Advice needed on building a forged stroker
Im looking into building a motor and would like to hear everyones opinions on which route to go. Should I take the ls2 thats in the car and buy a rotating assembly and drop it in or is it more cost efficient to buy a short block. And of coarse theres the heads Im looking at the afr's but which ones 205's or 225's or whats everyones thoughts on that. Oh and yeah I guess I should mention it'll be supercharged not shure on the boost level yet but would like to drop the compression ratio and add more boost. Theres lots of decisions to make and I would like to get the ball rolling soon!

You first need to decide on what your HP goals are? You may be able to achieve them with your current LS2.
Then I would recommend reviewing some of the current crate engines like the ones Scoggin Dickey offers.
I would also consider the new Chevy L92 heads verses the AFR. The L92 heads are $175 bare and will flow as well as most aftermarket heads. You can add some good quality solid stem valves, aftermarket springs, titanium retainers, and spend half the price as the aftermarket heads.

Bought a forged 402 stroker short block from Texas Speed. Added a crane cam. Put back my AFR225 heads, dynatech headers and procharger D1SC. Using the PC 4.75 pulley and 3lbs of boost made 560/506rw. Changing to a 4.25 pulley and increasing the boost to near 10lbs tomorrow, will post the new results.
The important thing is to work with a reputable tuner and decide were you want to be when you're done building the motor.

If you were to reuse your block then you have to wait while it gets machined and assembled. Having another engine built pretty much brings you down to how quickly the engine can be swapped out. So you have to way the cost versus down time... what's worth more to you?

From a pure HP standpoint, an iron block like the LSX is superior. Plus, the LSX allows larger bore and stroke sizes. But, we don't race blocks. We race cars with blocks in them and 100-150 pounds is a definite advantage, especially if you run road race tracks.
The Merlin folks have a new LS aluminum block that looks very nice.
You can also use the LS3 or LS7 Chevy alum blocks as they have larger bores than the LS2.
