: I'm itchy I gotta run it!!!!

Well I've managed to make it through most of the summer, doing the cruise/car show thing. I have one more big show to go to (Frankenmuth, Mi sept 9-11) But I'm tired of not having an answer as to "What's it run in the 1/4??" ..So since summer is winding down,and the car isn't "new" anymore, I want to take it to the track. (Then if something does break I have the winter to fix it). I've been down the track a handfull of times. So I got the basics. ...I figure and oil change, check the plugs (replace if needed) check the timing, then go over everything to make sure everything is tight and adjusted. The local track is a IHRA track. My aeroquip (socketless) fuel line is legal. Wil I have any issues with the short sections of rubber lines going to my trans cooler?? I'm sure the car won't run anywhere near the 11.59 number requiring a roll cage . (My 4 point is not welded to the frame in the car) I do have new racing laps belts, NNS, rad catch can, proper battery hold down, metal divider in the trunk, shut off switch, and a vent for the fuel cell. (this does NOT have a check valve) So I guess I'm trying to think of anything that I've overlooked.

My other big hurdle is my tires....I'm running M/T Sportsmans.. 31 x 18.5's I know these are meant for the street and not the strip. Is it a lost cause to even try and run these?? I know on the street they don't hook at all, even rolling along. Now I've never tried to heat them up first either. Will lowering the air pressure a bit even help?? I hate to invest in slicks for a one or two time adventure to the track. But if all I'm going to do is spin, why waste the time?? I guess I can try and buy or borrow some used slicks for the day. I have drive shaft loop I can install (required with slicks)

I'm really curious as to what it will run!! Seat of tha pants feel is pretty good and I would hope to run a high 12 or low 13. If you haven't checked my website...it's a 468 BBC with 063's bigger valves, around 9.7:1 comp, old school 292 hyd cam, RPM intake, 750 vac sec with proform main body, shorty headers, 3" exhaust with ultra flo's, re-worked TH350, Coan 10" 3,000 convertor, 4:10 posi in a narrowed 12 bolt, all steel except hood..I would guess around 3300,3400 lbs.

So other than the questions reguarding tech, should I start looking for some better tires so I can get better results???

My '69 with a .030 over 454 with 241 oval ports , 10:1 comp, 292 hydraulic cam, Weiand Team G intake, 850 double pumper, turbo 400 with TCI 10" and 4.10s ran 12 teens so I don't think you will have any trouble getting in the low 12s

With some launching technique i would think you should easily be in the low 12's, and those tires arent terrible, they are better than street radials!

When are you planning to do it? I'd like to tag along.

31x18.50's are a pretty big tire. i would think at that weight you will be somewhere in the high 11's if you have everything including the chassis tuned in real good.

Lowering the tire pressure will make a big difference. I had the hoosier quick times, which look almost the same as the MT's. With normal pressure around 30 psi, they would spin and clean the street. Dropped the pressure to about 12 psi and I would almost dead hood, it was like night and day.

Thanks for the words of encouragement! I guess I need to brush up on getting it to leave half way decent. I hope it will run the numbers you guys think. Of course the driver has a lot to do with it :clonk: We'll see if he's worth his salt. Like I said, I 'd at least like to know what she's capable. I will post my times, good or bad when the day comes.

T-man...I want to do it right after the Frankenmuth show. So as long as the weather holds it will be soon after. It will be a Friday night T-n-T for sure. I will let you know so you can come out and have a good laugh!!!!

One more thing.....should I bypass the water box????

You mean to Frankenmuth?:D You knew if I saw this I couldn't pass it up without some kind of comment.
