I've been searching and trying to find anyone who's built one. Has anyone heard of an LS383 that's been blown or turboed? My 5.3 iron block is in the machine shop and I should be installing it this spring, can't wait! I'm hoping it will outpull the N/A 408's and still get some decent mileage.

They claim 30hp and 17ft/lbs with the LSXRT on a baby cam 383...
