i need help to find out whether or not chevrolet ever place a 502c.i.d. engine in one of their cars. And what are some of the engine codes for the 305, 350, & 454. ex:454-LS6. this is for aproject and i would greaatly appreciate it if you would help.
thank yall

NO! chevy never put the 502 in a production vehicle. it was (i believe) originally designed as a boat motor. engine codes...454 = Ls-3,Ls-4,Ls-5. 305=LG4(305 w/ 4 barrel quadrajet) L69(305 h.o. 190 horse) and 350= L82(corvettes).. sorry, that is all i can thinkof right now, if i have any more i'll post them later.

does chevrolet still produce the 305?:confused:

does chevrolet still produce the 305? and what does the h.o. stand for?

I believe they phased out the 305 when the new ls-1 based engines came into production. H.O. = high output. it came in the malibu SS and Montecarlo SS and the ElCamino SS. don't waste ur time trying to hop them up too much, it'll cost about 2,200 dollars to make about 300 horsepower, while u can buy a 2 barrel 350 for about 400, re ring it and hone it out and make about 300 horse power and 350+ torque for about the same price.

Actually, the (Chevrolet) 305cid V8 is still in production. It's only offered in the Chevrolet Express/Chevy Van and GMC Savana full-sized vans.

Thanks for the insight, i did not know that.

Where can i get stock dyno charts fr some of thses engines?? cause id like to know how much h.p. and pound feet of tourque my brothers 1984 Camaro Z28 has. And what some older and newer 350's, 454's and maybe a crate 502.

Thank you all.

If ur brother's z28 has the Lg4 305, chances are that it has 160 horsepower and 235 foot pounds of torque. if u want newer chevrolet engines, order a GM Performance Parts book from any dealer, for about $5, it has all crate motors that chevrolet offers and dyno charts for each.

What was the biggest mass produced V8 every built???

Post-World War II and put into a production light-vehicle, it was the 500cid (8.2L) Cadillac engine. Followed by the current Chevrolet 8.1L V8, if my memory serves me correctly. The upcoming Viper/Ram Pickup V10 engine will be 505cid (8.3L), but you said "V8".

Does it necessarily have to be a gas motor? Detroit diesel and navistar have built some HUGE engines, more than 12 to 20 liters of displacement

I've seen production (road vehicle) engines over 16 litres...but I limited my response to "light-vehicles"...those with GVWR of under 10,000 lbs.

chevrolet (gm really) still makes all of the engines...but none of them are put in cars. if you go to the gm web site you can find that they still have the 454 and 502 in the inventory.

i think gmc may have put an 8.1 liter engine in one of their suburbans in like 1995 or something. 8.1 liter should be the 502 if i am correct.

a 502 isnt 8.1liters its more like 8.2L or 8.3L But Dodges 505ci V10 is 8.3Liters... So im guessing its 8.2Liters... ugh why did they have to go Metric??? i like saying i have a 383... when honda's have like 100 cubes.. its funny to see them realise how small their engines are.

a 496 is 8.1liters < thats whats in the new Trucks and Vans... it's what should be in the New Vettes.

What ever happened to those Big Block Vettes? I mean i know what happened... but why not have them? 8.1Liters would be nice, if the Vette team tuned it up a bit, it would make decently high HP and TQ ratings. Would give Viper something to worry about. Not that the Z06 isnt already, but we could always use more grunt!


383... thats what? 5.9Liters? cause a 400ci is 6.6 (according to my friends old 79 Trans AM) Or is the 383 over the 6Liter mark? Ugh.. once again STUPID METRIC!

Anywho thats my 2 dollars worth

ZOOP! 6.6! Actually the 403 is also 6.6, thats what my T/A had

I can't think of a "mass produced" V8 engine in excess of 500cid (8.2L). The large diesel engines from Navistar, Detroit Diesel, Cummins, Volvo, Mack, et al...are all six-cylinder engines. If there was a truck V8 greater than 500cid, it would have had to have been produced before the 1980s...and probably back into the 1960s or earlier.

If we're limiting this argument to "light-vehicles" as defined earlier (GVWR of under 10,000lbs), I'm going to agree with the 500cid Cadillac engine.

Again, agreeing with what has been said, the Viper engine is 8.0L (488cid) for the first generation and 8.3L (505cid) for the second. GM's big gas engine is 496cid (8.1L) and it's only been offered since 2000; prior to that, the largest V8 in a GM light truck was the 454.

I don't understand how all of these big displacement engines have such low HP. Granted, that is a lot of torque compared to the HP, but my cavalier almost has 160 hp.

What gives???

no offense to the 305 fans, but the 305 isnt the best V8 built. the 305s of the mid 80s sucked balls Smog regulations kept the V8s from making serious power. but with minimal investment a 305 can make good power.

for example the infamous Chevy 350 has made oddball hp throughout the years. In 1970 they generally made 350 hp (sweet!) in 1977 they made 170hp (what the shit?), in 1986 it made 250hp (getting better).. in 1999 it generally made 280-350hp (depending on the Vehicle and its performance options) its the regulations. All you have to is let the motors breath and bam you got yourself a powerhouse.

Hold on a sec. Comparing the numbers on sixties and early seventies motors with their counterparts in the eighties isn't right unless you take into account the fact that it used to be rated in gross hp and now is rated in net. Net doesn't look as good on paper. There is about 61 cubic inches in a liter. And to throw my opinion in, I would have to say that most of the time, peak hp is overated. You have to look at the power curve. If a car has a flat curve that doesn't peak very high but is 20hp less than a curve with a steep peak, that vehicle creates more power throughout the band and will most likely be a higher performance vehicle.

thats very true...

i wish i had friends as smart as you. sometimes we just stand there saying 'power good!... gas price BAD!' thats pretty much the extent of our conversations... yep.
