Yup, these are the facts ^^^^So heres the kicker... all stage 2's CANT handle that power. Theres core shift in many where the cylinders are thin and if they have been bored out this wouldnt be a good candidate and its best to get the cylinders sonic checked. The on center stuff especially the last iterations with all 4 bolt main caps or 4 bolt and 6 bolt main are better but, still should be checked. Another concern with the OFC stage stuff with the 3.8 is cracking between freeze plugs. Now the TA block is awesome but will need 1kish in machining work above and beyond purchase but will get it done without issue. Either way not cheap
Damm how many guys running tso and making close to 1500 hp? That’s super impressive. I didn’t think they made that much power. WowI know lots of the TSO guys with iron blocks are running well into the 1500hp range with there 88mm turbos.
They can handle the power, but at that level the lifespan of them is shortened.
My stage II 153 casting is well over 1000hp and it’s lived thru quite a bit of abuse.
As others have said, it’s more about the internals and the tune
