I am pretty sure i can get the hp up more but the tq has me concerned???? Don't know what to do to get it up higher. I would say it's the c/r. But not sure. Maybe advancing the cam??? Any suggestions??

process of elimination...
start with the easy stuff first.
Get a cutout and re dyno to see what you gain,
and if your still not happy with it...
spray it!
your numbers are not bad at all considering the rear end ya got.

haha definately call bs on that one...all the higher dyno cars never want to post graphs, i have out of the box 205's and a very mild cam, a lot smaller than this one, and make almost 50 ftlbs more, reguardless, every TSP cammed car i have seen is weak esp with the torque numbers and dont even get me started on their heads, first hand experience tells a totally different story then people posting high numbers and not backing it up with info. i live in the REAL world, along with everyone else

My old tsp 231/237 cam made 396 on the tq side. But it was a totally diferent setup. I never was crazy about the 113 icl on this cam. I have always had a 112+4 icl. I would assume that would effect the tq on the ms3. I will say my old f14 cam with stock heads pulled alot harder than this setup. But thats just sotp.

I think I am going with the FAST 90/90 before I do heads, and see what kind of numbers I can get out of my TRak. 43x/40x isn't out of the picture. With heads, who knows!

unless u throw crazy compresson and a good head on the car with a TSP cam it wont make squat for torque. (in reality we arent here to rip you just to give you and others real reasons for the low numbers as they are not unusual with your head/cam setup)
what is the compression at BTW?
