Chevy has had it going on with the V8 since it's birth in 1955? It's been the same block since then, with only small improvements along the way. IE, vortec (reverse cooling which gained hp) and how many types and configurations has Ford, Dodge and any other v8 out there has done through the years. The Chevy V8 is the best and only V8 to ever own. Look at the stats on the 2007 Dodge Viper and corvette Co6 stats! A 400 ci stomped the V10's ass! Served it on a platter! So, I agree on the why do you need all the extra cams, timing, and crap to get a "new" v8 for Toyota and such, when Chevy has proved that simpler is better.
My dad had bought a '77 chevy 3/4 ton 2wd p/u, new off the lot and drove it almost 400,000 miles with only one new water pump, and one set of valve cover gaskets in it's life. And when he traded it off, which I begged him to give it to me, it still had less than 7% compression loss on the motor. And all the cylinders were within 3 psi difference. All he did was change the oil every 2500 miles on the dot, never over that. And never mistreated it in any way. After 60,000 miles the motor had "sealed up" which means the motor had basically quit wearing on any parts. Which is rare but has been known to do, especially if you talk to the old engine builders out there. The motor oil would drain out like it was being poured out of the bottle. Just clear and clean. And this was on Pennzoil too! Back when Penz was crap! So, to prove that it's not oil, it's the changing and the way you drive the motor. That's why I believe in nothing but toyota and chevy! I'll never own a ford or anything else.
