I have a aluminum 5.3 on a stand right now that i am gonna put in my 07 silverado. The cylinder wall is huge, can be stroked to a 398 with stock sleeves. These aluminum 5.3 's only came in SSR etc. special edition truck stuff. They came with ls-6 style heads and a ls-6 cam. Before I put the 408 in my Iroc, I had a 6 litre block. Ran a 10.9 on a stock 6.0 litre lq-9 with 150 shot
complete callies 408 using 6 litre Iron block= 3900bux for shortblock
