Probably looking at around 440-450whp on a Mustang Dyno after cams. Everything seems to be fine down there (knock on wood).

How far are you planning to rev it? ARP rod bolts might be a good safety net. Also, I don't know if those pistons are heavier or lighter than stock.

I revved to 8k on the first tune, but brought it down just a touch to 7800 now. I don't want to push those rod bolts. Previous owner replaced rod bearings, but not rod bolts about 5k miles ago.

I'd say stay around 400 hp with these rods. Actually not a bad combination, long engine life, can run on native fuel.

I thought the factory rods on the EVo 8-9 4G63 were forged from the factory , just like the crank is?
