Somewhere between 300 to 310 rwhp. About 300 rwtq.

300 rwhp is right on for a dynojet 243 with corrected D/A. 280rwhp on a mustang dyno.. A dyno is just a baseline for stock motors all the way through different stages of modifications... If you do a search on this forum you will find bone stock Ls-1 corvettes vary from 275rwhp to 350rwhp.. Its nuts. There are just way to many variables to compare from one to another.. Most forum members believe a dyno number is a dyno number is a dyno number.. Kind of like getting on a scale and weighing yourself and then comparing it to someone elses weight... Wrong Wrong Wrong... But members continue to post and compare numbers,, Its really pretty damn silly.. Take it out to the track.. Get some good practice and launch education from Rangers posts and give us your times.. Your trap speed will be a much more accurate indicator for rwhp

I put mine on the dyno last week (321/338). Mods include Magnaflow w/x-pipe & Honker intake (~20 hp) so 300 sounds about right:
