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

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

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

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..
