they list LR4 as the 4.8L V8, and the LM4 as the 5.3L V8, both used on the silverado.

they also state that the LS4 is what's used in the FWD impala and such.

if they are correct, then i believe the LR-LM-LS is where we are all getting confused, especially since LS2 is RWD and LS4 is FWD.

 

Ok, but it might be replaced with a SS-Z/28 or RS badge
Is there going to be one?
where it should be.
OK, I don't like it and will be taking it off regardless.
See number 1
Which should read 327 or if need be 325. 327 has heritage.
Last new Chevy I bought didn't have one. I have removed all others as a lot of people do.

Now that you mention it it may have been a phase-in, but if so I believe it was later in the model year rather than earlier. I'm relatively certain that 1970 was the first year that all 396s were 402s. All 396 Chevelles from 1965 to 1968 I know for sure are "real" 396s and I believe that carries through most of 1969.

 

I guess the question is how much can you change an engine before it becomes a new model. The LS4 has a different oiling system than the 5300 to protect it under prolonged lateral g's, and wouldn't work for RWD. The intake comes in from the back of the engine (over top of the oil pressure sender ), and woudn't work for RWD. The accessory drive and water pump are a more tortured design in order to save length. In short, you'd have to make so many mods to an LS4 to optimize it for longitudinal use that you'd basically be ending up back where the 5300 started.

 

The actual displacement of the engine rounds to 325 ci.

There's nothing wrong with using this displacement as a badge instead of the old 327 (which even outside of legal issues, I don't know why anyone would want to use).

A Chevrolet 325 would have the same ring as Ford's 5.0, Pontiac's T/A 6.6, or the LT1 without having to go to the past.


BTW:
1. I think Camaro badges outside should be scarce. Ford has NO Mustang badges on their pony car.

2. Exterior engine ID tends to make engines famous. SS396 was so popular that when displacement changed, GM kept the engine size on it's badges strictly as a marketing decision. No one calls the Mustang engine the "4.6", but "5.0" made it into a few songs and became famous. Badging works. Look at "Hemi".

3. 327, while an important engine, was never really a top dog or track terror. Chevy's 350 powered vehicles for 30 years compared to the very short (7 years) reign of the 327. Pontiac had a 326 filling the same duty. It's just that Chevy was limited in engine size on most of their cars.

 

327 did have the highest gross hp of any small block though

 

the LS7 427 is larger than the old big block 427s.
BBC = 4.25 bore x 3.75 stroke = 425.587
LS7 = 4.125 bore x 4 stroke = 427.649

im all for a 327 badge on the side but personally i'd rather see a 427 badge

 

The Viper has 505 written right across its air intake.

I like the idea of seeing the displacement in cubic inches written on the valve covers of the engine or something like that. I believe Lingenfelter does that on many of their c6s. Gives it an American feel to it. I don't think the Camaro needs any more badges on it than the particular model it is though (i.e. z28,SS etc.)

 

I like the idea of a Cubic Inches badge somewhere. Younger generations dont know that much about cubic inches, but cubic inches really reasonate with the older generation and I think it might be making a come back. Whenever older people see my car and see that its a Z28, they ALWAYS ask, "Does it have the 350 in it?" Im almost positive that they have/had no idea what engine offerings were in 4th Gen F-Bodys, but because of the popularity of the 1st gen cars, they know what engines were in them and they assume that the some of the same engines are still in the car. So Cubic Inches gives some good heritage to the engines in the new Camaro. I think it would be a great idea to put some CI bades on the car, and if possible, try to make em the same as the old engines.

 

cubic centi-what? this is america. i agree with the use of cubic inch numbers.

in addition, i think the use of cubic inches will add to the 'mystique' of the whole muscle car thing to those newbies.

besides, when i talk or think cars nowadays i'm tired of having to convert liters to cid all the time

 

I am part of the younger generation, and I think it would be a great idea to have cubic inches written somewhere on the engine or something like that. I love the way the Viper engine does that.

 

You know something? Badges actually suck IMO. I was looking at my 67 Camaro today. Behind the front wheels on the front fenders I have:


I was imagining how clean it would look with just "camaro" there. Maybe its my love for stealthy Q-ships that causes me to want to be a little secretive of what's under the hood. I mean, shouldn't a bow-tie and "CAMARO" be enough?

 

Mark me up as one of those who would think a 327 badge would be "cool". With as much as the 5th Gen uses 1st Gen styling, the "327" badge would complete the look I think.

My 66 Vette is in pieces, but as soon as I get it put back together, I'll have to get a dyno run to post some numbers for a 327 .

 

The BBC stroke is supposed to be 3.766" which gives 427.4 cid.

Guy, true, the 327 engine really wasn't that big a deal back then, but today most people see things through rose colored glasses. The "327" would work with the heritage of the car.

I still say that it would be awesome if GM were to use the existing bores and strokes and change them around a bit for new displacements. 4.00" bore + 3.268" stroke (from 4.8L) gives 328.5 cid. That would work and be a better performance engine than the current 5.3L truck engine because the larger bore would allow better breathing.

And if everybody wants the "350" back so much, then put that same short throw crank in the 4.125" bore block and get 349.3cid.
