Latest, greatest engine is Old School

[BillGrissom]

Got an e-mail from GM Performance promoting their new LSX 454 R crate engine, which they expect to dominate the tracks (how did they get my name?). Not a racer, just daily driver, but thought many of the latest design features are interesting to older Mopar fans:

we're excited about ... a shaft-mounted rocker arm system, and mechanical solid valve lifters. ... heavy-duty push rods

Sounds like a 273 or 340 TA, other than the roller lifters, but one can add to our old engines. They even use the after-market tie-bar type (big bucks).

The crate engine ships with a 0.700" valve-lift cam, and single-plane carburetor-type manifold so probably won't idle, but needed to get 720+ horsepower.

You probably have experiences like me where family and "tourists" continually question you about running crappy obsolete engines. This provides come-back ammo. Newer engines do have improvements in ignition and fuel (not race engines), but those can be retro-fitted to older engines. Two valves, pushrods, and in-block cams are still around. Indeed, my Chrysler 3.8L has those and is the "top-line" engine choice.

You should have sent them an email back telling them shove that pos up their arse.
Then ask them if they came up with some rods that don't snap in half.
GM=GARBAGE MOBILE.

The LSX 454 crate motor is a modern pushrod V8 that benefits from all the development GM has done on there LS series engines, other than displacement it has nothing in common with the muscle car area big block of that displacement. Nothing obsolete about that motor.

You should've sent them one back and told them that... "Thanks but I already have an old Chrysler engine with all that stuff, and it's a street engine"

Costs around 20 thousand and at only 668 pounds and 720 hp, for a GM person who has the money seems pretty decent.

Thanks, but I already have an backyard 360 which puts out 1/3 the horsepower, is a 100 pounds lighter and $19,000. cheaper and can run on pump gas while probably getting the same gas mileage.
