I'd love to, but 10K for a shortblock! OUCH!!!! Add the heads and everything else.....................Might as well do the 408 and the blower and call it a day.....

It would be cool to do something a little bit different then the status quo...

Any idea what a 408/TVS 2300 would run in a Silverado SS (AWD)? It seems like everyone that has a similar setup is either much lighter or heavier or running 44" tires like yourself! On paper, it seems that a combo like this should run 10's at 5500lbs (My SS race weight), but I haven't seen anyone do it yet..........

I think I could budget build my 6.0 with some forged pistons and put a TVS 1900 and go mid to high 11's now. Unless the 408/TVS 2300 is worth some decent gain, it's not worth the expense/aggravation to me.......Or maybe it is, but it would be nice to know someone has already blazed that territory

a 2300 tvs with any cube in motor will be lucky to run 10's in an ex cab ss on blower only . just not enough blower .

someone prove me wrong but i dont see any 2300 making more than 10-12 psi on 4xx cube lsx's which isnt enough to propel a 5k + lb truck to 10's . you need around 850-900 whp to run 10.9's in an ss.

in my case i ran a bit quicker with more power and some downfalls. it will not be cheap no matter what , everything needs to be addressed. fuel,trans,motor,forced induction, suspension/traction.

i have done alot more than what is minimum needed to run these times but i wanted a show stopper as well.

and btw i had a 427 not a 454 , i didnt want the 4.100 stroke associated with pistons coming down and causing oiling problems . with a longer cy;linder sleeved block it would be better but the lsx block has things the other stock sleeved blocks dont , now a sleeved lsx may be an option . ill have a 436-438 soon with the dragonslayer 4.00 crank and a 4.130 bore . going for 9's with a few more upgrades though, 4 link and a cell and remaining awd like common sense told me i cant do.

Trevor ran 11.3x in an ext cab with TVS 1900, just a 5.3 tho.

Chase isn't Joe@leftcoast running 2x lbs on a 4xx in motor with a 2300?

Good feedback thus far.

I think Trevor went 11.60 or 11.70ish on blower, but his truck also weighs less plus "I believe" he removed a seat, spare, etc. Not positive on that though. I know the Silverado SS's weigh more and I don't remove anything (sub box, etc) on my truck. Add to that my 280lbs and still running stock 20's and I'm not expecting the same results. Of course on the flip side, Krambo went what 11.70's IIRC with a radix on a Silverado SS. Not sure if he was full weight, drag wheels, etc???? I guess the 6.0 is actually helping more then I thought. I would be curious what his truck would have done with the TVS 1900, maybe overspun a little too if a radix ran that good.

Here is where I get a little confused. If I built a mustang (something I'm more familar with) with a Vortech centrifugal blower with a 302 based motor and say I was running mid 12's on motor. Bolted the blower on and dropped well into the 11's with say 10 psi of boost. Now I build a 408 and throw it in there and run mid 11's on motor. I put the same blower on same pulleys and make less boost, but also run deep into the 10's. In essence, I've made a more powerful engine and the blower has just enhanced it considerably.

That theory doesn't seem to apply consistently to positive displacement blowers. In other words, if I get my truck to run 11.80's - 11.90's with this radix, I'm not expecting it will run much better with a 408 with the same blower. This is probably because the blower moves xxxx amount of air and when trying to feed the larger engine, it basically creates a bottleneck. I can buy that, but you would think a bigger blower like the TVS2300 would have a little more leg to it.

IMO, the positive displacement type blowers really are the **** with these heavy trucks if you can get them to breath a little up top and you have AWD. Being able to use the tighter converter (and not sacrifice too much or any performance) is awesome when you daily drive something. The TVS line of blowers really seems to shine here (torque but breath decent upstairs) but they also seem limited in size from what you guys are saying here......

Turbo is looking better and better.......

Here was where I was going with the large cubic inch idea. Obviously expensive, but I think a large engine like a 482 or 500 motor while very expensive would easily put one of these trucks into the 11's. Add a TVS2300 blower on top of it and it should "in theory" push the truck into the 10's.

But based off the feedback above, it appears the blower isn't large enough to support the cubes so it would be just like me putting my radix on a 408.......

The flip side is the cubes aren't going to help with gas mileage and that does matter a little since I drive my truck daily......

I'm thinking the 370" motor with a nice turbo is looking better and better every day........

Thoughts?

I had a 1900 on my camd 5.3, then put it on a high compression 408. Same exact blower. Going from the 5.3 to the 408 added about 200hp. With the same pulley the 5.3 was at 11lbs and the 408 was at 5lbs. The blower only moves a set volume, but as boost increase it becomes less efficient, ie takes more power to drive.
