383 to 438

[Sixtynine_Bird]

Hi guys,
as you know, we are pulling appart our poor little bird for a complete resto!
And for the engine we'd like to upgrade it with a little stroker from 440 source. We'd like to reach roughly 500-550 horses could be grate for fun!
So do you think it is easy to get 500hp with a 438 stroker?

Depends on how much cam you care to put up with on the street. I think 450 is possible with a very street friendly cam. 500 might make it a little rough around the edges.

The heads will be very important to get right to get your power level
