Honestly I think a fair price point would be around 6k. And I don’t like the fact that their 700hp block isn’t keyed or pinned.
6k with cams and head work? That would be steal IMO. Not to mention like people pointed out the turn around.
And Freek has shown you dont need keys and pins if you do it right. Not that Im near 700, but Im not worried about any thing (no keys or pins) at mid 500s. Yeah piece of mind, but thats all they add
I think like 8 of the top ten fastest MazdaSpeeds records were set on friction washers so yeah, assemble it right and you're good to go.
