SO you think a LS1 has weight??
Motor doesn't have fluid in it or the water pump....
But looks like I need to cut my front springs.
few other shots.

That is for weight transfer at the track. 
I really like these conversions. Thanks for keeping us updated.

I switched to the QA1 Semi-coilovers after cutting and cutting of the springs. Once you cut 1 or 2 coils off, bump steer starts kicking in. A simple solution would be to add a bump steer kit. Happy cutting.

Ahh, my car does that, mostly at low speeds when braking, such as in the dips usually found at traffic lights. Not the brakes, I dont think, as they seem fine on a nice even surface. Same thing?

Also cutting the springs will make them stiffer, Less suspension travel, less bump steer.
For the performance suspension (F41, Gymkhana) Chevy put heavier springs (550lb) in to reduce bump steer (amongst other benefits).
If you can remove bump steer then you can go with the softer springs and control them with good shocks for better ride and handling. Norval used 260lb springs at one point.That's with a big block with steel heads and supercharger.
BTW, to remove bump steer you need to redesign the steering set up. I used an End Take Off rack and I have 0 bump steer throughout the suspension travel, except for the last 25mm of droop. The wheels would have to be off the ground without shocks to see this area of travel.
If you didn't know, springs are rated on what force creates a certain travel. Therefore 550lb springs require 550lbs to compress them 1 inch. that's why they are shorter than softer springs. A softer spring needs to be taller to support the same amount of weight at the same height.

Although it effectively changes the "toe" setting it is not related to the static toe setting done during an alignment.
Basically, what I am trying to say is when you hit a bump or drop into a pothole the car steers to the left or right.
If the car searches at high speed on a smooth road then the alignment needs to be redone as the suspension is basically static and no bump steer can come into play.

Don't worry about the steal... I don't care...if anything this brings up a very good point that we all deal with...
And looks like something I will need to correct also...
I guess more reason to save for a C4 frame over the next 5 years.
All these C3 handling and steering issues try to get our cars to move and handle like the BIG BOYS.

This bump steer is what I feel pulling me left under acceleration? My car is sitting too high front and rear but I wont lower until I am finsished working on it which will include some lighter parts. Will lowering solve some of my problem?

i don't think that is bump steer you have going on ....i think that is worn components/alignment issues
