The rod ratio for the 4.8L is perfect for boost. The High RPM and High Boosted Torque translates into serious HP.
Well, I still think its true... Here's a quote taken from another forum on a stock bottom end turbo 5.3:
Skinnies 8.68 - YouTube
Oh and Skinnies RX7 made 855rwhp/1145rwtq on 24lbs. It's a single billet Precison 78mm, bone stock bottom including rod bolts, ring gap, and oil pump, GT2-3 cam, springs, and pushrods. That's through a glide, a 9", and some massively heavy 33" x ?20"? x 15 wheels with DOT street tires. Easily over 1000bhp.
These motors are plain sickness. It makes me laugh when I see a multi thousand dollar engine running 11s/12s/13s etc (been there, LOL).

Exactly! Just think if they took a few seconds and spec'd out a good cam. You can find a lot of power with the right combo. (not that they needed anymore)
Excellent write up thanks for sharing!
Was there a dyno graph by chance, I'd really like to see the TQ numbers and what rpm ranges they were working in. I'd like to see how much the shorter stroke would have on the low rpm torque production. I'm not a huge fan of high stalls, not what I'd like to drive daily.
Thanks again!
