How do you get 421 ? If you go to a 4" stroke on an Ls2 , it becomes a 402. Are you thinking of sleeving an LS2?
Anymore than a 4" stroke is not recommended with FI on this block.
But you should make up to 900+ on a stock stroke

As leadfootlarry stated. How did you get your 417. I'm just looking at different options. I was going to go with the 402 but my tuner said we can do the 421 for the same price. But if it's not recommended I'll just stick with the 402. Thanks for the help guys.
