I have a 2002 Cadillac Escalade engine H.O. High compression 10:1 motor.. I'm planning on swapping it into my '99 A4 Z28 this summer. The 2002 stock Escalade numbers are 345 HP and 380 Torque. I'm just wanting your inputs on this engine and which cam to go with. I want to make big power and crazy torque and still drive it around town all on a budget.. HAHA.. I'm not palnning on having it bored, and I plan to use the stock flat-top pistons.. I got a good deal on the engine and I'll probably have some minor porting done on the D-port heads. Essentially it's going to have all the bolt ons, cam, headers, stall.. What kind of power and torque could I potentially make given the Escalade is dyned with a restrictive exhaust, 3.73s and Huge *** rims and tires.. I would think 450+ HP and Tq are possible.. Cam suggestions are welcomed... I will be driving this car on the street and occasionally on the track. I've been dreaming about this for a while and I finally rounded up the engine.

Thanks

is this a joke
i hope so

Please tell us why this would be a joke? I'm interested..

Why,heads/cam headers would get you to 425-440hp without the extra weight.Sounds goofy too me.

well there are plenty of people putting the low hp low compression 6.0 in their car. I haven't heard of many putting the H.O. Escalade motor into their car. I want a high Hp and Tq motor that I can run 100 shot on all day. I wouldn't mind hearing from the big dogs on this topic. You can laugh at me later when the car is done. Then I'll know if it's a joke or mistake. I just like to be different. I fell off the bandwagon a long time ago. If I can have low buck motor stay together I can figure out a way to compensate the extra 75 pounds or so. Move the battey, get rid of the air pump, egr etc.. I love how people are so quick to judge. That's cool though since it comes with the territory.

I have 6.0 block in my car ,dont know if I am a big dog or not(see sig).Anyone doing low compression 6.0 is strapping a blower or turbo to it.Not quick to judge here just offering advice.If you got great deal on 6.0 I would sell it to someone with a pickup apply profits to h/c headers tuning.No matter what you do for weight loss you still have 75lbs more than if you did same stuff with alum block.A simple cam swap would give you more hp than escalade engine,I guess to each his own.

you should see what the base cam specs are like, then get a custom cam ground to make more of an emphasis on those specs...but all in all, it sounds like somethin to try out with these cars. someones gotta do it

Good Lord, can we stick to the topic? I'm well aware of what LS1s can do. I've had my car for three years, and have had heads, cam headers.. blah blah blah.. I appears that this motor is a joke to some because no one is running one and appears to be little info on it for our application. Hell over on Ls1.com they think the escalade motor is the same as the regular vortec.. No offense to you with the big dog statement. I know of countless problems with aluminum blocks and NOS. My thinking is the higher compression would give me the power I want for a NA setup as well as take more of a beating with the juice????
I still love how the ignorant wicketmike chimes in.."Is this a Joke" hahahahah That's cool.. What cam do you like for this 10:1 6.0 motor?

Thank God for a positive person.. I'm starting to believe that people aren't wanting to try something unless it's proven.. Thanks man..

Well, first of all, the 345HP figure has nothing to do with gears, rims, tires, etc. It is a motor HP figure, not RWHP. Pick up a brochure for any new car, and they give you engine HP, not RWHP. New cars are not dynoed. So, that "345 HP" H.O. Escalade motor probably only produces about 15-25 more HP then a run of the mill LS1. Also remember that the truck engines come with an improved intake manifold that will not fit under a Camaro/Firebird cowl, so sweapping to a LS1 or LS6 intake will cost you another 10 or so HP, bringing the gain down to only ~5-15 more HP than the LS1. So, you wouldn't gain that much. Yeah, you might get 450 HP WITH a cam and some heads, but you could do that or more with a LS1. With that motor and only a cam, you would probably get to about 380-400RWHP (Thats on the generous side, considering you're an A4), or about 437-460 engine HP. Not saying its a bad idea, you're just setting your goals too high, IMO. Not to mention the weight gain that would probably cost you a tenth and would need 15-20HP extra to gain it back. All of this is my own opinion, and you can take it or not, but don't be disappointed to find that you invested all of this money in a engine that offers you little to no gain versus what you had. Then again, what do I know, I'm no big dog.

