340 Stroker Build Need LOTS of Advice

Jegs sell a nice forged and balanced rotating assembly to go from 340 to 416
Costs just a little over 2k complete
Part number is 1-48015B1
Comes to about 10 to 10.5 compression with eddies. uses dished forged slugs
Pretty much same kit i have in a 418 but my pistons are flattops. Wanted more compression than you are wanting for just street use.
This will more than give you a grin when you hit the loud pedal
