I'm in the process of building a 6.0 for my 99 T/A auto. The car will be some what of a DD and a weekend warrior. So drive ability is important.. of course a nasty idle and huge HP is always desirable, but power under the curve is preferred.

the 6.0 is going to be N/A with 3.900 crank, dss racing 1880-4030 pistons and hand ported 799 heads ls6 intake. I think compression is around 11:1. I have a summit #8707 cam at the moment but wonder if their is better choice. Since their is a lot more experienced people on this site I was hoping to get advice!
Thanks! Eric

Power under the curve usually means you won't have a huge hp number especially with a 3.900 crankshaft. There is a trade off most of the time.

I'd probably drop the exh duration 10 degrees to chill out the idle and guarantee smooth cruising but I'd say if you already got it, run it. With a good tuner it will be fine

98Zeric

I figured I couldn't have both..Unfortunately. But a smooth power band throughout the rpm is what I'm wanting the most.
Thanks for the advice!

Stay under 232 intake duration and you'll have what you want.

98Zeric

very good! Seems like I read somewhere that also helps with driveability. Is that correct?
Thanks tuskyz28

What are the specs for TSP B.F.D 6.0 ?

Bspeck82

no, too big. Stay with what you got or get something in the low 22x/22x range

Tuskyz28

Yes sir

98Zeric

ok, thanks for the advice!

Bspeck82

No problem. Good rule of thumb is find what cam you think you need, then go a little bit smaller. Going too big will hurt a lot more then going to small will.

98Zeric

well, guess I lucked out there. I was thinking about going with a 232*/xxx but decided to go lower haha

I have the 8707 cam in my 6.0 with 799 heads and stock truck intake. Drives awesome great power everywhere and has great drivability. I also run terminator x so I can tune everything myself

98Zeric

thanks for reaching out! Great to hear! I've been kicking around the idea of adapting the terminator X or HP to replace the factory ecu.. for ease of tuning.. with those two systems are you able to tune on the fly? Also can you control electrical shift trans?

Bspeck82

stock computer is way to go. Its very easy to tune and will drive well. Not to mention youd have to piggy back for emmisions, doesn't always drive well, cost more money etc.

98Zeric

oh really, I didn't know it would have to be piggybacked .. maybe I'll just stick with the dyno tune plan... the extra money I'd save could go to something else. Thanks Bspeck

What injector and fuel pump are you running?

[QUOTE=JF74chevelle;20266639]What's the lbs/hr of the injector and Gph of the pump?

[QUOTE=98Zeric;20266689]i have no idea off hand. It’s the fuel pump that came in a Holley sniper master kit that I re-used for my LS swap

thats the pump
