Damn... there is a tsb about checking the crank bolt torque, dont remember the exact reason behind it at the moment, but havent seen one come off like that yet!!!

 

5.3L with a Lysholm 2300, Kooks 1 7/8" with uncatted wye and a 3.5" MBRP Stainless Catback...if I have to put in a crank I may aswell forge it up...

 

So I need to hear some good advice...3500k budget...like between 500 and 600 rwhp. I have a 3.25" and 3.65" pulley now.

 

I also am a tech...just never even noticed a leak or a single noise so now not pinning bumped my timeline lol. So I have a shop and full box to do the work and base build - I also get 10% over cost on Delco/GM and the wholesale on a 3rd party performance shop.

 

Ok nvm the tsb... haha didnt know about the blower!!

 

I should have pinned...just cost me a crank 18 months early lol I wasnt planning on forging the internals just yet. Lol

 

Whats the saying? Everything happens for a reason!!! If i ever have to replace a crank i am going to stroke whichever engine it is..

 

Pull it and slam another oem crank in it if you're not ready for a full build yet. Probably less than $500 for parts and a machine shop to balance it. Have them cut a keyway while it's there.

 

If the goal is less than 700whp, I agree with Slvrram. The stock parts will handle the 500-600hp goal you had talked about. New crank, pin it and do some burnouts.
