Most advanced? Get real. OHV engines with 2-valve heads went out in the early '80s. Dual overhead cams, 4-valve cylinder heads, variable valve timing; now THAT is state of the art.
I wont say that GM's engines arent dependable, but longest lasting trucks on the road? Im not buying it. I know way too many people with GM trucks who are replacing waterpumps and alternators once a year and who go through intake gaskets like they are going out of style.
GM's truck last a good 150,000 miles before major stuff starts to fail, but I know many people with older Toyotas that have 300,000-400,000 miles on them and have had no major parts fail.
I know you are a GM guy and youd like to believe that pushrod motors can still compete, but the fact is that they are inferior. Overhead cams engines are much more efficient (you get more power per cubic inch with overhead cams) than pushrod engines and because OHC engines have fewer moving parts you have less of a chance of a mechanical failure with the engine.
I guess you mised the c6 z06. Surely that car cant compete. Or maybe, maybe the c5r thats been destroying the Le Mans series...running against superior motors, as you would call it.

hmm all those wins on a stupid pushrod motor. No way couldnt be. Hello, its not 1980 anymore, and this isnt your daddies small block. I guess its inferior.
As for your intake gasket quote....well thats a flat out lie. Nothing more nothing less. 3rd gen small block motors run nothing like the 1st or even second gen motors. They dont have an intake gasket. They have 8 seperate rubber gaskets that seals the manifold to the heads intake ports only. No coolant flows through the intake and there is no seal to blow out. So thats a lie on your part. Thank you though. But I guess toyota never needs a new water pump or alternator....which would seem funny, cause most auto part stores carry them for all companies as they are usually in high demand.
"Overhead cams engines are much more efficient (you get more power per cubic inch with overhead cams) than pushrod engines and because OHC engines have fewer moving parts you have less of a chance of a mechanical failure with the engine."
There may be less moving parts, but the chance for catastrophic engine failure are way higher on OHC motors. I over reved the motor on my 98 (went from 4th to 2nd gear on highway) and I limped the car home. Then I checked the pushrods and found 4 bent ones. Changed them out the motor was good as new again. If I did that to a ohc motor it woud of been bye bye motor. As for your more power from OHC well sure it may squeak an extra hp by not having pushrods, but than again its got a loooonnng timing chain to make up for it, and when it comes down to it Im pretty sure CR, displacement, and cam specs determine hp more than ohc or pushrods, but than again what would chevy know, I mean they only beat every car but 1 at the nuremberg track in Germany....for a fraction of the cost of its competitors. you can look that up if you like, I believe R&T did that article.
again its not 1980. Here you might learn something.
