Silvermodo's iron 347 pulls like crazy on 8psi..

Stock48 is running 10.3s in his Regular cab Z71 with a 370.

 

I will make decision. PRobably do ls1. Im going get some more info myself. I will update with yall asap.

Im curious why two different with alum and iron block? If I go LS1 should have alum block? I know it is lighter than IRON. But dont know why two different. Do you know what I mean?

 

just do a TVS1900 and be done with it

 

:stfu:

 

I dont want have supercharged. I had one long time ago with different vechile. I like turbo much better

 

WHAAAAAAAAAAT???? You can not not be impressed with a certain someone's truck dyno and track #'s

 

I find turbo's more impressive. And cooler. Several on here have gone 10s all boost with simple turbo setups.

 

I will go 10's next with all boost.. Ohh but I have a blower

 

Make sure you're at 4950 lbs race weight. Dont forget the 80e swap either for added parasitic loss

 

4400, through a 60e



Seriously though, leave that 5.3 in there till it pops. Put a decent turbo cam or ls6 cam in it, boost it to the moon, with a good tune..
