So you have 4 bottles in your car? How much you use every time you go out?

It's a race motor, no street at all...2500lb Camaro has ran 9.60 index on 10.5 turns of the throttle stop. Next weekend taking the stop off and seeing what she'll do all out.....This is what 10.5 turns looks like.....an asthma attack to say the least.

Another vote for some heads from Chris Frank. Seen some of his heads in person at the LS fest. They really are an amazing piece to see.

Just got off the dyno this past Tuesday, made 740HP @ 7000, 598 ft/lb at 6000. Going to make a few minor changes/fixes and dyno again in a couple weeks. Has another 30-35HP in it easily.

That's awesome. Was that on a engine dyno, and was the vacuum pump running?

JS01

Yes SF902 engine dyno, and yes vac pump was running but not at full efficiency only 8-9" instead of 14-16" like I wanted.

Hard to imagine a LS motor leaking what with all the o-ringed cover gaskets it uses- front, rear, valley, oil pan, and even the valve covers. Guess all that's left is to pulley down the vacuum pump?

It wasn't leaking we pressure tested the crankcase, it was pulling alot of oil into the pump after about 6000rpm. Going to make some changes there.

Update: The car is now up and running. Once the break-in period is done I will have it dyno tuned and see what she puts down.
