My truck has great throttle response compared to the hemi that I drove. The reason hemi truck are like it is because of the drive by wire system system. From the start the computer must pull major timing or something becasue everything doesnt catch up and feel good to around 3000 rpm. Since I installed the longtube headers on my truck I cant go 50% throttle or my tires start to spin bad. We can run up to .600 lift in our trucks and .551 with no problem. I also had to order Comp Cams 918 springs (rated at .600 lift) and hardened Thunder Racing pushrods.

Onequik5.3, I'm not going to try and make excuses for the Hemi but, like you say, add an intake, exhaust, and pulley the blower for 13-14lbs. of boost and I believe a couple Lightnings will be carrying ass whoopins.
Also, do you have that cam installed already?

I looked on some websites for cam specs. Comp was too hard to search, but looked at some on others like Crane and their big ones were around .530 lift and required a set of springs and other goodies to run.
Still, better than I thought you could throw on an otherwise stock engine.
I am kind of surprised Chevy didn't go "modular" like Ford and Dodge with the OHC design.
I can still change my two cams in less time, so I'm happy with that.
Today I was at a light and some older man had a new Chevy which was assumed to probably be a 5.3. I was in the right lane and he was in the middle. I knew by the way he was looking and staging the light that he also was going for the shopping center on the other side of the light and when the light turned he punched that sucker and I did too. I spun more than I wanted to. I also assumed I'd catch right up easily but didn't. He stayed almost a truck in front of me until 60 where I then turned right into the shopping center and that sucker had to take the next entrance down the road LOL!
But anyway. He had a RC 2WD Chevy and I had my QC 4X4 Dak and I wasn't able to take him like I wanted to. Time for more mods I guess. If i just had the 4.10 gears it would have been no problem.
The bad thing is for each little mod i do, i keep adding weight to my truck rather than remove weight.
I've got my truck box with misc tools, tire chains, gear for riding quads, along with a subwoofer box and two amps. It probably all adds up to a few hundred pounds. And I want to add a push bar.
I'll have to do some major motor work some day or just wait for a good S/C to make up for some of it. my truck still puts down a good a$$whoopin every now and then, heavy 4X4 or not!
And it is more fun to whoop on a fart can Ricer than another American truck.

GraphiteDak, look at www.thunderracing.com and you will see the cam, go to GM fullsize, valvetrain, and click on the TR220 112 and the graph is posted on a RCSB 5.3. No I havent got it installed and probley wont. The reason I just got another job (THAT MAKES 2) and I decided to sell the cam only and save for a ATI Procharger D1SC, with the 3 core intercooler and 8 rib pulley system and a 4 inch pulley for around 11psi. I can get the whole thing for around 4K so I should have it my June. I will also have to buy new injectors and a Walbo pump. I am also am going to do the cam but instead of the TR220 (Which isnt a supercharger cam at all) with the VHP Vinchi High Performance 045 cam made by Crane thats suppose to by dynamite for supercharger applications. I will keep the guys that are intersted in my rig posted hopefully Procharger and several other said I can hit over 500 rwhp. The trans aint gonna last at all.

The Procharger sounds like a good investment. Hope everything works out well with it.
A 4l80E with a shift kit and an upgraded valvebody should do the trick for tranny needs.

I am surprised at the valve height available with ONLY spring mods.
many OLDER small black heads could NOT support that valve height. had to get the heads modded or go aftermarket.
I have no clue what the limits are for a stock 4.7 engine. KRC sells cams up to .502 lift. You only need special springs as well. I wonder what kind of power you would get with the Ross 11:1 pistons and the really hot cam? It says peak power is at 6800 RPM's.
And again. You could change both cams in a 4.7 well before you could on a 318/360 or any small block Chevy.
I think the 4.7 is quite a bit more advanced. Too bad they don't make a larger engine in the same design. There is NO Bullsh*t bolted onto these engines. It's a very easy engine to work on.
It would always be easy to make a setup like Duner's. He's running a home made turbo pulling good mid 12's on a STOCK 4.7 RC Dakota. I've watched him race personally. He said he had like only $2000 in his turbo setup.

Onequick5.3 I have no clue what happened to the Hemi you drove, but I have a 2005 Hemi with an anti-slip differential, positive traction in a way, and I can tell you, the throttle response is great, both tires start spinning and the truck goes sideways instantlly. Thats as good as throttle response as i need. My buddy owns a 2002 silverado with a 5.3 and i smoke him big time, my throttle response is much better than his, and when he raced me in his Tahoe with a 5.3, i smoked him even worse. He nailed it off the line and couldn't even get the tires to chirp.

Here's what's funny. Those Tahoes must be heavier than we realize or just be underpowered where Torque is concerned.
Because I've messed with other guys when we tow our Quads and my little 4.7 4X4 QC Dakota will WALK away from them Tahoes when we're both pulling ATV's! I once (crsazy as he11) messed with one so bad that we were kind of racing on the way back from the dunes (I8 from Yuma to Phx).
He wouldn't quit trying to keep up going faster and faster so I got back on mine and he obviously hit his ~105MPH limiter and I let OFF at 115~120MPH while towing my trailer. It was very breif and I know it's dangerous. But it was funny. He couldn't keep up on the hills OR on the flat for top speed. Sucker! I don't really care about needing to go that fast on interstates anyway. But having the power that little engine makes on them hills is great. I wonder how much better going to the 4.10 gears will be.

Dingleberry, what kind of Silverado does your friend own 2wd or 4wd ex cab? What kind of ram do you own quad cab, rcsb,?And I agree that a vechile such as a Tahoe doesnt accelerate worth a crap becasue they weigh so much and the power is made in the upper rpms. When I bought my truck it had a Magnaflow exhaust on it. It would run 0-60 in 7.0 flat all day. Since a new exhasut Borla, KN FPIK, ASP pullies, and the Longtubes and tune it runs 0-60 in 6 flat!! And I can do it pretty regular. And watch out for some Tahoe's I think theres 3 on LS1tech that runs mid 13's without nitrous.

onequick5.3 My friend owns a single cab 2wd. I own the single cab 2wd with the sport package. Don't get me wrong his silverado is quick, just not as quick as my hemi. Especially going about 60 then racing...my top end is much better than his...his truck does 0 to 6 in about 7 seconds as well...Don't get me wrong about those Tahoes either, racing one from 25 mph will give you a run for your money...They have a little kick to them.

Scott, can you please clean up your sentance a little I cant understand what you are trying to say?
BTW, the some of the fastest trucks in the world are 4x4. Launching in 4 hi is pulling some impressive time expecially when you have 700rwhp.

I've heard "stories" of people running in 4HI on the street. also hear when the transfer case DOES go, it's bad :-(
I usually only flip mine into 4HI when it's been raining out in which I'll admit I do that stunt quite a bit when it DOES rain here anyway.
the truck sticks so good in 4HI that you leave your stomache back at the stoplight!
It's funny getting lined up with someone you KNOW wants to get the same lane you do to go to a shopping center, etc on the other side of the light! they never have a chance when you hook up better in the rain in 4HI than you can on the dry in 2HI

My near stock 4X4 will snap you back into the seat as it is! I wonder what that would be like with an additional 100ft Lb engine?

onequick5.3:What do you mean clean up my sentences? I guess if you need a 4x4 to get 700 hp to hook thats your problem, most people use slicks. In my opinion 7oohp isnt hard to put to the ground in a 2wd truck. The 2wd truck will be lighter (easier to get out of the hole) and faster with less power! I dont know if anyones ever told you about a little thing called power to weight ratio??

What I think is impressive about his truck is the motor. For a stock 6.0 (and a large turbo cam) that handeled I think it was 16psi and a 75 shot in the same run!!! He finally blew the motor up becasue a nitrous silinoid (spelling) got stuck open and it literally blew the top of the piston out. Then he threw in a 4.8 and had it up to 20 psi and according to the G Tech was running mid 11's with the little 4.8. His new motor is a 408 cubic in monster and with his G Tech is running 10.6 on 13psi!!! The motor is built to handle over 20 psi of boost. He dynoed the new motor and it was only mid 450 rwhp but they think it was having traction problem on the dyno. Within the next coming year I look at it to be the first LS silverado in the 9's.

What does that mean???
Power to weight ratio is fine expecially with 700rwhp. But even with slicks you would still smoke em with that amount of power. 700 hp would be very hard to hook in a truck, first theres literally no weight over the rear tires except for the bed. Did you know one of the most common problems in trans going bad in trucks is wheel hop from spinning the tires? I have been in a 600hp procharged 2wd truck and there was no traction at all. We literally caught traction with the speedo pegged over 100mph. And that trucks got over 17,000 in the motor and blower. The trans has a 3500 stall and he got a Eaton posi and 3.90 gears.
