1972 Datsun 240z

Small cam
TH400
3.54 with 25" ET Street tires

Last month I took out the car for the first time and ran a best of 12.02@113mph. I kept surging through my brakes at the staging lights and couldnt launch the car over 2000rpms. I installed larger front brakes along with a fiberglass hood and some rear end parts. You know, shot gun method.

Today I still pushed the front end over 2000rpm, but I was informed that the wheels where not moving. So, I dont know, I guess its a convertor issue. So instead of trying to launch at a higher rpm I just stabbed it off idle at the tree. Seemed to work out and get me my 11's before the season was over.

My big project over winter is to pull out the th400 and go to an overdrive transmission and then finish the suspension so I can get a taller tire under the car.

Good ol' Sac Raceway. Congrats on the pass, car looks pretty consistent. What's the raceweight? And what's Foster's car running nowadays?

congrats Jared. You def built a quick car.

Thanks man, but Fosta had a big hand in it. I'd still be rocking a SBC if it wasnt for him.

Hahaha.

I am just assuming but I think my car is sub 2600 with out me in it, there wasn't much weight gain from going to the LS pattern iron block and the aluminum blocks are fairly close in weight to the original inline six Datsun motor. Where I did pick up alot of weight was the Infiniti rear end conversion and the th400.

Nice runs! I miss my sbc powered 70 240. Plan to get another someday. Sac is my home track too so look forward to checking your z out.

s30

Thanks! I used to have a sbc in my 240z few years go, it was fun but it was a huge gas guzzler.

Just a quick update, new best is 11.77@117 with the same set up. I didnt do anything over winter . The next time I take the car out I should have the nitrous installed.
