Thanks Steve,  I will check all that stuff next week and let you know what I find.

Hope your water hasn't given you any troubles!!

So potentially that's caused by a compression issue with mine? So that's why I need the leakdown test and valve train check to find or eliminate that variable?

Trying to learn how to read these, looks like he puts it to the floor, when it hits 3000 rpm he let's it go, spins a bit then hooks and pulls down rpm a bit. Looks like it drops 1400 rpm on first shift that over reved to 6000 and 1000 on second shift.

Was this a trans break car?

would that be because I cant leave as hard on the street as at the track?

Is it giving us any info about converter? at least how its performing at the shifts?

28 inch tire, test pull on the street to 100 mph, not a full 1/4 mile run, all parts are in my signature.

I will try to do the boost test this week.

Got the gauges before I knew better, story of this car, hahaha

I read Steve's post several times. My boost gauge doesn't show vacume, just boost. I can do the test and see when the gauge starts to move.

That log was not a full 1/4 mile pull. When I test on the street I only run it up to 100 mph.

From everything guys have posted, if I understand, it's not terrible in the 1/8 but falls apart in the second half of the track. With the slip am I blowing thru the converter in the second half?


The file said saved in 2018 so that a run with 28 inch tires, and pretty much as it sits now, didn't run much last summer so that's a current situation log

On the log how does the rpm look at the shifts?

Sorry if I'm not following you here, trying to understand it

I will get a dial indicator also....really dont want to pull intake....goin g to be pissed if cam has a bad lobe, was very careful with breakin and always used good oil and zinc additive

The tv cable is set correctly..

I dont know how you do the math but what is acceptable converter slip.....and can you mathematically determine what it would be running with an acceptable slippage number?

I can get a leakdown tester on amazon for $35. I could roll her into the heated shop and check on the items mentioned. No way to run a log for quite a while but I will

Dont i have to pull the intake to check lifters and lobes?

The last run numbers I gave you were with 28 inch tire and it did cross the line between 5400 and 5450. When I had the 26 inch tires it ran the same mph but I can't find any post where I gave the rpm.

Its a lock up and I dont have any logs saved to post, dont think I posted any before either.

Your right it is a lot of money. I have read over and over how these cars need a good combination to work well. Thru my own ignorance I didnt research enough as i worked on this one and kind of added parts as I went and didnt have a good plan for what I wanted. I think as a result I find myself tuning and tuning a shitty combo and just getting frustrated cause it just isnt working

I tried to step back and think, ok, if I just bought this car and ran and tuned it as is for the first year with current results , what would I do. I'm sure I would descide to build what I thought would get me into the 11's. I would check all the basic "engine health" stuff, and mine seems all good, good compression, good fuel system, no exhaust troubles, all good numbers on the scanmaster. So what parts would I buy to get it to where I want. The combo I posted to me seems like a good group of parts that I have read about alot that worked really well for others. But obviously I dont know what to put together or i wouldnt be in this situation :)

Also, I have a buddy with a 700 HP Mustang that can only run mid 11's and i would love to beat him :)

Maybe I'm just talking myself into it??

Thinking about this last night. I have been working on this combo for several years and just can't seem to reach my 11's goal. I'm consider starting over, getting a 6262, a slic , new valve springs and a Art Carr converter and having Eric redo the chip Seems to be a proven combination that should easily reach my goal. I figure the parts to be about $3000. Just sold the wifes snowmobile cause she can't ride anymore so got the fun money to spend. What do you guys think of the idea, and the combination?
