well, as a few of u know, i have an iron ls1 shortblock i bought. along with it came a comp xr281hr cam. specs are 228/230 571/573 112. Im dropping in the ls1 in about 6-8 weeks. So this friday, im gonna put that cam in my 4.8, and have Charlie retune it. I know I know, ppl are give me **** b/c they say its too big, but i wanna see how well it will run. I have a circle-d 3k stall, 4.10s, lts and an awsome tuner, so we will see how she does!! i will put up a vid as soon as i do it.

 

<---- interested!

 

I firmly believe that there is no replacement for displacement, and more cubes is always better. However, I think that the 4.8/5.3 engines have alot more potential than everybody wants to give them. It's nice to see people starting to get a little bit more 'radical' with the smaller cubes, to see what can be done. Up here, 6.0 blocks go for a premium because of the mentality that the smaller engines are no good. Some of us know better.

 

exactly what i set out to do! people still thought i was crazy or throwing my money away. I'm excited to see what track times/dyno numbers you come up with.

I am in the middle of an experiment myself. I am trying a different intake than most are willing to try and got the heads done up. Hoping to hit mid to low 12s on an n/a 4.8l in a truck body

 

im only doing this because i am doing an ls1 swap soon, and i already have this cam that came with my shortblock i bought, so...why not!!

 

got bigger injectors ?

 

i have 8.1s

 

Subscribing

 

More cubes is on the way,but why not play with the 4.8 for the last 6 weeks it has left in the truck
Can't wait to rev it to the moon LOL
Hell we ought to go strap it down on the dyno this weekend.

 

cool, good luck with it. how about trying the edelbrock tunnel ram intake?
