Need 340 Build Advice

Speed-O-Motive offers a kit for the 416. Hughes Engines, Hensley Performance, tons upon tons upon tons offer it. Only problem that i have seen is that most only come with a cast crank so it will only be good up to 550-600 hp. I dont know for sure but some manufactures will work with you and if they offer a 4340 steel or any other kind of forged crank they might put it in the 416 kit. I dunno for sure but you can try it. The cost of a forged 4.00 inch crank will probably be in the 800 dollar range. You get what u pay for so dont worry. Here is a lil hint I learned. 4340 steel is just as light as aluminum but it is also stronger. 5190 (correct me if i am wrong) isnt as strong or as light as 4340 but hey it is at least forged. Just depends on how much power you want to make. See ya later!
