My junk runs 10.0s and sometimes dips into the 9.70 range with great air. It's a rather lightweight(2770 lbs w/me in the seat) '70 Duster.
I will start at the upper front and work down ans back. The motor is an R1 345" W2 solid roller motor. The heads are really heavily worked w/ 2.08" intakes and have been through the hands of three head porters. They flow(on a real bench) 324 - 326 CFM at 0.675" lift. The flow numbers are from worst port to best. The car has a ported Holley Pro Dominator with 660 ctr. squirters. Compression ratio is 13.8:1 w/ Diamond pistons with an ancient 5/64 ring pack; and it is equipped with a 0.695" lift custom Comp roller cam. I just added new Comp Pro 1.65 roller rockers that I bought from a guy on Craigslist. The cam specs are 276° @ 0.050" Int. 283° Exh. LSA 106° ICL 106°. Comp solid roller lifters.
The bottom of the motor is very 1990s, with the old Diamond slugs, a really heavy 4340 crank, Mellings HV oil pump and a home brewed extended pan, pickup and windage baffling and some other oil mods to keep oil it the pan during wheels up launches.
Ignition is also old school with a Mopar electronic disty that I reworked, a chrome box, an old Accel coil, 9mm wires and some other junk that I have done as I am an EE by training.
Backing the motor is a slick-shifted(yes, the build is that old) A-833, narrowed Dana with 5.38s(a real Mopar Perf. Narrowed unit) and a partridge in a pear tree.
Suspension is really simple with ladder bars and 14 x 32s at the rear, and 90/10 shocks at the front. The front shocks are old Gabriel units.
Car is pretty light with fiberglass doors, hood bumpers, deck lid, and lexan glass save for the back light(rear glass).
It is also green. If I was a better driver the car would be in the nines with regularity; but I'm not that great a driver. However, I am honest about my lack of driving prowess :)
