Ok. I just bought desktop dyno 2000. I also scrapped the idea of buying a ramjet. Too much $$$ not enough power. Does anybody know how accurate Desktop is. Heres what Im building. 350 with a lt4 hot cam, etec 200 heads with 1.6/1.5 rollers, flat top pistons and sd tpi intake with slp runners/ 1 5/8 headers and loudmouth exhaust. So the dyno says 504 hp at like 6500 or something and torque never drops below 400 after 2000 rpm. I just dont like how it has too many generic values in it, like headers with mufflers and so on. Oh and thats with the cam retarded 6 degrees.

 

About as accurate as G-Tech numbers are in my opinion. Do you belive your numbers for Dyno 2000???

 

it was pretty accurate for our engines. The valve sizes were wrong in the files I got and hp droped to around 400s
