    the little 4.8 that could (on the Dyno)

    Well I strapped the hooptie to the rollers today. I was pretty happy. The dyno was a dynojet at PSI performance here in San Antonio. I will load the copy in a couple days (printer is down.) It laid down 445hp and 441tq. On one run it laid down 449 tq. I am really happy. It's a 4.8 with small cam, Front mount 70mm turbo with Intercooler putting out 10psi. Built trans and small converter with 3.23 gears. Let me know what you think. dang scanner wont get the whole page. I will rescan once at work

    Very nice for the 4.8 in a driveable combo. Get the boost creep figured out or is that in a topic I have not seen yet?

    Cam is a 212 216 .524 115 lsa, Its a KB racing kit, little modified. Turbo is MP70mm Trans is 4l65e built locally here in San Antonio. Converter is a Circle D restalled Trail Blazer stall around 2600-2800ish. The Rest of the facts are in My garage link in my sig.
