'00 S10 4.8 Dyno Results Ok here it is: Stock 4.8 w/Sanderson shorties, 2.5" y-pipe to 3" cat and pipe through a Dynamax muffler. Built 4L60E and built rear w/3.42 and eaton posi. 97* out and no humidity. Dynoed on a Dynomax loaded dyno (similar to mustang dyno). Numbers are: http://i264.photobucket.com/albums/i...ynoHPandTQ.jpg Tuned by Ryne at CMS in Lake Elsinore. A/F ratio: http://i264.photobucket.com/albums/i...ynoSheetAF.jpg I personally think it's not that bad for the smallest genIII LS motor and 140*+ IAT's (nothing I can do about the IAT's either). So lets hear what everyone else thinks! |
Not bad at all. What year is the 4.8? |
not bad atoll! :thumb: thats around 315-320bhp mill the heads, thinner gasket, LPE GT11 cam or 02 z06 and will pump out some more hp |
Motor is from a '03 Silverado I will be looking into '03 ZO6/243 heads, cam and springs. Already freakin bored with the power level and it hasn't been a week!! |

The advantage in being bored with these motors you add some boost and the affair continues to grow....MP-70 would put a smile on :cheers: |

I'd go with something a little bigger on the cam. Your best bet would be a nice turbo setup, then maybe I could see the LS6 cam. I know other cams will pass smog also, but you cant beat LS6 cam and springs! |
Nice, did you have a build thread on on of the truck forums? -SS |

243/799 are the same design. same thing as ls2 heads real ls6 heads have the lite sodium filled valves. |
i have low miles set of 799 if your looking:) |
The 243 heads that came off the Vettes had lightweight valves also...but the ones from the GTOs did not.... |

Very nice, like said above it would be cool with milled 799's and a ls6 cam! |
I've always thought about a 4.8 swap in something cause of the rev potential from the short stroke. |
