I've crossed the scales at 3350 w/me in the car and a 1/2! tank of gas. . . still had A/C when I left too. . . stock k-member, no carpet or interior to speak of, but with what you've listed, unless you're a fat-***, you should be there.

Constantly looking for things not needed and lighting existing parts. It does'nt hurt that my car is a hard top. Alot of it has been little bits here and there. 40# off the crankshaft, 26 off with my own custom exhuast. near 40# with my 18's ...26# more with my dr and skinnies, 28 out of the k-member I did, 7 out of front bumper, 10 out of rear bumper, jack+spare, air pump, 5# out trans crossmember, alum rear control arms...and allot of lighting holes that I done a very nice job on...on bolt on parts only. Lots of little bits add up. I have taken a little more than 300#'s out total while still having a car that's comfortable to drive anywhere in the country.

I've still got all comforts but weigh 3500 lbs last time I scaled it. Didn't know you could get 40lbs outa the crank. Dang!

not really out of the crank..off of it. My clutck pp and flywheel weigh 17#'s. the underdrive pulley is about 5# less....Rotating weight makes a big difference. This thing rev's faster than I've ever heard a ls rev.

theres the lightweight carpet, and cutting any unnecessary brackets off,big difference with racing steering wheels, rear seats weigh a good bit, all tubular suspension,no front sway bar, airbags, light weight battery?, sound deadening, drag racing seats and rims, if you dont need music radio and speakers, i race my car with my seat and seat belt and carpet no other interior

My formula tipped the scales at 3440 without me.. I have Umi K-member and lower control arms, no rear seat, no powersteering or ac, no windshield washer,
but I do have a LQ block, and a Th350, with a Moser 12, so I guess that is where it is coming from.. Btw this was on my ZR1 wheels, 17x11 rear, 17x10 fronts..
I am looking forward to some race wheels, and maybe taking alittle more out of the car, to save some weight..
I also have no front bumper support.. but its not a DD either..

You guys don't even want to hear that I"m aiming for 2800 with an iron block motor LOL.
I think with a FI setup on it, the car will end up around 2900 to 2950 tops, and that's with most likly a 25.5 cage in it.
All depends what you're willing to live with. I'd never do 2/3 of what I've done for a street car.

It's a tilton racing 5.5 triple disc. I worked on road race cars for 17yrs and that's the clutch we used. I made it fit mine...all bolt on really. I though about putting together a kit but it would be pretty expensive and guys on here are weird...they'll pay $1000 + for a junky replace type clutch but not $2000 for a fully rebuildable race proven one that will actually make your car faster. I probably have the only f-bod in the coutry with this set-up thet's daily driven. There is no such thing as a sticky or non-realiseing clutch any more.

^You should start off by showing a video of the revs because I wanna hear it. Theres 2 things in this world that make me tingle. A super fast revving engine, and a hard hitting cam.
Well, and the guitar solo from Cemetary Gates.
