Atlas / Vortec 4200 T4 with divided single 50mm wastegate!

Not one person asked for this BUT I think this engine has not received the attention it deserves.

We have been working with @nivlac57 and @motionautotv. The 4200 Straight 6 from @generalmotors was released in a Blazer, but the ability for this engine to hold itself together at now over 700whp through an auto has been documented by Calvin over at the Nivlac57 YouTube Channel. We have designed this and tested on a number of chassis to allow easy fitment in LHD builds.

This has been designed to accept up to the larger frame @garrettmotion G45’s,  @precisionturbo 75's and 85's as well as @borgwarnerboosted S400's. Again we have machined the manifold to suit a @turbosmarthq 50mm wastegate, but can run a 60 if you cut the flange off (as the runner is designed to flow the 60).

Not for the weak...
Color: 1 pk
A bit tough to use. My blend has green peppercorns in it. The mill does dispense a finely ground powder but it takes some significant wrist action. I don't love this item which I find VERY "manual" though quieter than any motorized version. I wouldn't buy it again.

Loved it!

I loved it! The grinders look very elegant and work perfectly. The size is great, they’re easy to use, and the grinding is smooth. They also feel sturdy and good quality. Definitely recommend!

Nice grinders for the price
Model: 2 Pack Salt and Pepper Grinder
The grinders are working fine, though I have only used them for a couple of days. Their size is a little smaller than I would like for in kitchen cooking, but I got them knowing they will work better in a planned move with a smaller kitchen. Good size for a table. I'm happy with the clean, simple appearance and the quality so far. Just ordered a second set for white and mixed color peppercorns and will donate the sort of hodge podge assortment of grinders I currently use.

Love them
Model: 2 Pack Salt and Pepper Grinder
Love those. Good quality material and work very nicely. I like that I could set the size of the ground salt and pepper by myself, this was very useful.
