For conversations sake and out of curiosity...

6500LB 2015 2500HD. L96 6.0L vvt

Cam longtubes and exhaust.

Prices are similar for an lsx 454 shortblock and a whipple kit.

I have a feeling a whip or a procharger would make more power slapped on the 6.0L.

But wouldnt it be cool to have a 7.6L 454LSx ?

All things equal. Motor to motor. VVT1 Cammed 6.0L vs VVT1 cammed 454LSX. What power increase etc?

What kind of gains would be expected and is it even worth doing?

Again this is for conversation sake. By no means am i gonna go out next week and buy any of this stuff lol. Wish I could afford that!

 

The 454LSX is awesome, How ever I don't think you will see the longevity out of a stroker that you would a 6.0L.

 

This.

I wouldnt put a stroker in something you want a lot of miles out of.

 

The LSX block has longer cylinder sleeves to address the issue a lot of people have with the bigger strokes in the truck blocks.

I would do the blower if it were me.

 

what heads? you compare cost of a short block to a blower so are you planning to run stock 6.0 heads on a 454?
sounds like a typical dreamer post.

 

Total dreamer post. I cant afford either right now. Just wanted to hear some opinions on the 454LSX and if all things equal how much more power would it make. What would ir be like. Stuff like that.

I have stock heads. Theyre 823's. L92 heads.

 

Youll need heads to match the 454 your current heads would choke **** out of that motor

 

Badass NA engine would feel alot like a procharged smaller engine. I wouldnt bring any less than 10k with me to build a 454LSX.

 

Yeah it all gets up there in price.

Im browsing ERL performance website. You can send them a 5.3L block and apparently they can re sleeve it with their stronger sleeves which stick out further down in the block to help with piston rocking on stroker cranks at bdc. And they can bore it out to 4.185.

5.3L to 7.0L is possible it seems. Sounds like a neat idea.

Imagine $2500 for their sleeve job and $2500 for a 427 rotating assembly and $1000 for odds and ends and shipping. 5 grand for a 427 doesn't seem too ridiculous.

 

Then another $2000-$3000 for heads, and $1500 on intake and TB and you are about right.
