I would probably do the 6.0 route and do all the supporting mods correctly, like new built trans and a good converter to match.

As for a good combo, look at peoples vehicles and see what they run or look in the dyno sections on LS sites and if you see a combo that works well try to attempt and copy the setup.. A lot of guys do that.

 

Wish I could find a 6l for $100!!!
like mentioned its plug and play, slide a cam in while the motor is out, long tubes, converter and custom tune

 

we have what we call Street Nite every friday or saturday(i'm sure yall have something similar) and once i get everything built right i plan on being there if not every weekend every other weekend...i was thinking 6.0 with the tr224, the edelbrock pro flo intake with a built 80e, still not sure on heads though

 

And thats at the drag strip by the way...whoops also 3000 stall

 

The proflow is an awesome intake. Other options are the NNBS intake, and the LSXrt 102mm intake is a proven performer. Although Fast has had some fitmit issues lately. The Built 80e is a great route. For the heads it depend on if you want to go FI or not. Want to keep the compression around 9.5:1. If not look for a set of 243 heads and have them milled down a bit.

Also, Different types of FI like different types of converters

 

I was just looking around and maybe 317 p&p patriot gold valve springs and valve job?

 

The 317s are a great head for FI. If your set on the 3000RPM converter would work well with the Procharger. Maybe the radix. But you would be better off with a 2600-2800 converter.

 

So with the 6.0 i could build it 317 heads and the edelbrock intake and throttle body ****** my 5.3 out and put the 6.0 in and send the computer to blackbear get it back put it in and i would be driving? Correct?

 

Yes, But Blackbear can send you the flashed PCM. Just gotta send your old one back to him. So there is no down time.
The stock tb is a 78mm 3 bolt and the Pro Flow uses a 90mm 4 bolt TB I believe.
Edit: Looks like the Pro Flow has mounting holes for both types of TB.

 

Ok good deal going to pick up the 6.0 tomorrow thanks for all the help guys!
