400 to 451 stroker questions

I saw where 440 Source has an all forged kit for $2300 for a 512 stroker !!
Yeah they're all the same price. It's a good deal for good stuff. They claim there stuff is balanced but we had to do minor corrections to balance it perfect. A 512 will be good, it won't have to work very hard to make the power you want. You'll want atleast main studs and mainline honed .
