Suppose you wanted to install the basic LS engine and manage to get by with its plain Jane horsepower, simplicity and reliability being the priority.
Further suppose you just keep the basically stock suspension and car, i.e., wanted only plug and play LS engine.
Ballpark, what would that weigh and cost, for the LS engine and conversion kit?

Here are my weights for comparison. LS1, full interior minus rear seat, roughly half tank of gas.
Total: 2950
LF - 780 lbs
RF - 741 lbs
LR - 690 lbs
RR - 748 lbs
How does that compare to a stock turbo?

How much power and torque does your LS1 make?
Ballpark cost?
Fuel efficiency vs. turbo?
Noise?

Since you're in Washington, why don't you go drive Squire's car. He'll let you take it for a spin and answer all of your questions.

I got a LS1 out of a 2004 GTO it is rated 350 crank HP/350lbFt IIRC. The LS1 in a corvette was slightly more and the one out of a TA was less. It depends on the car it came from. They have slight differences with intakes, some LS1's run LS6 intakes, or have a true dual exhaust making that car make more HP. It is easy to get some HP with intake, exhaust and tune just like anything else.
Fuel efficiency should be about the same as the car it came out of. The last V8 motor I had got better mileage than the V6twin turbo car that replaced it.
Cost is relative. The actual bare bones replacement DIY isn't that bad. It's all the little while you are in there stuff that kill the budget. My budget has been thrown out. What started as just replace the motor has turned into a new interior and suspension rebuild. The motor still isn't in there, but that is another story.

Rated at 405Hp in a Corvette will make about 410RWHP and about 380RWTQ with my cam/headers/exhaust/tune that I'm using on my current LS1.

Car and driver need to go on a diet
Maybe it's time to get rid of the boat anchor of an engine and go for an LS.

Well, had a little set back last Wednesday. The U joint on the steering shaft broke. So that got replaced and the steering shaft repaired. Unfortunately that meant that the car wouldn't be ready for the track weekend.
So they slowed down a little, mounted the catch can, got the AC lines done and the AC charged. The car should've hit the dyno today for final tuning.
I haven't heard from the shop yet, when I do I'll post up the results. Barring any other weird failures I should have the car this weekend...

Doc- how much does this project run from the shop? I know how much it would cost me to do it, roughly anyway but I know I want this in the future so checking out the options.
