Thanks for the input so far guys. Good stuff.
Replies to some of the suggestions,
I will prob go with the gun drilled axles and star flanges. Don't know if I can swing the 300m axles or lightened ring gear, but I may try.
I will run 16" wheels, but not the monster size slicks. The 16" wheels will be there for a future upgrade if needed.
I already run the ECAE ultra mini alt. weighs less than 6 lbs including bracket.
For a shifter I will use a Biondo Outlaw. Very small and light.
The gauges will all be lightweight and I will use a K&R wiring kit. The K&R is a really slick deal that uses a single computer type cable from the switch panel to a circuit board that controls everything. Saves alot of wiring and the hassles that go with it.
I have my choice of a fabbed steel (Moser M9) rear end housing or a Strange aluminum rear end. The diff on the rears is a wash. The Strange housing is lighter, but the suspension brackets are heavier. I talked to both Moser and Strange yesterday. Both bare housings with brackets are right around 48 lbs.
I basing the weight of the new car vs old car on one I looked at last week. The car is an American.
I spent most of a day last week at one of their dealers in N Ga. They had a 514 BBF dragster stocl block, out of the box a heads, new style intake w a carb. It was a 235" swing arm. Fabricated rear housing. Nicely equipped, but not alot of extras. Std axles, 16" rears, etc. With a 235 lb driver it weighed 1910 lbs. So, the car weighed 1675 empty. My 225" Undercover slipjoint/hardtail weighed 1600 empty. All of the 4 link cars I have looked at weighed 1680-1700 w/o driver.
Keep the comments coming.