Good luck, though, I guess you'll have to try it and prove everyone wrong. Just be sure to post the results either way , fair?

By the way the HP and Tq number are kind of up in the air.. I know of someone that took a stock low compression 6.0 rated 325/360 in a truck, swapped it directly into a F-body. It was a stock motor minus swapped stock ls1 parts. He dynoed 340/340 hp and tq to the rear wheels.. That given if the H.O motor makes 20 more hp and tq than the regular vortec, It might be a 360/360 engine in an F-body.. So the HO might not be as shitty as everyone is thinking. BTW I have very little money in this motor.. I can sell me 1999 LS1 and almost make my money back.. I love this.. Opinions please...

Kind of like a stock Camaro LS1 dynoing 290-310RWHP bone stock with an engine rated at 305HP? If you're expecting 360 RWHP out of a stock 6.0 "H.O." engine, well, I think you'll be .

So you're telling me the H.O. won't make anymore power or torque than the regular vortec 6.0 that made 340/340 in a camaro? Whatever.

I like 6.0 heads, i like 4.00" bore, iron block will retain more heat(hp) thru thermal efficiency,if you can shave the weight difference i think this is a great idea. Aluminum 6.0 blocks are on the way, GM is still the best!

No, the H.O. WILL make more power and torque than the regular Vortec.

Well, without calling , I doubt that "I know of someone that took a stock low compression 6.0 rated 325/360 in a truck, swapped it directly into a F-body. It was a stock motor minus swapped stock ls1 parts. He dynoed 340/340 hp and tq to the rear wheels." I doubt this because the manifolds, intake, exhaust, etc would not allow this motor to dyno 340RWHP in a Camaro. Those 6.0L engines both have better manifolds, intakes, exhaust, etc than an Fbody does. I also know that 6.0L truck manifolds nor intakes will fit in an Fbody. So, I find it extremely hard to believe that anyone with a motor that was rated at 320HP put a more restrictive intake and exhaust on it, and gained ~85 RWHP?

Simple math makes this impossible:

320 HP (flywheel, you're quoting from the owners manual, I presume) rated 6.0, minus 20% drivetrain loss (probably more in a truck, but we'll call it 20%), equals 256 RWHP in a truck with better intake and exhaust. Then, install 256RWHP engine into a Camaro, put more restrictive intake and exhaust manifolds on it, and dyno 340RWHP. A gain of 84RWHP? Sorry, that doesn't happen.

So, back to the question of "I know of someone that took a stock low compression 6.0 rated 325/360 in a truck, swapped it directly into a F-body. It was a stock motor minus swapped stock ls1 parts. He dynoed 340/340 hp and tq to the rear wheels." Assuming it really made ~265RWHP, instead of the 340/340 that you/he claimed, your "H.O" 6.0L probably will produce 20 more RWHP than his. About 285-290RWHP.

Not to mention the car now handles like A$$ because its nose heavy, and you are slower at the track due to the added weight. Also have to remember that you are going to lose more power exponentially from the intake and exhaust defiencies exponentially as the motor production grows from the regular 6.0 to the H.O. 6.0.

Again, I hope you get what you are looking for, but I think you'll be disappointed tremendously. Like I said, let us know, prove us wrong. Or not.

Remember that these are "quoted" numbers, not RWHP numbers. A LS1 is rated at 305 or 315 HP. The "mack daddy" 6.0 is only rated 30-40HP more than the LS1, with a better intake and exhaust. Put LS1 intake and exhaust, and I'd bet you'd be lucky to get back to 305-315HP.

i think you guys are on the wrong track, take a stock 6.o, put on some 5.7 heads, hell even millem a little, nice cam and headers, everything you would normally do to a 5.7 block and i think you will be suprised, now if you leave the low comp. heads on then ya it wont be impressive...there was a threrad on here of someone doing that...sux2bu was his name but i cant find the post...

You've got to be kidding me.. My LS1 with a K&N filter did 308 RWHP Is that not close to 305 ratings? RWHP figures seen pretty accurate with the GM ratings to me.. Do you really think the 6.0 would be in the 200s hp wise if dropped into an F-body. I don't know where you're from but there are several cars down south here in Texas that are making serious power with low compression 6.0s.. Anyone else care to chime in. I don't think the spank man has a clue.. I'm gonna put down some power..
