2000 silverado rclb to rcsb drag truck low budget conversion

I read through a good chunk of the thread. Like others said, it 'd never pass tech. But even if it did, it'd be in a class of vehicles that it can't compete with. Being back halved doesn't let you run in anything close to a stock class. And the reason the truck won't stop spinning is the majority of weight was removed from the back. Trucks already suck in this department. My bolt on TBI 4.3L spins street tires on pavement. In the beginning of the thread when the op removed the tailgate and the back bumper I was thinking its going to be a mess. Then I skipped ahead a few more pages...

Didn't say it smokes the tires or anything, but its a truck. From a stop it spins. All I'm saying is a gutted, severely gutted, truck will never hook up on the street. The front to rear ratio must be horrible on that truck.

Alright, we gotta put this into perspective here and go ahead and disprove the whole "a truck is light in the rear so it can't hook" bullshit. This is typical talk of car show guys and those that don't really do anything surprising when the tree drops.
Here is the perspective. Lets look at a "gutted" mid-2000's full size rcsb truck. Most are gonna be over 4000 lbs, but I'll even make it more unfair and say the truck is 3850 with a 60/40 weight split. Thats 60% of the weight on the front and 40% of the weight on the rear tires.
3850 with a 60/40 split puts 1540 lbs on the rear tires.
Now lets look at your friends fairly gutted fox body that comes in at a fair 3000 lbs ready to race and give it a 50/50 weight split.
3000 with a 50/50 split puts 1500 lbs on the rear tires.
NOW TELL ME AGAIN HOW YOUR TRUCK IS TOO LIGHT IN THE BACK TOO HOOK UP!!!???

I can see where it would be the first thing one's mind might run too when it see's a truck because it IS nose heavy. But the fact is, the whole truck is heavy. So, the fact is that probably all streetable trucks and most race trucks (one like mine for example) still have more weight on the rear tires than the average f-body guy for example.

If you want to get into really extreme examples, the outlaw drag radial guys are actually adding significant weight back to the front of their cars (and have been for some time now) to help keep the front down. A really good 3300 ODR car that runs deep in the 4's in the 1/8 mile can have as much as 56-57% of weight on the front end. So that car would be something like 1419 lbs to 1452 lbs on the rear tires. A far cry from my nose heavy gutted truck the last time it was scaled. My truck the last time it was scaled was 4110 lbs with me in it with a 58/42 split. That's 1726 lbs. on the rear tires.
The ODR car I mentioned above at 3300 lbs probably 60 foots somewhere in the high 1.0's to the low 1.teens. That's with around 275 lbs of weight less on the rear tires than my truck.

3.42 gears and 28s helps it out, but it could use more gear honestly. Steep hills around here make it drop speed easier. Not sure why its such a big deal I posted even my truck can spin the tires on the street. Just about any vehicle out there can. It's not like I said my truck with slicks smokes the tires down a prepped track. It's just a 4.3L but it does make its power down low, when I dynoed it the starting speed was the max torque of the run. It was only 200 foot pounds but it was more than I expected. Too be fair I don't have performance street tires, I have General AT2 tires. When I had BFG ATs it spun easier, those tires aren't as good as the Generals in any way. The first year or so it had Wild Cat ATs and with those cheap tires it'd spin way too easy. To the point I couldn't even give it half throttle from a stop. But with good tires its gotta be to the floor. If I had some of the tires you guys run it probably wouldn't spin at all on the street. But it's not a race truck, so I keep AT tires on it. It get stuck pretty easy with anything else. I'd almost run mud tires on the back but then it'd suck on ice so I figure these are a happy medium. I'm not gonna fill this thread with stuff about my truck so if you want to see the stock 4.3L truck and what little that's been done go to my intro thread.
