American Car noob question

  1. Eh. I'm much more of a small block person.
  2. Thank you Kind sir.
  3. i was under the impression that the Chevelle SS had an option of the LS-6 or the LS-5, the LS-6 being the 450hp one
  4. And your impression would be correct.
  5. dont forget all the L88's, L96's, and others
  6. You can't be serious. Who in their right mind chooses a 400 HP 350 cid motor over a 500 HP 454 cid motor?
  7. someone thats handling oriented?
  8. A person whose driving consists mostly of 200 mile trips back and forth from school.


  9. The LS series is an evolution of the LT family but is all-aluminum and has 6-bolt mains. The LS engine has been the sole powerplant of the Chevrolet Corvette, and has also been used in the Pontiac GTO, the Cadillac CTS V-series, the Holden Commodore and Monaro since 1999 and the late Camaro/Firebird V8 models.

    The Generation III small-blocks replaced the LT family in 1997. These shared the same rough displacement and bore spacing (4.4 in) as their cast iron predecessors but almost everything else was changed. The bore was reduced to 3.9 in and the stroke longer at 3.62 in for greater torque. The block was cast from aluminum (for cars) instead of iron and had a new intake and injection technology and coil-on-plug ignition. The traditional five-bolt pentagonal cylinder head pattern was replaced with a square four-bolt design, and the pistons are flat instead of domed. Even the cylinder firing order was changed.

    Generation IV
    Hot on the heels of the Generation III was Generation IV. These big-bore engines are some of the largest small-blocks yet, and will quickly replace the previous generation. Displacement ranges up to 7.0 L and output to 505 hp (373 kW). Generation IV will later feature displacement on demand, a technology that allows one bank of cylinders to be deactivated. It will also offer variable cam phasing and 3-valve per cylinder designs, a novelty in a pushrod engine.


    Holden Special Vehicles is widely tipped to use the LS7 on its 2007 GTS.

    Chevrolet also had an experimental big-block engine named LS7 in the late 60's that were supposed to be in the 1970 Corvette, but it never materialized. Some LS7 heads were sold as an aftermarket product in 1971 and 1972 though.
  10. the two motors he is refuring to are the ls2(400 hp 6.0 liter) and the ls7 (500 hp 7.0 liter) are both small blocks, so there isnt a drastic change in weight if any, so handeling would only be affected by the lack of rear traction the ls7 provides.
  11. No he is talking about the 454 LS-6 from the 60s. Which was a bigblock.

    And just FYI to anyone, the LS7 is physically the same size as the LS1, and about the same weight, if not lighter.
  12. Those are not the two motors I am referring to.
  13. I'm well aware of the actual CID of the LSI, Mr. Statistic.
  14. lol @ ferrarista and you guys.
  15. depends on the car.
