Guest 73TPIZ Posted January 18, 2004 Share Posted January 18, 2004 Mine's a 305TPI w/ 700r4. Crane 2-5k cam, L98 heads, block huggers, cut-outs. Runs in the 12.80's @ ~104 w/ 3.73 R200 rear. 8.20's in the 1/8th, 1.8's 60ft. these are when she's hooking. 13.20's, 8.50's, 2.1's when she ain't. Just upgraded to 8.8 solid rear. i drove it up and down my street 1 time but haven't made a run at the track yet. Runnin' 3.27 gear now. i liked the squat and leave of the IRS, but the 8.8 should allow me to wail on it with slicks without crossing my fingers every time. But this means i'll prolly bust the tranny soon Quote Link to comment Share on other sites More sharing options...

Guest stpdfst_in_TN Posted January 19, 2004 Share Posted January 19, 2004 zfan, Do you know how much your car weights and your approx HP? What rear gear are you running? I'm currently building my '78 280 with a 383. Your times look awesome and you still have the independant rear suspension. Congrats! Quote Link to comment Share on other sites More sharing options...
Phantom Posted January 19, 2004 Share Posted January 19, 2004 So does an LS1 count as an SBC? LS1/T56; 3.70:1 R200 LSD in '77 280Z. 225/50-16 street radials, car weighed 3,085 with me in it. 12.95@110mph; 2.05 60' & 8.86 1/8th. CAr chassis dyno'd at 311 RWHP & 326 RWTQ. At least it's a comparison with a manual vs. automatic and heavier 280Z vs. 240Z. Quote Link to comment Share on other sites More sharing options...

Guest zfan Posted January 20, 2004 Share Posted January 20, 2004 My car weighs 2760 with me in it. The rear gears are 3.70's out of a 1987 300zxt. I have no idea what horsepower it makes as I had just dropped the motor in the car with less than 100 miles when I ran it at the track. With some tuning it is noticably faster I think now, maybe low 11's, who knows? I guess it is probably 350 to 375 to the rear wheels.

Pyro Posted January 27, 2004 Share Posted January 27, 2004 1971 240Z lowered 1 inch 15" centerlines (8's in back and 6's up front) Heavy springs in the rear with raised spring perches No sway bar honda crx seats no roll bar white auto meter gauges 2600 lbs empty 362 sbc (3.550" stroke and 4.030" bore) 11.3:1 cr (flat tops, zero deck block) iron eagle heads (64cc combustion chambers, 200 cc intake runners) cast crank with 4 bolt mains 292H comp cam performer rpm intake holley 750 3310 carb 150 shot N20 (I use a 1 gallon fuel cell in front of car with racing fuel for N20 fuel enrichment) GM T5 trans 3.90 r200 diff brake linelock MT slicks (26x8.5x15) sintered iron clutch full lenght headers with 1 5/8 tube, 2.5 inch exhaust, two 2.5 hooker areochambers. 10 gallon fuel cell and mallory 140 pump 10.7 sec at 134 mph, 1.5 sec 60 footers, 6.9 at 110 in the 1/8 mile. I finish the 1/4 mile at the very top of 4th gear. The car drives well on the street and doesn't over heat. (Black magic fan with GM radiator) My times are slow compared to the mph because I shift slow to save the trans. I plan to go automatic, turbo, and a straight axle because I'm sick of breaking parts. I can't race the car anymore until I install a roll cage! Quote Link to comment Share on other sites More sharing options...
Guest Fastest240z Posted January 30, 2004 Share Posted January 30, 2004 Mine run's 10.3 @ 131 on the motor with 1.48 60' times. On the nitrous the car has gone as quick as 9.10 @ 149 with 1.23 60' time. When I use the nitrous I leave on the button right out of the hole with my foot to the floor. I don't have any traction problems, but I have had to deal with heart stopping wheelies. After restricting the front end travel to zero, I don't have as much of a problem anymore.

You were the fastest street car there and successfully completed a 30 mile drive prior to the drag race. That wheelstand was awesome when you launched. Is your front suspension beefed up to handle the impact after you come down from the wheelstand? You must have a 4 link rear suspension that is heavily modified to handle those launches.
