 3000 stall off boost

I think a thread with people posting photos of turbos for physical size comparison would be good.
I'd think your small cover 6767's would be similar to the S200's in these photos.
The larger 300's, same as the bigger 7xmm units. As you can see, they really arent that bad at all though
And the 67's and larger can be had in the large cover too, and would be more efficient with that

Bring this back to life Jose finally got back to me and he recommended BW Billet ETR
S300 66's which i think have a 73MM turbine. They are priced right anyone using a pair of those and know what kind of power they will put out?
I was set on using BB turbos but been told that the BW journals would be just fine and spool very well on a 427 but i read everyone going Ball bearing!

Everyone in the 4cyl world might be ballbearing, and yes where budget permits BB is always a better option.
But it's a 427, it will never be short of power off boost, and assuming it's mostly straight line with an auto, transient response is hardly an issue regardless.
