FS: Complete Forged 346" Shortblock Selling for $1400 (add 3% for paypal) plus shipping. I can ship it freight in a small LSx engine crate for a very low cost due to small size and lightweight. I would estimate shipping to be $125-$200 most places.
Please do not reply or PM any lower offers in anyway. I am not looking for any trades. If it does not sell for the above price I will keep it on the shelf for another project etc...
Ive got a new 408" shortblock that I just finished up for my wifes car...I sold off the top end of the motor (fast 92/92, PRC heads, cam etc) so im selling the complete forged 346" shortblock now.
Its in great running condition guaranteed. It has a total of approx 4200 miles total on it. Motor has never given me any problems runs strong. Leakdown and compression before I removed the PRC CNC heads was perfect. No nitrous/poweradders ever used on it. Comes with no cam/timingchain/oil pump/heads/lifters/oil pan etc. This is a normal bare shortblock.

who did the machine work/assembly?
just curious, what numbers did it put down with the ls6 stage one/5.3 stage 2.5 heads? (not sure which you had on that motor, just going from your other post) looked like a small cam too

You can calculate compression ratio easily with this depending on your head gasket/head cc choice.

You could range from 9.3:1 to 11.5:1 depending on head choice (ranging from 58cc to 72cc and thin to thick head gaskets)

I have all my machine work and shortblocks done by Watkins Racing Engines. They are the designated shop for all the LSx based winston west/circle track spec (busch series/nascar type motors) as well. Their work is top notch.
I have made up to 483 rwhp on 346" shortblocks /w PRC ls6 & stg 2.5 5.3l heads on identical shortblocks with a solid/perfect combo.
We've also made 800 rwhp on exact same shortblock several times with forced inductions (blown/turbo setups).
Ive never broken a stock rod with good bolts at any horsepower level with a rpm rev limiter set to 6800...rpm is the only thing that kills them.
