I was going to say DA effect's possibly.. It's amazing how much of an effect it can have..

[joeys66pickup]

wasent it like 90* that day? were you at Woodburn or PIR?

[68 C-10 KID]

I don't have any thing to test air levels to see if they are high or low.
I have only went 12.0's @ Woodburn and 12.1's at PIR.
I'm not on board w/ the abbreviation Of DA.
I did put a new ss blaster coil on last night. I need to OHM my old one. I'm borrowing my machinist spring tester this weekend so I can check springs on the heads in truck. I need to invest in log book real bad.

LOL I'm a big dummy. Yes I have noticed that DA can strip tenths away in seconds. I'm putting a new built spec converter in Friday night. They say 5-7% slip only. We will see.

That's haulin there buddy.. Glad to see the changes worked for you..

[69trk]

good numbers!!! I see a cage coming up next

[68 C-10 KID]

Thanks guys. I'm glad its coming around. Now I have a good base. I can start power tuning on timing and jets now. Maybe I can get a tenth or so more out of it. Sure would be nice to get a 11.49 out of it before the tracks close.

It would give me some thing to do over winter. Body work and a Roll bar set up. Maybe a bar set up that's legal to get my license W/ help from a Speed tech N20 system.

[paul1969]

finally made it to the track it was cold as all get out though. think there may still be some left in it. guess i'll have to wait till next year to find out.

[Super73]

Right on.. Nice times..

[AKoldstyle]

how quick do you think a 1972 blazer with a 598 around 800hp with 3.90 gears,29.5 mt et drag radials,a th400 w/o footbrake and a tight 3200 ati converter. rear suspension is ladder bar coil over and vehicle should way about 3000lbs. Im thinking it should run in the low tens. its all metal except for the hood and top. Thanks for any opinions given.

[djracer]

I would be surprised if you got it that light but I would say 9's if you get it to 3000lbs.

[69trk]

I agree with dj, i would think 3000lbs in a blazer would be very hard to accomplish, it's hard enough to get a truck that light.... i would say in the 9's at 3000 also..
