I dont judge much by mph seeing its a high stalled drag car and it was a windy day yesterday but the car is running stronger in the upper rpm range and its safe to say the heads helped up there.

all the info there, be nice if a lot of guys from LS1tech showed up. I'm surprised they havent made the 300 cars but being Easter weekend in the south that probably has something to do with it.

Hmmmmm 291 miles.....
Really id only need to be there Sat morning and could be home around 2-3am on sunday.....
I agree with ya about the whole to close to Easter thing....
Tech looks like it will be real loose too....
Now i just need to ask the wife LOL
What day you heading that way Kev?? Friday for test and tune and staying the night???
Doesnt even look like you have to pay to race..... they pay you if they choose you.....
Just show up huh?? or sign up???

Only thing is if you do get 'picked' to be one of the final 16 expect to be there until 2am or so.
Its a 1/300 chance of winning 10K, thats not really bad..

Congrats on the times !!
But aside from the heads, have you done anything different in the head gasket area ?
New studs, different torque spec ? different gaskets ? Or just re-using the ARP and GM MLS..??
I think I spoke too soon in the last thread. Mine temp guage has started going up and down on the way home from Scotland, but mostly running cool. Seems to be getting air locks in it.....possible sign of leaking HG's
Although I did first run this engine last May, and I havent had to touch it sicne then. So cant complain I guess.

I could look between the block and heads and you could some black between the head and deck under where the plugs are. If you dont see anything there you are probbaly OK.
Same studs, little less torque (75 instead of 80), 5.7 instead of 6.0 GM MLS gaskets and of course the new heads.
Jerry I would have liked to go to SDR yesterday, heck I'd like to go to evey track every weekend but diesel fuel prices are getting out of hand along with everything else. Its costing 200-300.00 just to go make a couple passes these days so i'm trying to limit myself to once a month instead of twice like I usually do - car should last twice as long anyhow
ty_ty13, it may help some, just doing it for the weight mostly. Plus the 1-2 shift is right at the 60' mark and lots of times the front wheels arent on the ground yet. I could do an a sloenoid shifter I guess but the glide will be easier to hook up at marginal tracks.
NA$TY-TA, thats sucks - thats the way stuff usually works for me lol.
Tnaks Kurt, still going strong - so far the short block and the rear end are the only things that I havent had out of the car in over a year to get redone. To me running low 9s with a small cubic inch engine with the amount of passes I put on and its running FASTER after a year is pretty amazing - must be seating the rings in finally

I did a coolant system test just now ( for combustion gases ), and at idle, small rev etc as per instructions, it doesnt really show anything. Fluid colour doesnt change at all.
Ive a few other issues to sort out with the car, then I think I'll pull the engine and stick new gaskets on it anyway

Plus now I'm pulling 1.5 degrees of timing at 7 seconds into a pass and 3 degrees at 8.5 seconds in so that should be easier on things also. We'll see as the passes add up though.

Good news is four passes and didnt push a drop of water.
Bad news (sorta) is the car picked up a sold tenth in the 1/8 with the way it was with the Dart heads. I use a TAG to predict my ETs depending on the DA and its been within a hundreth or so all last year with the D1/3.7 pulley. It said the car would run a 5.93 in the 1/8 (+300' DA), right off the trailer it ran a 5.90 but let off at 1000' or so since the track was a little rough last time I was there. Still ran a 9.30 @ 137 with a 1.27 60 foot.
So checked the water, pulled it around and stayed in it the full 1/4 - ran a 5.84 and 9.186 @ 147 in the 1/4 (1.270 60').
Checked the water, pulled it around again, spun pretty bad and aborted it and drove right back around and ran a 5.82 1/8 and 9.182 @ 144 (let off a little early and it was pretty hot) with a 1.254 60'. That is an amazing 60' on that little boost.
The car has run faster with the F1A and with the D1SC with the 3.4 but I didnt expect it to run what it did with only 15psi and the 3.7 pulley. Never pushed a drop of water either so I'll just leave it for a while. One of the few times I tried to slow the car down and it went faster lol.
No vids this time

But i have pulled a lot more timing out and ran it richer in the past and it has slowed down quite a bit. Hard to tell when you change something major like a set of heads, these AFRs have a completely different chamber design then the Darts and most likely are better cylinder to cylinder being CNC'd as opposed to as-cast. I am running it in closed loop right now and its using less injector duty cycle then it usually does to keep the a/f so thats a good thing I suppose.I'm trying my best to not be too optimistic about the head swap but if they dont push any water like this after 50 passes or so any added performance is just icing on the cake. I really didnt expect much of a change but it appears to have picked the car up some.

Man you sound like a smart guy, and I love what you had to say about having a fast/safe race car and not worrying about the extra .1 or .2 at the track. You need to start making your own Bio-Deisel it's not that hard and usually can be made for around $1 a gallon. Will make those long drives to the track ALOT cheaper. Good luck on Pinks, the show is kinda gay, Rich C. needs a kick in the *****, why they don't race from a Tree is still beyond me. Win one for the LS-x guys
