5.7 vs 5.3

[OBS ROCK]

Yeah 6.0 be would be great, but you asked about 5.3 vs 350, but if you can def. go with 6.0!

Yeah if I find a truck i like with a 6L i will prob buy it. But I still like the obs looks and I havent had any problems with the two obs my family has.

Ok fellas. Time to gimme some schooling. Isn't the 6L the 366 engine Chevy has been using in the bigger trucks for a very long time now?

 

[Z Fury]

It is. It came out about the same time as the 5.3L V8, as part of the LS engine line.

 

[Sully]

and being part of the LS series, it can be made into a friggin monster pretty quick and easy like

No, the 6.0L LS series motor and and the 366 big block are worlds apart. The 6.0L (LQ4, LQ9, LS2, et al.) is based on the same architecture as the LS1 that debuted in the Corvette in 96, while the 366 shares its roots with the original 396 that came out with the 65 Corvette. The 366 was a medium to heavy duty truck motor with a small bore and long stroke for low end torque, while the 6.0L motors are larger bore and relatively short stroke, made for torque and horsepower. The 366 is a boatanchor, the 6.0L can be a screamer with minor mods.

also, the 366 is a Tall Deck Big block, 396 is a Standard deck.

366 is a boat anchor, worst flowing heads ever produced for a BBC, and all it has is torque, not very practical.

On a good note, the 366 did come with a forged crank and was the same 3.76" stroke as the 396 and 427, and are/were sought after as a cheap source for a solid bottom end.
