I know a little someting about ls1's so shout me a PM if you need some info, and who to talk to.
As Far as 600 Hp, 20mpg, and normal sounding. GOOD LUCK

Not to be an ass, but if your doing natural asperation, your going to have to go with an insane heads/cam setup, with which is going to have a huge lope and sound like a fucking race car.

Also, depending on what you want to do with the car, look into getting a formula and not a TA, that way you can get a hard top, and race it on the track, have it a little stiffer than a t-tops car, unless you are just doing quarter mile passes and street racing.

Not taking you to be an ass, but again, there are probably some things you do not know about regarding modern racing technology. Some of my mods will greatly inprove horsepower while actually improving gas mileage slightly.

Camwise I was thinking of something along the lines of 228 duration at .050 lift (single pattern cam), with a .588 lift and a 114 lca, I will probably run it 2 degrees retarded. Don't run the numbers on it through your calculations, you will come up 90-100 hp and 80-90 ft/lbs of torque short of what my combo will actually make.

I like the TA's, it will be stiff, even with the t-tops after I finish with it.

It would be tough in any automatic, but with a 6 speed, and on the highway, it's doable.

Explain why a 6 speed would yield better gas mileage than a 4 speed auto with a lockup converter on the highway.
