yeah Rick D added the T1 crank to a Masi engine and pushed 440 WHP years ago without a problem. And not tuned right with grounding the injectors.
But out right, stock, the T1 late version is good for 270 with a 2.2 though and a good tune and the ability for the computer to pulling timing and boost.
The T1 2.5 and the 84-85 T1 2.2's are different and much much stronger.
Blocks are built to handle twist from the crank, with a steel crank less block strength is needed, like the early Mopar V8s. They added the steel cranks and internal balancing and the weaker block was fine. Then they made all cast cranks and the later blocks are a lot stronger. The Common block was designed for a cast 2.5 crank, so a steel 2.2 common block is the best of both worlds.
But really, for the majority out there the old block and crank is plenty strong enough. Then adding a steel crank to the early block is good for way more power than most anyone see's anyway.
I can't say I haven't bent the LW rods though lol
