Is there anyone on here that actually knows what they are talking about?

    290ft-lbs @ 2,000-2,300 rpm and a new shot at more in the spring with unported but NMRA F/S prepped GT40P heads.

    Not bad what was your torque peak and have you ever posted your latest dyno graph? Would love to see it.

    Tom you're running shorty headers and stock pistons?

    No i haven't scanned it yet because my scanner gave up the ghost. I will scan it and the new dyno when it is done and post them on the link below my avatar. Edit: you can find my first untuned dyno (39# fuel and 13* timing - vs 42# and 18* now) by clicking on the "my garage" link below my avatar. I carried 275ft-lbs on it in the same rpm range and averaged 285 ft-lbs over the entire 2,000-5,600 rpm dyno band.

    You can't view them because they do not have a file extension or formatting that windows recognizes - such as jpg, gif, tif, etc. If these files are at the dyno shop, ask them to save them in a format that windows can open.

    Yeah I figured it out, I was able to view them, but was wondering how I can save them to the computer and put them online for those non believers.

    Also my car is at 260 rwtq at those RPMs, so im nowhere near that low end torque!

    260rwtq is very believable! Try hitting ctrl print screen when you are viewing it then paste it into anything you can...i.e. Photo Editor, word, etc.

    VERY nice "stock" head torque curve.

    Thanks, and as well all know, its all about the area under the curve that matters, not necessarily peak numbers, yet most focus on the peaks!

    Its funny, I compare my dads GT-40P car to mine, and mine makes more torque until about 4000 RPM where his catches and passes mine, and makes peak torque a little higher up and then drops off. His power does the same and passes mine at about 4200 RPM and then peaks very slightly higher than mine!

    Its funny, goes to show what the right suspension and such will do, his car makes a few more hp and a few more tq, and I have gone 12.11 in it at 110 mph, weighing about the same!

    "Ok here it is..."

    Huh, everything you have listed in your sig is stock untouched (other than maybe a valve job)? Where is the cam installed, I ask because every dyno I've seen of stock stuff dies out around 4700 rpm but yours is pulling up until 5500rpm.

    Look at my first dyno in "My Garage". Stock 88 SD cam that peaked at 4,700 rpm but lost very little through 5,400 rpm. His heads are working well with the combo like my GT40P heads.

    "His heads are working well with the combo like my GT40P heads."

    I can see the 145cc runners of the GT40Ps pulling that high but I've yet see the 124cc E7TE runners pull that high. Most ported E7TE's I've seen struggle to pull past 5200rpm.

    Stock bottem end in the car, the heads have valves in them, but are not ported (I had pics of them before they were installed but havent been able to find them, I might get some new ones when I take the head off to do the freeze plug). The intake is an unported Cobra, 65mm TB off a 93 Cobra, 75mm MAF, rockers, full exhaust etc...

    My car starts to fall off just over 5000 and stays steady till around 5500, hence the reason I shifti it at about 5600! MY dads GT-40P combo is shifted at 5800!

    5,000-5,200 is about where the Thumper/tmoss lower combos peak out HP with a moderate cam from the dynos I have.
