thanks guys for answers. I have some questions more for you.
As I am going to make tubular chassie except front subframes there are many sides how to get best weight transfer, instant centre etc. This is all new stuff for me and I hope here is somebody who can lead me into right path. (I still going to use Caltracs in this project) I mean-explain how and why should I do this and this. Is there some good calculators what can help me?
As Iam going to make new firewall and floor also then Iam able to move motor quite a lot behind and so on...but how much is enough, what should be motor height? Is better to lower or raise motor with tranny etc. As you see, lot of questions (hopefully not too dumb ones)where I need help and hope to get answers. As this is not easy project then I want to make it work first time
I also trie to lower whole car as much as possible

you are allowed 10% of wheel base, try not to go all the way,
also , make youre tunnel bigg enough so you dont have to get long ext and ratchets to get trans bolts out,
also dont want to go back to far on the motor might have to get into the windshield ?
as for how high./low the motor get , depends on where the rear sits, and angle of trans, never want the trans to go uphill, 0 or 2% down (really dont like 0), this is dictated by what ride height or stance you want to achieve?
my motor is moved back 7" less than 10%, but my motor is as low as i can go without the trans up hill, and my oil pan,
i cut up my k memeber is all i use is the bars i have an open area except for the rack/pinion,
good luck

As far as moving the engine back... try to get it at
least 50/50 on the weight(up to 48/52) as for the
height of it.. it will still be 50/50(or what ever
you build it at) BUT if the engine is higher in the
chassis it is closer to the CG height and is easier
to transfer the weight to the rear... what makes the
difference on the height is the amount of torque
the engine will make... higher amounts keep it low

thanks guys.
I start with front K-frame and keep you posted.
What about front stabilizer bar? How unstable car is going to be without it?
One plan is to leave original control arms (maybe modify them and make them lighter), remove torosion bars and use 2-way adjustible front shocks

If this is a drag car you dont want the front sway bar
it tends to slow movement in the frontend
