    whats up with the high prices of cranks? ive looked in jegs and summit and there both really high priced. maybe its just me but its outrageous. im going to buy a BB from a buddy and it has a low end knock, so its 450 with the bad crank. anybody know of a cheap place to pick one up? or is it worth getting a used one? /forums/images/graemlins/truck.gif

    it all depends on what you plan on doing as far as a motor Rebuild. An Eagle 4340 Crank is a great buy for the money. a cast crank for a motor under 400 hp. is fine

    I usually go to swap meets when looking for blocks,heads and cranks--but you have to be careful not to buy something that has been reworked incorrectly.I went to one at a local racetrack with a friend last year,he scored a freshly reground 427 steel crank with rods for 150 bucks--much less than turning his old one. You might also try calling some local automotive machine shops in your area--many times they do work on someones crank or even a whole motor rebuild,and the customer either dissapears or gives up on his dreams when real life comes calling,and has to bail out.I've seen guys buy a complete rebulit big block at one machine shop, a guy stiffed them and never came back--they sold him the engine for 600 bucks,only 100 more than their cost to rebuild it.This happens more often than you think--its worth calling around,even if they dont have anything there,the machinists often know someone who does--Good luck!. /forums/images/graemlins/crazy.gif
