Exactly what I need to have done. 5.400 302 rods fit the 2.9 crank with the correct bearing, but they need to have 0.002 shaved off the sides of the big end.

The small end needs much more cut from the sides of them, likely 0.25+ and a set of bushings need to be made or purchased to size the 0.912 rods to the 0.866 pins.
Damn shame the local machinist is getting so hard to find... because that doesn't seem like a far fetched request. There is someone for that job. I texted my old business partner to see if he still talks to Scott... I would trust him with my stuff... I will let you know and if possible... I will set you up so you can talk to him.

So... it seems Scott and his dads machine shop closed up about 5 years ago. Scott now sells insurance with no access to any kind of machine shop tooling. I still think there is someone that would do this...

I am sure the 2.9's would take 6-8 psi of boost on stock internals with a good tune and added fuel. My 3.0 took almost 20 psi for 20K abused miles, this was on a motor with almost 100k, it finally stretched a rod bolt & wiped out 3 of the 6 rods & added ventilation holes in the pan in several spots. The pistons all looked great other than damage from the loose rod pieces.

I know I’m posting 11 years in the future, but if you got pics of how you mounted that turbo, I’d like to see them lol. Boosting my 2.9 and looks like I’ll have to fab most of the manifold.
