Just wondering if when rebuilding an engine that runs on speed density like most of our trucks it can handle stroking the engine. I know from reading on here that cam options are limited because the computer relies on vacuum and bigger cams mean less vacuum.

My current engine is still running strong just like to research options before the need arises.

My 92 has the 351W in it. And if I were to come across a 351W roller motor then I might pick it up for future use.

I figure stroking a roller motor and a slightly bigger speed density friendly cam and slightly larger injectors should make some good torque and power, that is if stroking a speed density motor is possible

Stroking with SD is fine

 

Problems arise with SD when you exceed the limits of the stock calibration and that's not that hard to do, if the motor produces a smooth idle you can push the limits pretty good and get reasonably good results but once you're beyond what the stock injectors can supply it pretty much needs tuning so it gets complicated from there. If you were to build a 408 or some such it's possible it would run decently on a stock 460 computer with 24lb injectors or maybe a Lightning computer which is compatable with some tuners so there are a few options.
