512 stroker for the street??

A stroker makes a lot of sense if you're going to do a full rebuild. The cost is only slightly more to buy new parts than rebuild all the old parts. The bigger engine provides more torque and/or more power depending on how the build is put together. How far you go with the build just depends on the budget and the goals for the build. I have a recipe that I follow for performance stroker engines but the end result might be more expensive than what some people want to spend.
The motor was originally rebuilt in the mid 80's. The block was bored to .030, the cylinders have some taper so it will be honed to .040 to clean it up. The crank needs to be ground and polished and the rods need to be reconditioned so stroker seemed like the way to go. The iron heads need a complete rebuild so aluminum is the smarter way to go. Plus, who doesn't like the idea of having a big block stroker?
