418 Stroker options....
I currently have my 340 in the machine shop which should be home soon
I had to go .040 on my block as well.
I got my kit from these guys.

I went with the forged crank and connecting rods from molnar tech
i also got dished pistons from icon in the kit to lower my compression ratio so i could use pump gas (89 octane)
Call campbell and they will set you up. I believe i only paid $2100 for the stroker kit.
The pistons were 360 pistons but +.08
my machine shop thought i paid double the amount for the crank and rods because of the quality and they are very hard to impress.
after the stroker kit i went very extreme and probably did not need to for a street car but i wont have to worry about power
