IMCA Stock Car Crankshaft

[dereksehi]

Does anybody know of a 4340 crankshaft for 350 chevy that does not have lightening holes in the second and third rod throws I am building an IMCA stock car engine tht has to run in an open street stock class every other night and want a little extra insurance above stock cast or cast steel.

cola/howards track smart or lunati sledgehammer. both have been discontinued though. i've heard of guys buying standard weight 4340 cranks with all 4 holes drilled and filling in the center 2 holes by having plugs installed and tig welding
