That run was....
1.35 60'
3.85 330'
5.95 1/8th @ 117.7
7.7 1000'
9.37 1/4 @ 132
Mike's car always seems to run quicker in the second half of the quarter than the calculators say. the calculators estimate the real quarter time at 9.22 with those 1/8th numbers.
The launch on that run was 14.5 lbs when the T-brake was released, and quickly(less than half a second) it reached the 18 lb peak. After that, it varied between 16.5 and 18 lbs. All of this at basically 14 degrees timing,11.0 to 11.5 AFR, and the awesome E85 fuel(that I tested a little higher than 85 percent)
The next run, It broke.
The launch would have been the same, but it would have ramped to alittle higher boost, and then carried that boost better than the 9.37 run. But the little Powerglide, could not take it. And this powerglide, was no weak built unit. The stock 6.0 should have broken first.

Congrats on getting it rolling.

Thanks,
This was a long week. All this, after spining out in the rain and hitting a guard rail near the Milan track. then running 11.50 on 215/75 r15 tires at the Pittsburg track, the first run at hebron was an easy run, Just to get a timeslip for the completion of the 1100+ miles of HotRod DragWeek. Then we did some 1/8th mile runs to make sure all was good with the track and car.
BTW, the car weighs 3300 before we put the dash and console back in, and then weighs a little less after we hit the guardrail.
Our 14.5 lbs is on a stock head, and tiny stock 01 z06 cam, so if we weigh the same,and sixty the same, then we are probably leaving at the same "power" level regardless of the boost numbers. Mikes car has 325 DragRadials and I think we can hit it even harder. If we had the power, and obviously the transmission.

drove 3 hours to the closest 1/4 mile track yesterday. had a great day racing.
mikes car was not hooking well at first but between tire pressure changes, rear shock settings and more burn out it came around. might have been the track that came around but most others didn't seem to be having any problems so i think it was us. ended up running a new best everything. i think the numbers were 1.34 60', 5.91@117, 9.27@144. numbers are off a little up top. it has been pushing water when turned up for months and i think on that last run it finialy pushed the head gasket out for good. i think he was leaving at 10-11psi and running close to 20psi up top.
mike is trying to decide what to do next. we have an aluminum block 5.3 sitting here. might just toss that in to see what the change in cubes does and the loss of 80lbs off the front of the car does. it would be a neat experiment. might just put some fresh head gaskets in there and try it again. might put is some head studs or might not. it would be sweet to knock out a 8sec pass with a stock longblock but at this weight that might be asking too much.

changed cam, changed valve springs + pushrods. Untouched rod bolts, untouched head gaskets, UNTOUCHED ---torque to yield---factory GM head bolts.
9.27 @144 on an engine you can buy from your local junkyard.
Not surprising we have lifted the heads, REALLY???
And now we hurt the gasket, on the fifth low nine second run, in a car that weighs 3450 lbs with driver
We can swap in another 6.0, or the 5.3 I have and try some more.
For persective, If this had been in our old Fairmont, that weighed 3150, this would have been an 8.99
This is a nice start to our season. I think.

Just put some arps and new gaskets in it, that is the only difference on mine and no coolant pushed. I'm just on junkyard sh*t in both my cars too, smaller motor though here only a 5.3 in each, no 6.0 and I run a smaller turbo. I figured you would have arps/new gaskets in it, that is why I said I was surprised you pushed coolant.
To be honest it sounds like you have a nice setup, I fully expected when I saw this build that you will take the stock shortblock record from me. I figured you would mph more though, my ltd only went 2mph less with a 76mm, jy 5.3, less boost, way heavier, and definitely not setup for optimal drag racing as its the DD. You should be able to get it up in the 150's I'd think with it being a 6.0/88mm.

My junkyard 5.3 with single 76 went 147 mph with no water moved at all and it was stock gaskets/bolts etc.This was in my mustang @3250lbs

That was with the old converter and trans, and we had to bump the limiter at 6800.
The same converter restalled, was 6700 the next time out when we ran the 9.27@144, and now with a little Hy-guard in the mix, we have been 144 @ a little over 6000.

Jim(Parish), Mike,and I all went up to ThunderValley in South Dakota Sat.
And we have a new best,
1.272 sixty foot
5.705@121.36 1/8 mile
8.982@147.16 1/4 mile
Fox body@3400 lbs, 6.0 truck motor, powerglide, pt88, Megasquirt II, MSD 6010 Non-intercooled, e85.
http://neufamily.org/images/mikessta...arion%20sd.wmv
Still stock short block(90k mile 2 years ago) rod bolts,rods,block,crank,pistons,and the ring gaps are untouched. Everyone seems to be talking about these needing to be opened up since that HotRod artice, and it may be a good idea, but we haven't done it and this still lives.
I think, we are pushing a stock short block harder than anyone, ever has!!
This engine has held up to alot, same one form DragWeek last year, same one from the 9.27 earlier this year at the SouthDakota Track, and this 8 sec run is after 4 other attempts, at 9.106, 9.125, 9.124. and a 9.08.
The eighth mile runs are crazy numbers, also. 5.70, 5.80, 5.81, 5.78, not in any order. With a high of 122.xx mph in the 1/8 th.
The old style 88 seems to be falling off at the top, I think if we had a 4.8 or a 5.3 we could push to a part of the compressor map that would gain a bit. But maybe it is time for a 50 shot in front of this 88

you guys should think about getting a youtube account. the vids would load a lot faster.
ok, its official . the ls6 cam is proven. for sure that is what i will go with on the next build.looks like changing rod bolts is now officially a thing of the PAST.
