opinions on 340 stroker kits

Hi,

if you use the 340 (with original 4.040" bore size) you will get more than 408 cui, usually around 414 or 416 cui with a 4" crank - just for information.

I´d stay away from cast eagle 4" cranks, noticed some broken ones here around this forum.

Material of crank / pistons is up to the task you have for the engine - my opinion is if it´s natural aspirated and below 6500 rpm then a cast crank, cast or hyper piston combo is fine. If you want to use nitrous and / or boost / high rpm (for example a strip only engine) i´d use a forged crank and forged pistons. It seems that the scat i-beams are a good value for the cost, i personally went with a scat kit (cast crank) with KB hypers - everything was ok, engine runs very strong.

But as i told before, keep future upgrades in mind.

Here on the board are some vendors (mrl engines, imm engines), i´m sure they can offer a good package that fit your needs.
